Delegates to an implementation of ISessionFactory that can select among multiple instances based on thread local storage. An IFactoryObject that creates a local Hibernate SessionFactory instance. Behaves like a SessionFactory instance when used as bean reference, e.g. for HibernateTemplate's "SessionFactory" property. The typical usage will be to register this as singleton factory in an application context and give objects references to application services that need it. Hibernate configuration settings can be set using the IDictionary property 'HibernateProperties'. This class implements the interface, as autodetected by Spring's for AOP-based translation of PersistenceExceptionTranslationPostProcessor. Hence, the presence of e.g. LocalSessionFactoryBean automatically enables a PersistenceExceptionTranslationPostProcessor to translate Hibernate exceptions. Mark Pollack (.NET) The shared instance for this class (and derived classes). Initializes a new instance of the class. Return the singleon session factory. The singleon session factory. Initialize the SessionFactory for the given or the default location. Close the SessionFactory on application context shutdown. Subclasses can override this method to perform custom initialization of the Configuration instance used for ISessionFactory creation. The properties of this LocalSessionFactoryObject will be applied to the Configuration object that gets returned here.

The default implementation creates a new Configuration instance. A custom implementation could prepare the instance in a specific way, or use a custom Configuration subclass.

The configuration instance. To be implemented by subclasses that want to to register further mappings on the Configuration object after this FactoryObject registered its specified mappings. Invoked before the BuildMappings call, so that it can still extend and modify the mapping information. the current Configuration object To be implemented by subclasses that want to to perform custom post-processing of the Configuration object after this FactoryObject performed its default initialization. The current configuration object. Executes schema update if requested. Execute schema drop script, determined by the Configuration object used for creating the SessionFactory. A replacement for NHibernate's SchemaExport class, to be invoked on application setup. Fetch the LocalSessionFactoryBean itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via LocalSessionFactoryObject lsfb = (LocalSessionFactoryObject) ctx.GetObject("mySessionFactory");.

Uses the SessionFactory that this bean generates for accessing a ADO.NET connection to perform the script.

Execute schema creation script, determined by the Configuration object used for creating the SessionFactory. A replacement for NHibernate's SchemaExport class, to be invoked on application setup. Fetch the LocalSessionFactoryObject itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via LocalSessionFactoryObject lsfo = (LocalSessionFactoryObject) ctx.GetObject("mySessionFactory");.

Uses the SessionFactory that this bean generates for accessing a ADO.NET connection to perform the script.

Execute schema update script, determined by the Configuration object used for creating the SessionFactory. A replacement for NHibernate's SchemaUpdate class, for automatically executing schema update scripts on application startup. Can also be invoked manually. Fetch the LocalSessionFactoryObject itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via LocalSessionFactoryObject lsfo = (LocalSessionFactoryObject) ctx.GetObject("mySessionFactory");.

Uses the SessionFactory that this bean generates for accessing a ADO.NET connection to perform the script.

Execute the given schema script on the given ADO.NET Connection. Note that the default implementation will log unsuccessful statements and continue to execute. Override the ExecuteSchemaStatement method to treat failures differently. The connection to use. The SQL statement to execute. Execute the given schema SQL on the given ADO.NET command. Note that the default implementation will log unsuccessful statements and continue to execute. Override this method to treat failures differently. Subclasses can override this method to perform custom initialization of the SessionFactory instance, creating it via the given Configuration object that got prepared by this LocalSessionFactoryObject.

The default implementation invokes Configuration's BuildSessionFactory. A custom implementation could prepare the instance in a specific way, or use a custom ISessionFactory subclass.

The ISessionFactory instance. Implementation of the PersistenceExceptionTranslator interface, as autodetected by Spring's PersistenceExceptionTranslationPostProcessor. Converts the exception if it is a HibernateException; else returns null to indicate an unknown exception. translate the given exception thrown by a persistence framework to a corresponding exception from Spring's generic DataAccessException hierarchy, if possible. The exception thrown. the corresponding DataAccessException (or null if the exception could not be translated. Convert the given HibernateException to an appropriate exception from the Spring's DAO Exception hierarchy. Will automatically apply a specified IAdoExceptionTranslator to a Hibernate ADOException, else rely on Hibernate's default translation. The Hibernate exception that occured. A corresponding DataAccessException Converts the ADO.NET access exception to an appropriate exception from the org.springframework.dao hierarchy. Can be overridden in subclasses. ADOException that occured, wrapping underlying ADO.NET exception. the corresponding DataAccessException instance Setting the Application Context determines were resources are loaded from Gets or sets the to use for loading mapping assemblies etc. Sets the assemblies to load that contain mapping files. The mapping assemblies. Sets the hibernate configuration files to load, i.e. hibernate.cfg.xml. Sets the locations of Spring IResources that contain mapping files. The location of mapping resources. Return the Configuration object used to build the SessionFactory. Allows access to configuration metadata stored there (rarely needed). The hibernate configuration. Set NHibernate configuration properties, like "hibernate.dialect". The hibernate properties.

Can be used to override values in a NHibernate XML config file, or to specify all necessary properties locally.

Note: Do not specify a transaction provider here when using Spring-driven transactions. It is also advisable to omit connection provider settings and use a Spring-set IDbProvider instead.

Get or set the DataSource to be used by the SessionFactory. The db provider. If set, this will override corresponding settings in Hibernate properties. Note: If this is set, the Hibernate settings should not define a connection string (hibernate.connection.connection_string) to avoid meaningless double configuration. Gets or sets a value indicating whether to expose a transaction aware session factory. true if want to expose transaction aware session factory; otherwise, false. Set a NHibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this factory.

Such an interceptor can either be set at the SessionFactory level, i.e. on LocalSessionFactoryObject, or at the Session level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryObject or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions.

 Set a Hibernate NamingStrategy for the SessionFactory, determining the physical column and table names given the info in the mapping document. Specify the Hibernate type definitions to register with the SessionFactory, as Spring IObjectDefinition instances. This is an alternative to specifying <typedef> elements in Hibernate mapping files.

Unfortunately, Hibernate itself does not define a complete object that represents a type definition, hence the need for Spring's TypeDefinitionBean.

@see TypeDefinitionBean @see org.hibernate.cfg.Mappings#addTypeDef(String, String, java.util.Properties) Specify the NHibernate FilterDefinitions to register with the SessionFactory. This is an alternative to specifying <filter-def> elements in Hibernate mapping files. Typically, the passed-in FilterDefinition objects will have been defined as Spring FilterDefinitionFactoryBeans, probably as inner beans within the LocalSessionFactoryObject definition. Specify the cache strategies for entities (persistent classes or named entities). This configuration setting corresponds to the <class-cache> entry in the "hibernate.cfg.xml" configuration format.

For example: 

            <property name="entityCacheStrategies">
              <props>
                <prop key="MyCompany.Customer">read-write</prop>
                <prop key="MyCompany.Product">read-only,myRegion</prop>
              </props>
            </property>

 Specify the cache strategies for persistent collections (with specific roles). This configuration setting corresponds to the <collection-cache> entry in the "hibernate.cfg.xml" configuration format.

For example: 

            <property name="CollectionCacheStrategies">
              <props>
                <prop key="MyCompany.Order.Items">read-write</prop>
                <prop key="MyCompany.Product.Categories">read-only,myRegion</prop>
              </props>
            </property>

 Specify the NHibernate event listeners to register, with listener types as keys and listener objects as values.

Instead of a single listener object, you can also pass in a list or set of listeners objects as value.

listener objects as values See the NHibernate documentation for further details on listener types and associated listener interfaces. Set whether to execute a schema update after SessionFactory initialization.

For details on how to make schema update scripts work, see the NHibernate documentation, as this class leverages the same schema update script support in as NHibernate's own SchemaUpdate tool.

Set the ADO.NET exception translator for this instance. Applied to System.Data.Common.DbException (or provider specific exception type in .NET 1.1) thrown by callback code, be it direct DbException or wrapped Hibernate ADOExceptions.

The default exception translator is either a ErrorCodeExceptionTranslator if a DbProvider is available, or a FalbackExceptionTranslator otherwise

The ADO exception translator. Sets custom byte code provider implementation to be used. This corresponds to setting the property before NHibernate session factory configuration. Return the type or subclass. The type created by this factory Returns true true Subclasses can override this method to perform custom initialization of the SessionFactory instance, creating it via the given Configuration object that got prepared by this LocalSessionFactoryObject.

The default implementation invokes Configuration's BuildSessionFactory. A custom implementation could prepare the instance in a specific way, or use a custom ISessionFactory subclass.

The ISessionFactory instance. PostProcessConfiguration DelegatingSessionFactory class PlatformTransactionManager implementation for a single Hibernate SessionFactory. Binds a Hibernate Session from the specified factory to the thread, potentially allowing for one thread Session per factory SessionFactoryUtils and HibernateTemplate are aware of thread-bound Sessions and participate in such transactions automatically. Using either of those is required for Hibernate access code that needs to support this transaction handling mechanism. Supports custom isolation levels at the start of the transaction , and timeouts that get applied as appropriate Hibernate query timeouts. To support the latter, application code must either use HibernateTemplate (which by default applies the timeouts) or call SessionFactoryUtils.applyTransactionTimeout for each created Hibernate Query object. Note that you can specify a Spring IDbProvider instance which if shared with a corresponding instance of AdoTemplate will allow for mixing ADO.NET/NHibernate operations within a single transaction. Mark Pollack (.NET) Just needed for entityInterceptorBeanName. Initializes a new instance of the class. Initializes a new instance of the class. The session factory. Return the current transaction object. The current transaction object. If transaction support is not available. In the case of lookup or system errors.

This implemenation unbinds the SessionFactory and DbProvider from thread local storage and closes the ISession.

Called after and execution on any outcome.

Should not throw any exceptions but just issue warnings on errors.

Invoked by an after it has injected all of an object's dependencies.

This method allows the object instance to perform the kind of initialization only possible when all of it's dependencies have been injected (set), and to throw an appropriate exception in the event of misconfiguration.

Please do consult the class level documentation for the interface for a description of exactly when this method is invoked. In particular, it is worth noting that the and callbacks will have been invoked prior to this method being called.

In the event of misconfiguration (such as the failure to set a required property) or if initialization fails. Gets or sets the db provider. The db provider. Gets or sets a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. When getting, return the current Hibernate entity interceptor, or null if none. The entity interceptor. Resolves an entity interceptor object name via the object factory, if necessary. Will get applied to any new Session created by this transaction manager. Such an interceptor can either be set at the SessionFactory level, i.e. on LocalSessionFactoryObject, or at the Session level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryObject or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions. If object factory is null and need to get entity interceptor via object name. Sets the object name of a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. The name of the entity interceptor object. Will get applied to any new Session created by this transaction manager.

Requires the object factory to be known, to be able to resolve the object name to an interceptor instance on session creation. Typically used for prototype interceptors, i.e. a new interceptor instance per session.

Can also be used for shared interceptor instances, but it is recommended to set the interceptor reference directly in such a scenario.

Gets or sets the ADO.NET exception translator for this transaction manager. Applied to ADO.NET Exceptions (wrapped by Hibernate's ADOException) The ADO exception translator. Gets the default IAdoException translator, lazily creating it if nece The default IAdoException translator. Gets or sets the SessionFactory that this instance should manage transactions for.

Set whether to autodetect a ADO.NET connection used by the Hibernate SessionFactory, if set via LocalSessionFactoryObject's DbProvider. Default is "true". true if [autodetect data source]; otherwise, false.

Can be turned off to deliberately ignore an available IDbProvider, to not expose Hibernate transactions as ADO.NET transactions for that IDbProvider.

The object factory just needs to be known for resolving entity interceptor It does not need to be set for any other mode of operation. Owning (may not be ). The object can immediately call methods on the factory. Return whether the transaction is internally marked as rollback-only. True of the transaction is marked as rollback-only.

Requires a SessionFactory to be set, providing a HibernateTemplate based on it to subclasses. Can alternatively be initialized directly with a HibernateTemplate, to reuse the latter's settings such as the SessionFactory, exception translator, flush mode, etc This base call is mainly intended for HibernateTemplate usage. This class will create its own HibernateTemplate if only a SessionFactory is passed in. The "allowCreate" flag on that HibernateTemplate will be "true" by default. A custom HibernateTemplate instance can be used through overriding CreateHibernateTemplate. Mark Pollack (.NET) Initializes a new instance of the class. Create a HibernateTemplate for the given ISessionFactory. Only invoked if populating the DAO with a ISessionFactory reference!

Can be overridden in subclasses to provide a HibernateTemplate instance with different configuration, or a custom HibernateTemplate subclass.

Check if the hibernate template property has been set. Get a Hibernate Session, either from the current transaction or a new one. The latter is only allowed if "allowCreate" is true. Note that this is not meant to be invoked from HibernateTemplate code but rather just in plain Hibernate code. Either rely on a thread-bound Session (via HibernateInterceptor), or use it in combination with ReleaseSession. In general, it is recommended to use HibernateTemplate, either with the provided convenience operations or with a custom HibernateCallback that provides you with a Session to work on. HibernateTemplate will care for all resource management and for proper exception conversion. if a non-transactional Session should be created when no transactional Session can be found for the current thread Hibernate session. If the Session couldn't be created if no thread-bound Session found and allowCreate false Convert the given HibernateException to an appropriate exception from the org.springframework.dao hierarchy. Will automatically detect wrapped ADO.NET Exceptions and convert them accordingly. HibernateException that occured. The corresponding DataAccessException instance The default implementation delegates to SessionFactoryUtils and convertAdoAccessException. Can be overridden in subclasses. Close the given Hibernate Session, created via this DAO's SessionFactory, if it isn't bound to the thread. Typically used in plain Hibernate code, in combination with the Session property and ConvertHibernateAccessException. The session to close. Gets or sets the hibernate template. Set the HibernateTemplate for this DAO explicitly, as an alternative to specifying a SessionFactory. The hibernate template. Gets or sets the session factory to be used by this DAO. Will automatically create a HibernateTemplate for the given SessionFactory. The session factory. Get a Hibernate Session, either from the current transaction or a new one. The latter is only allowed if the "allowCreate" setting of this object's HibernateTemplate is true.

Note that this is not meant to be invoked from HibernateTemplate code but rather just in plain Hibernate code. Use it in combination with ReleaseSession.

In general, it is recommended to use HibernateTemplate, either with the provided convenience operations or with a custom HibernateCallback that provides you with a Session to work on. HibernateTemplate will care for all resource management and for proper exception conversion.

The Hibernate session. Provide support for the open session in view pattern for lazily loaded hibernate objects used in ASP.NET pages. jjx: http://forum.springframework.net/member.php?u=29 Mark Pollack (.NET) Erich Eichinger Harald Radi Implementation of SessionScope that associates a single session within the using scope. It is recommended to be used in the following type of scenario: using (new SessionScope()) { ... do multiple operation, possibly in multiple transactions. } At the end of "using", the session is automatically closed. All transactions within the scope use the same session, if you are using Spring's HibernateTemplate or using Spring's implementation of NHibernate 1.2's ICurrentSessionContext interface. It is assumed that the session factory object name is called "SessionFactory". In case that you named the object in different way you can specify your can specify it in the application settings using the key Spring.Data.NHibernate.Support.SessionScope.SessionFactoryObjectName. Values for EntityInterceptorObjectName and SingleSessionMode can be specified similarly. Note: The session is managed on a per thread basis on the thread that opens the scope instance.

Typically used to implement data access or business logic services that use NHibernate within their implementation but are Hibernate-agnostic in their interface. The latter or code calling the latter only have to deal with domain objects.

The central method is Execute supporting Hibernate access code implementing the HibernateCallback interface. It provides NHibernate Session handling such that neither the IHibernateCallback implementation nor the calling code needs to explicitly care about retrieving/closing NHibernate Sessions, or handling Session lifecycle exceptions. For typical single step actions, there are various convenience methods (Find, Load, SaveOrUpdate, Delete).

Can be used within a service implementation via direct instantiation with a ISessionFactory reference, or get prepared in an application context and given to services as an object reference. Note: The ISessionFactory should always be configured as an object in the application context, in the first case given to the service directly, in the second case to the prepared template.

This class can be considered as direct alternative to working with the raw Hibernate Session API (through SessionFactoryUtils.Session).

LocalSessionFactoryObject is the preferred way of obtaining a reference to a specific NHibernate ISessionFactory.

ADOException that occured, wrapping underlying ADO.NET exception. the corresponding DataAccessException instance Converts the ADO.NET access exception to an appropriate exception from the org.springframework.dao hierarchy. Can be overridden in subclasses. Note that a direct SQLException can just occur when callback code performs direct ADO.NET access via ISession.Connection(). The ADO.NET exception. The corresponding DataAccessException instance Prepare the given IQuery object, applying cache settings and/or a transaction timeout. The query object to prepare. Apply the given name parameter to the given Query object. The query object. Name of the parameter The value of the parameter The NHibernate type of the parameter (or null if none specified) Prepare the given Criteria object, applying cache settings and/or a transaction timeout. Note that for NHibernate 1.2 this only works if the implementation is of the type CriteriaImpl, which should generally be the case. The SetFetchSize method is not available on the ICriteria interface This is a no-op for NHibernate 1.0.x since the SetFetchSize method is not on the ICriteria interface and the implementation class is has internal access. To remove the method completely for Spring's NHibernate 1.0 support while reusing code for NHibernate 1.2 would not be possible. So now this ineffectual operation is left in tact for NHibernate 1.0.2 support. The criteria object to prepare Ensure SessionFactory is not null If SessionFactory property is null. Gets or sets if a new Session should be created when no transactional Session can be found for the current thread. true if allowed to create non-transaction session; otherwise, false.

HibernateTemplate is aware of a corresponding Session bound to the current thread, for example when using HibernateTransactionManager. If allowCreate is true, a new non-transactional Session will be created if none found, which needs to be closed at the end of the operation. If false, an InvalidOperationException will get thrown in this case.

Gets or sets a value indicating whether to always use a new Hibernate Session for this template. true if always use new session; otherwise, false.

Default is "false"; if activated, all operations on this template will work on a new NHibernate ISession even in case of a pre-bound ISession (for example, within a transaction).

Within a transaction, a new NHibernate ISession used by this template will participate in the transaction through using the same ADO.NET Connection. In such a scenario, multiple Sessions will participate in the same database transaction.

Turn this on for operations that are supposed to always execute independently, without side effects caused by a shared NHibernate ISession.

Set whether to expose the native Hibernate Session to IHibernateCallback code. Default is "false": a Session proxy will be returned, suppressing close calls and automatically applying query cache settings and transaction timeouts. true if expose native session; otherwise, false. Gets or sets the template flush mode. Default is Auto. Will get applied to any new ISession created by the template. The template flush mode. Gets or sets the entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new ISession created by this object.

Such an interceptor can either be set at the ISessionFactory level, i.e. on LocalSessionFactoryObject, or at the ISession level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryObject or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions.

The interceptor. Set the object name of a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this transaction manager.

Requires the object factory to be known, to be able to resolve the object name to an interceptor instance on session creation. Typically used for prototype interceptors, i.e. a new interceptor instance per session.

Can also be used for shared interceptor instances, but it is recommended to set the interceptor reference directly in such a scenario.

The name of the entity interceptor in the object factory/application context. Gets or sets the session factory that should be used to create NHibernate ISessions. The session factory. Set the object factory instance. The object factory instance. Gets or sets a value indicating whether to cache all queries executed by this template. If this is true, all IQuery and ICriteria objects created by this template will be marked as cacheable (including all queries through find methods).

To specify the query region to be used for queries cached by this template, set the QueryCacheRegion property.

true if cache queries; otherwise, false. Gets or sets the name of the cache region for queries executed by this template. If this is specified, it will be applied to all IQuery and ICriteria objects created by this template (including all queries through find methods).

The cache region will not take effect unless queries created by this template are configured to be cached via the CacheQueries property.

The query cache region. Gets or sets the fetch size for this HibernateTemplate. The size of the fetch. This is important for processing large result sets: Setting this higher than the default value will increase processing speed at the cost of memory consumption; setting this lower can avoid transferring row data that will never be read by the application.

Default is 0, indicating to use the driver's default.

 Gets or sets the maximum number of rows for this HibernateTemplate. The max results. This is important for processing subsets of large result sets, avoiding to read and hold the entire result set in the database or in the ADO.NET driver if we're never interested in the entire result in the first place (for example, when performing searches that might return a large number of matches).

Default is 0, indicating to use the driver's default.

 Set the ADO.NET exception translator for this instance. Applied to System.Data.Common.DbException (or provider specific exception type in .NET 1.1) thrown by callback code, be it direct DbException or wrapped Hibernate ADOExceptions.

The default exception translator is either a ErrorCodeExceptionTranslator if a DbProvider is available, or a FalbackExceptionTranslator otherwise

The ADO exception translator. Gets a Session for use by this template. The session. - Returns a new Session in case of "alwaysUseNewSession" (using the same ADO.NET connection as a transaction Session, if applicable) - a pre-bound Session in case of "AllowCreate" is set to false (not the default) - or a pre-bound Session or new Session if no transactional or other pre-bound Session exists. Helper class to determine if the FlushMode enumeration was changed from its default value Initializes a new instance of the class. Initializes a new instance of the class. The flush mode. Gets or sets a value indicating whether the FlushMode property was set.. true if FlushMode was set; otherwise, false. Gets or sets the FlushMode. The FlushMode. Interface that specifies a basic set of Hibernate operations. Implemented by HibernateTemplate. Not often used, but a useful option to enhance testability, as it can easily be mocked or stubbed.

If there is no persistent instance currently associated with the session, it will be loaded. Return the persistent instance. If the given instance is unsaved, save a copy of and return it as a newly persistent instance. The given instance does not become associated with the session.

Default is "false"; if activated, all operations on this template will work on a new NHibernate ISession even in case of a pre-bound ISession (for example, within a transaction).

Within a transaction, a new NHibernate ISession used by this template will participate in the transaction through using the same ADO.NET Connection. In such a scenario, multiple Sessions will participate in the same database transaction.

Turn this on for operations that are supposed to always execute independently, without side effects caused by a shared NHibernate ISession.

Gets or sets the template flush mode. Default is Auto. Will get applied to any new ISession created by the template. The template flush mode. Gets or sets the entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new ISession created by this object.

Such an interceptor can either be set at the ISessionFactory level, i.e. on LocalSessionFactoryObject, or at the ISession level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryObject or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions.

The interceptor. If object factory is not set and need to retrieve entity interceptor by name. Gets or sets the name of the cache region for queries executed by this template. If this is specified, it will be applied to all IQuery and ICriteria objects created by this template (including all queries through find methods).

The cache region will not take effect unless queries created by this template are configured to be cached via the CacheQueries property.

The query cache region. Gets or sets a value indicating whether to cache all queries executed by this template. If this is true, all IQuery and ICriteria objects created by this template will be marked as cacheable (including all queries through find methods).

To specify the query region to be used for queries cached by this template, set the QueryCacheRegion property.

true if cache queries; otherwise, false. Gets or sets the maximum number of rows for this HibernateTemplate. The max results. This is important for processing subsets of large result sets, avoiding to read and hold the entire result set in the database or in the ADO.NET driver if we're never interested in the entire result in the first place (for example, when performing searches that might return a large number of matches).

Default is 0, indicating to use the driver's default.

 Set whether to expose the native Hibernate Session to IHibernateCallback code. Default is "false": a Session proxy will be returned, suppressing close calls and automatically applying query cache settings and transaction timeouts. true if expose native session; otherwise, false. Gets or sets whether to check that the Hibernate Session is not in read-only mode in case of write operations (save/update/delete). true if check that the Hibernate Session is not in read-only mode in case of write operations; otherwise, false. Default is "true", for fail-fast behavior when attempting write operations within a read-only transaction. Turn this off to allow save/update/delete on a Session with flush mode NEVER. Set the object name of a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this transaction manager.

Requires the object factory to be known, to be able to resolve the object name to an interceptor instance on session creation. Typically used for prototype interceptors, i.e. a new interceptor instance per session.

Can also be used for shared interceptor instances, but it is recommended to set the interceptor reference directly in such a scenario.

The name of the entity interceptor in the object factory/application context. Set the object factory instance. The object factory instance Gets or sets the session factory that should be used to create NHibernate ISessions. The session factory. Gets or sets the fetch size for this HibernateTemplate. The size of the fetch. This is important for processing large result sets: Setting this higher than the default value will increase processing speed at the cost of memory consumption; setting this lower can avoid transferring row data that will never be read by the application.

Default is 0, indicating to use the driver's default.

 Gets or sets the proxy factory. This may be useful to set if you create many instances of HibernateTemplate and/or HibernateDaoSupport. This allows the same ProxyFactory implementation to be used thereby limiting the number of dynamic proxy types created in the temporary assembly, which are never garbage collected due to .NET runtime semantics. The proxy factory. Set the ADO.NET exception translator for this instance. Applied to System.Data.Common.DbException (or provider specific exception type in .NET 1.1) thrown by callback code, be it direct DbException or wrapped Hibernate ADOExceptions.

The default exception translator is either a ErrorCodeExceptionTranslator if a DbProvider is available, or a FalbackExceptionTranslator otherwise

The ADO exception translator. Callback interface for NHibernate code. To be used with HibernateTemplate execute method. The typical implementation will call Session.load/find/save/update to perform some operations on persistent objects. Mark Pollack (.NET) Gets called by HibernateTemplate with an active Hibernate Session. Does not need to care about activating or closing the Session, or handling transactions.

PlatformTransactionManager implementation for a single Hibernate SessionFactory. Binds a Hibernate Session from the specified factory to the thread, potentially allowing for one thread Session per factory SessionFactoryUtils and HibernateTemplate are aware of thread-bound Sessions and participate in such transactions automatically. Using either of those is required for Hibernate access code that needs to support this transaction handling mechanism. Supports custom isolation levels at the start of the transaction , and timeouts that get applied as appropriate Hibernate query timeouts. To support the latter, application code must either use HibernateTemplate (which by default applies the timeouts) or call SessionFactoryUtils.applyTransactionTimeout for each created Hibernate Query object. Note that you can specify a Spring IDbProvider instance which if shared with a corresponding instance of AdoTemplate will allow for mixing ADO.NET/NHibernate operations within a single transaction. Mark Pollack (.NET) Just needed for entityInterceptorBeanName. Initializes a new instance of the class. Initializes a new instance of the class. The session factory. Return the current transaction object. The current transaction object. If transaction support is not available. In the case of lookup or system errors.

Begin a new transaction with the given transaction definition. Transaction object returned by . instance, describing propagation behavior, isolation level, timeout etc. Does not have to care about applying the propagation behavior, as this has already been handled by this abstract manager. In the case of creation or system errors. Suspend the resources of the current transaction. Transaction object returned by . An object that holds suspended resources (will be kept unexamined for passing it into .) Transaction synchronization will already have been suspended. If suspending is not supported by the transaction manager implementation. in case of system errors. Resume the resources of the current transaction. Transaction object returned by .

This implemenation unbinds the SessionFactory and DbProvider from thread local storage and closes the ISession.

Called after and execution on any outcome.

Should not throw any exceptions but just issue warnings on errors.

Invoked by an after it has injected all of an object's dependencies.

This method allows the object instance to perform the kind of initialization only possible when all of it's dependencies have been injected (set), and to throw an appropriate exception in the event of misconfiguration.

Please do consult the class level documentation for the interface for a description of exactly when this method is invoked. In particular, it is worth noting that the and callbacks will have been invoked prior to this method being called.

In the event of misconfiguration (such as the failure to set a required property) or if initialization fails. Gets or sets the db provider. The db provider. Gets or sets a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. When getting, return the current Hibernate entity interceptor, or null if none. The entity interceptor. Resolves an entity interceptor object name via the object factory, if necessary. Will get applied to any new Session created by this transaction manager. Such an interceptor can either be set at the SessionFactory level, i.e. on LocalSessionFactoryObject, or at the Session level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryObject or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions. If object factory is null and need to get entity interceptor via object name. Sets the object name of a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. The name of the entity interceptor object. Will get applied to any new Session created by this transaction manager.

Requires the object factory to be known, to be able to resolve the object name to an interceptor instance on session creation. Typically used for prototype interceptors, i.e. a new interceptor instance per session.

Can also be used for shared interceptor instances, but it is recommended to set the interceptor reference directly in such a scenario.

Gets or sets the ADO.NET exception translator for this transaction manager. Applied to ADO.NET Exceptions (wrapped by Hibernate's ADOException) The ADO exception translator. Gets the default IAdoException translator, lazily creating it if nece The default IAdoException translator. Gets or sets the SessionFactory that this instance should manage transactions for. The session factory. Gets the resource factory that this transaction manager operates on, For the HibenratePlatformTransactionManager this the SessionFactory The SessionFactory. Set whether to autodetect a ADO.NET connection used by the Hibernate SessionFactory, if set via LocalSessionFactoryObject's DbProvider. Default is "true". true if [autodetect data source]; otherwise, false.

Can be turned off to deliberately ignore an available IDbProvider, to not expose Hibernate transactions as ADO.NET transactions for that IDbProvider.

The object factory just needs to be known for resolving entity interceptor It does not need to be set for any other mode of operation. Owning (may not be ). The object can immediately call methods on the factory. Return whether the transaction is internally marked as rollback-only. True of the transaction is marked as rollback-only. Enumeration for the various Hibernate flush modes. Mark Pollack (.NET) Never flush is a good strategy for read-only units of work. Hibernate will not track and look for changes in this case, avoiding any overhead of modification detection.

In case of an existing ISession, TemplateFlushMode.Never will turn the hibenrate flush mode to FlushMode.Never for the scope of the current operation, resetting the previous flush mode afterwards.

Automatic flushing is the default mode for a Hibernate Session. A session will get flushed on transaction commit, and on certain find operations that might involve already modified instances, but not after each unit of work like with eager flushing.

In case of an existing Session, TemplateFlushMode.Auto will participate in the existing flush mode, not modifying it for the current operation. This in particular means that this setting will not modify an existing hibernate flush mode FlushMode.Never, in contrast to TemplateFlushMode.Eager.

Eager flushing leads to immediate synchronization with the database, even if in a transaction. This causes inconsistencies to show up and throw a respective exception immediately, and ADO access code that participates in the same transaction will see the changes as the database is already aware of them then. But the drawbacks are:
  • additional communication roundtrips with the database, instead of a single batch at transaction commit;
  • the fact that an actual database rollback is needed if the Hibernate transaction rolls back (due to already submitted SQL statements).

In case of an existing Session, TemplateFlushMode.Eager will turn the NHibernate flush mode to FlushMode.Auto for the scope of the current operation and issue a flush at the end, resetting the previous flush mode afterwards.

Flushing at commit only is intended for units of work where no intermediate flushing is desired, not even for find operations that might involve already modified instances.

In case of an existing Session, TemplateFlushMode.Commit will turn the NHibernate flush mode to FlushMode.Commit for the scope of the current operation, resetting the previous flush mode afterwards. The only exception is an existing flush mode FlushMode.Never, which will not be modified through this setting.

Gets called by HibernateTemplate with an active Hibernate Session. Does not need to care about activating or closing the Session, or handling transactions.

Allows for returning an IList of result objects created within the callback. Note that there's special support for single step actions: see HibernateTemplate.find etc.

The type of result object Sree Nivask (.NET) Convenient super class for Hibernate data access objects. Requires a SessionFactory to be set, providing a HibernateTemplate based on it to subclasses. Can alternatively be initialized directly with a HibernateTemplate, to reuse the latter's settings such as the SessionFactory, exception translator, flush mode, etc This base call is mainly intended for HibernateTemplate usage. This class will create its own HibernateTemplate if only a SessionFactory is passed in. The "allowCreate" flag on that HibernateTemplate will be "true" by default. A custom HibernateTemplate instance can be used through overriding CreateHibernateTemplate. Sree Nivask (.NET) Mark Pollack (.NET) Initializes a new instance of the class. Create a HibernateTemplate for the given ISessionFactory. Only invoked if populating the DAO with a ISessionFactory reference!

Can be overridden in subclasses to provide a HibernateTemplate instance with different configuration, or a custom HibernateTemplate subclass.

The new HibernateTemplate instance Check if the hibernate template property has been set. If HibernateTemplate property is null. Get a Hibernate Session, either from the current transaction or a new one. The latter is only allowed if "allowCreate" is true. Note that this is not meant to be invoked from HibernateTemplate code but rather just in plain Hibernate code. Either rely on a thread-bound Session (via HibernateInterceptor), or use it in combination with ReleaseSession. In general, it is recommended to use HibernateTemplate, either with the provided convenience operations or with a custom HibernateCallback that provides you with a Session to work on. HibernateTemplate will care for all resource management and for proper exception conversion. if a non-transactional Session should be created when no transactional Session can be found for the current thread Hibernate session. If the Session couldn't be created if no thread-bound Session found and allowCreate false Convert the given HibernateException to an appropriate exception from the org.springframework.dao hierarchy. Will automatically detect wrapped ADO.NET Exceptions and convert them accordingly. HibernateException that occured. The corresponding DataAccessException instance The default implementation delegates to SessionFactoryUtils and convertAdoAccessException. Can be overridden in subclasses. Close the given Hibernate Session, created via this DAO's SessionFactory, if it isn't bound to the thread. Typically used in plain Hibernate code, in combination with the Session property and ConvertHibernateAccessException. The session to close. Gets or sets the hibernate template. Set the HibernateTemplate for this DAO explicitly, as an alternative to specifying a SessionFactory. The hibernate template. Gets or sets the session factory to be used by this DAO. Will automatically create a HibernateTemplate for the given SessionFactory. The session factory. Get a Hibernate Session, either from the current transaction or a new one. The latter is only allowed if the "allowCreate" setting of this object's HibernateTemplate is true.

Note that this is not meant to be invoked from HibernateTemplate code but rather just in plain Hibernate code. Use it in combination with ReleaseSession.

In general, it is recommended to use HibernateTemplate, either with the provided convenience operations or with a custom HibernateCallback that provides you with a Session to work on. HibernateTemplate will care for all resource management and for proper exception conversion.

The Hibernate session. Gets called by HibernateTemplate with an active Hibernate Session. Does not need to care about activating or closing the Session, or handling transactions.

Allows for returning the result object created within the callback. Note that there's special support for single step actions: see HibernateTemplate.find etc.

The type of result object Sree Nivask (.NET) Generic version of the Helper class that simplifies NHibernate data access code

Typically used to implement data access or business logic services that use NHibernate within their implementation but are Hibernate-agnostic in their interface. The latter or code calling the latter only have to deal with domain objects.

The central method is Execute() supporting Hibernate access code which implements the HibernateCallback interface. It provides NHibernate Session handling such that neither the IHibernateCallback implementation nor the calling code needs to explicitly care about retrieving/closing NHibernate Sessions, or handling Session lifecycle exceptions. For typical single step actions, there are various convenience methods (Find, Load, SaveOrUpdate, Delete).

Can be used within a service implementation via direct instantiation with a ISessionFactory reference, or get prepared in an application context and given to services as an object reference. Note: The ISessionFactory should always be configured as an object in the application context, in the first case given to the service directly, in the second case to the prepared template.

This class can be considered as a direct alternative to working with the raw Hibernate Session API (through SessionFactoryUtils.Session).

LocalSessionFactoryObject is the preferred way of obtaining a reference to a specific NHibernate ISessionFactory.

Sree Nivask (.NET) Mark Pollack (.NET) Interface that specifies a basic set of Hibernate operations. Implemented by HibernateTemplate. Not often used, but a useful option to enhance testability, as it can easily be mocked or stubbed.

Provides HibernateTemplate's data access methods that mirror various Session methods. See the NHibernate ISession documentation for details on those methods.

Gets or sets if a new Session should be created when no transactional Session can be found for the current thread. true if allowed to create non-transaction session; otherwise, false.

HibernateTemplate is aware of a corresponding Session bound to the current thread, for example when using HibernateTransactionManager. If allowCreate is true, a new non-transactional Session will be created if none found, which needs to be closed at the end of the operation. If false, an InvalidOperationException will get thrown in this case.

Gets or sets a value indicating whether to always use a new Hibernate Session for this template. true if always use new session; otherwise, false.

Default is "false"; if activated, all operations on this template will work on a new NHibernate ISession even in case of a pre-bound ISession (for example, within a transaction).

Within a transaction, a new NHibernate ISession used by this template will participate in the transaction through using the same ADO.NET Connection. In such a scenario, multiple Sessions will participate in the same database transaction.

Turn this on for operations that are supposed to always execute independently, without side effects caused by a shared NHibernate ISession.

Set whether to expose the native Hibernate Session to IHibernateCallback code. Default is "false": a Session proxy will be returned, suppressing close calls and automatically applying query cache settings and transaction timeouts. true if expose native session; otherwise, false. Gets or sets the template flush mode. Default is Auto. Will get applied to any new ISession created by the template. The template flush mode. Gets or sets the entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new ISession created by this object.

Such an interceptor can either be set at the ISessionFactory level, i.e. on LocalSessionFactoryObject, or at the ISession level, i.e. on HibernateTemplate, HibernateInterceptor, and HibernateTransactionManager. It's preferable to set it on LocalSessionFactoryObject or HibernateTransactionManager to avoid repeated configuration and guarantee consistent behavior in transactions.

The interceptor. Set the object name of a Hibernate entity interceptor that allows to inspect and change property values before writing to and reading from the database. Will get applied to any new Session created by this transaction manager.

Requires the object factory to be known, to be able to resolve the object name to an interceptor instance on session creation. Typically used for prototype interceptors, i.e. a new interceptor instance per session.

Can also be used for shared interceptor instances, but it is recommended to set the interceptor reference directly in such a scenario.

The name of the entity interceptor in the object factory/application context. Gets or sets the session factory that should be used to create NHibernate ISessions. The session factory. Set the object factory instance. The object factory instance Gets or sets a value indicating whether to cache all queries executed by this template. If this is true, all IQuery and ICriteria objects created by this template will be marked as cacheable (including all queries through find methods).

To specify the query region to be used for queries cached by this template, set the QueryCacheRegion property.

true if cache queries; otherwise, false. Gets or sets the name of the cache region for queries executed by this template. If this is specified, it will be applied to all IQuery and ICriteria objects created by this template (including all queries through find methods).

The cache region will not take effect unless queries created by this template are configured to be cached via the CacheQueries property.

The query cache region. Gets or sets the fetch size for this HibernateTemplate. The size of the fetch. This is important for processing large result sets: Setting this higher than the default value will increase processing speed at the cost of memory consumption; setting this lower can avoid transferring row data that will never be read by the application.

Default is 0, indicating to use the driver's default.

 Gets or sets the maximum number of rows for this HibernateTemplate. The max results. This is important for processing subsets of large result sets, avoiding to read and hold the entire result set in the database or in the ADO.NET driver if we're never interested in the entire result in the first place (for example, when performing searches that might return a large number of matches).

Default is 0, indicating to use the driver's default.

 Set the ADO.NET exception translator for this instance. Applied to System.Data.Common.DbException (or provider specific exception type in .NET 1.1) thrown by callback code, be it direct DbException or wrapped Hibernate ADOExceptions.

The default exception translator is either a ErrorCodeExceptionTranslator if a DbProvider is available, or a FalbackExceptionTranslator otherwise

The ADO exception translator. Gets the classic hibernate template for access to non-generic methods. The classic hibernate template. Gets or sets the proxy factory. This may be useful to set if you create many instances of HibernateTemplate and/or HibernateDaoSupport. This allows the same ProxyFactory implementation to be used thereby limiting the number of dynamic proxy types created in the temporary assembly, which are never garbage collected due to .NET runtime semantics. The proxy factory. Callback interface (Generic version) for NHibernate code. The type of result object To be used with HibernateTemplate execute method. The typical implementation will call Session.load/find/save/update to perform some operations on persistent objects.

Invoked before transaction commit (before ) If the transaction is defined as a read-only transaction.

Can flush transactional sessions to the database.

Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.

Invoked before transaction commit (before ) Can e.g. flush transactional O/R Mapping sessions to the database This callback does not mean that the transaction will actually be commited. A rollback decision can still occur after this method has been called. This callback is rather meant to perform work that's only relevant if a commit still has a chance to happen, such as flushing SQL statements to the database. Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction. (note: do not throw TransactionException subclasses here!) Invoked after transaction commit/rollback. Status according to Can e.g. perform resource cleanup, in this case after transaction completion.

Note that exceptions will get propagated to the commit or rollback caller, although they will not influence the outcome of the transaction.

Return the order value of this object, where a higher value means greater in terms of sorting.
