Class LocalSessionFactoryBean

java.lang.Object
  org.springframework.orm.hibernate.LocalSessionFactoryBean

All Implemented Interfaces:: DisposableBean, FactoryBean, InitializingBean

public class LocalSessionFactoryBean
extends Object
implements FactoryBean, InitializingBean, DisposableBean
extends Object
implements FactoryBean, InitializingBean, DisposableBean

FactoryBean that creates a local Hibernate SessionFactory instance. Behaves like a SessionFactory instance when used as bean reference, e.g. for HibernateTemplate's "sessionFactory" property. Note that switching to JndiObjectFactoryBean is just a matter of configuration!

The typical usage will be to register this as singleton factory (for a certain underlying JDBC DataSource) in an application context, and give bean references to application services that need it.

Configuration settings can either be read from a Hibernate XML file, specified as "configLocation", or completely via this class. A typical local configuration consists of one or more "mappingResources", various "hibernateProperties" (not strictly necessary), and a "dataSource" that the SessionFactory should use. The latter can also be specified via Hibernate properties, but "dataSource" supports any Spring-configured DataSource, instead of relying on Hibernate's own connection providers.

This SessionFactory handling strategy is appropriate for most types of applications, from Hibernate-only single database apps to ones that need distributed transactions. Either HibernateTransactionManager or JtaTransactionManager can be used for transaction demarcation, the latter only being necessary for transactions that span multiple databases.

Registering a SessionFactory with JNDI is only advisable when using Hibernate's JCA Connector, i.e. when the application server cares for initialization. Else, portability is rather limited: Manual JNDI binding isn't supported by some application servers (e.g. Tomcat). Unfortunately, JCA has drawbacks too: Its setup is container-specific and can be tedious.

Note that the JCA Connector's sole major strength is its seamless cooperation with EJB containers and JTA services. If you do not use EJB and initiate your JTA transactions via Spring's JtaTransactionManager, you can get all benefits including distributed transactions and proper transactional JVM-level caching with local SessionFactory setup too - without any configuration hassle like container-specific setup.

Note: Spring's Hibernate support requires Hibernate 2.1 (as of Spring 1.0).

Method Detail

getConfigTimeDataSource

public static DataSource getConfigTimeDataSource()

Return the DataSource for the currently configured Hibernate SessionFactory, to be used by LocalDataSourceConnectionProvoder.

This instance will be set before initialization of the corresponding SessionFactory, and reset immediately afterwards. It is thus only available during configuration.

See Also:: setDataSource(javax.sql.DataSource), LocalDataSourceConnectionProvider

getConfigTimeTransactionManager

public static TransactionManager getConfigTimeTransactionManager()

Return the JTA TransactionManager for the currently configured Hibernate SessionFactory, to be used by LocalTransactionManagerLookup.

This instance will be set before initialization of the corresponding SessionFactory, and reset immediately afterwards. It is thus only available during configuration.

See Also:: setJtaTransactionManager(javax.transaction.TransactionManager), LocalTransactionManagerLookup

getConfigTimeLobHandler

public static LobHandler getConfigTimeLobHandler()

Return the LobHandler for the currently configured Hibernate SessionFactory, to be used by UserType implementations like ClobStringType.

This instance will be set before initialization of the corresponding SessionFactory, and reset immediately afterwards. It is thus only available during configuration.

See Also:: setLobHandler(org.springframework.jdbc.support.lob.LobHandler), ClobStringType, BlobByteArrayType, BlobSerializableType

setConfigLocation

public void setConfigLocation(Resource configLocation)

Set the location of the Hibernate XML config file, for example as classpath resource "classpath:hibernate.cfg.xml".

Note: Can be omitted when all necessary properties and mapping resources are specified locally via this bean.

See Also:: Configuration.configure(java.net.URL)

setMappingResources

public void setMappingResources(String[] mappingResources)

Set Hibernate mapping resources to be found in the class path, like "example.hbm.xml" or "mypackage/example.hbm.xml". Analogous to mapping entries in a Hibernate XML config file. Alternative to the more generic setMappingLocations method.

Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

See Also:: setMappingLocations(org.springframework.core.io.Resource[]), Configuration.addResource(java.lang.String, java.lang.ClassLoader)

setMappingLocations

public void setMappingLocations(Resource[] mappingLocations)

Set locations of Hibernate mapping files, for example as classpath resource "classpath:example.hbm.xml". Supports any resource location via Spring's resource abstraction, for example relative paths like "WEB-INF/mappings/example.hbm.xml" when running in an application context.

Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

See Also:: Configuration.addInputStream(java.io.InputStream)

setMappingJarLocations

public void setMappingJarLocations(Resource[] mappingJarLocations)

Set locations of jar files that contain Hibernate mapping resources, like "WEB-INF/lib/example.hbm.jar".

Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

See Also:: Configuration.addJar(java.io.File)

setMappingDirectoryLocations

public void setMappingDirectoryLocations(Resource[] mappingDirectoryLocations)

Set locations of directories that contain Hibernate mapping resources, like "WEB-INF/mappings".

Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

See Also:: Configuration.addDirectory(java.io.File)

setHibernateProperties

public void setHibernateProperties(Properties hibernateProperties)

Set Hibernate properties, such as "hibernate.dialect".

Can be used to override values in a Hibernate 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 DataSource instead.

See Also:: setDataSource(javax.sql.DataSource)

getHibernateProperties

public Properties getHibernateProperties()

Return the Hibernate properties, if any. Mainly available for configuration through property paths that specify individual keys.

setDataSource

public void setDataSource(DataSource dataSource)

Set the DataSource to be used by the SessionFactory. If set, this will override corresponding settings in Hibernate properties.

Note: If this is set, the Hibernate settings should not define a connection provider to avoid meaningless double configuration.

If using HibernateTransactionManager as transaction strategy, consider proxying your target DataSource with a LazyConnectionDataSourceProxy. This defers fetching of an actual JDBC Connection until the first JDBC Statement gets executed, even within JDBC transactions (as performed by HibernateTransactionManager). Such lazy fetching is particularly beneficial for read-only operations, in particular if the chances of resolving the result in the second-level cache are high.

As JTA and transactional JNDI DataSources already provide lazy enlistment of JDBC Connections, LazyConnectionDataSourceProxy does not add value with JTA (i.e. Spring's JtaTransactionManager) as transaction strategy.

See Also:: setUseTransactionAwareDataSource(boolean), LocalDataSourceConnectionProvider, HibernateTransactionManager, JtaTransactionManager, LazyConnectionDataSourceProxy

setUseTransactionAwareDataSource

public void setUseTransactionAwareDataSource(boolean useTransactionAwareDataSource)

Set whether to use a transaction-aware DataSource for the SessionFactory, i.e. whether to automatically wrap the passed-in DataSource with Spring's TransactionAwareDataSourceProxy.

Default is "false": LocalSessionFactoryBean is usually used with Spring's HibernateTransactionManager or JtaTransactionManager, both of which work nicely on a plain JDBC DataSource. Hibernate Sessions and their JDBC Connections are fully managed by the Hibernate/JTA transaction infrastructure in such a scenario.

If you switch this flag to "true", Spring's Hibernate access will be able to participate in JDBC-based transactions managed outside of Hibernate (for example, by Spring's DataSourceTransactionManager). This can be convenient if you need a different local transaction strategy for another O/R mapping tool, for example, but still want Hibernate access to join into those transactions.

A further benefit of this option is that plain Sessions opened directly via the SessionFactory, outside of Spring's Hibernate support, will still participate in active Spring-managed transactions.

As a further effect, using a transaction-aware DataSource will apply remaining transaction timeouts to all created JDBC Statements. This means that all operations performed by the SessionFactory will automatically participate in Spring-managed transaction timeouts, not just queries. This adds value even for HibernateTransactionManager.

WARNING: Be aware of side effects when using a transaction-aware DataSource in combination with OpenSessionInViewFilter/Interceptor. This combination is only properly supported with HibernateTransactionManager transactions. PROPAGATION_SUPPORTS with HibernateTransactionManager and JtaTransactionManager in general are only supported on Hibernate3, which introduces (optional) aggressive release of Connections.

See Also:: setDataSource(javax.sql.DataSource), TransactionAwareDataSourceProxy, DataSourceTransactionManager, OpenSessionInViewFilter, OpenSessionInViewInterceptor, HibernateTransactionManager, JtaTransactionManager, LocalSessionFactoryBean.setUseTransactionAwareDataSource(boolean)

setJtaTransactionManager

public void setJtaTransactionManager(TransactionManager jtaTransactionManager)

Set the JTA TransactionManager to be used for Hibernate's TransactionManagerLookup. If set, this will override corresponding settings in Hibernate properties. Allows to use a Spring-managed JTA TransactionManager for Hibernate's cache synchronization.

Note: If this is set, the Hibernate settings should not define a transaction manager lookup to avoid meaningless double configuration.

See Also:: LocalTransactionManagerLookup

setLobHandler

public void setLobHandler(LobHandler lobHandler)

Set the LobHandler to be used by the SessionFactory. Will be exposed at config time for UserType implementations.

See Also:: getConfigTimeLobHandler(), UserType, ClobStringType, BlobByteArrayType, BlobSerializableType

setEntityInterceptor

public void setEntityInterceptor(net.sf.hibernate.Interceptor entityInterceptor)

Set 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 factory.

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

See Also:: HibernateAccessor.setEntityInterceptor(net.sf.hibernate.Interceptor), HibernateAccessor.setEntityInterceptor(net.sf.hibernate.Interceptor), HibernateTransactionManager.setEntityInterceptor(net.sf.hibernate.Interceptor), Configuration.setInterceptor(net.sf.hibernate.Interceptor)

setNamingStrategy

public void setNamingStrategy(net.sf.hibernate.cfg.NamingStrategy namingStrategy)

Set a Hibernate NamingStrategy for the SessionFactory, determining the physical column and table names given the info in the mapping document.

See Also:: Configuration.setNamingStrategy(net.sf.hibernate.cfg.NamingStrategy)

setSchemaUpdate

public void setSchemaUpdate(boolean schemaUpdate)

Set whether to execute a schema update after SessionFactory initialization.

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

See Also:: Configuration.generateSchemaUpdateScript(net.sf.hibernate.dialect.Dialect, net.sf.hibernate.tool.hbm2ddl.DatabaseMetadata), SchemaUpdate

Fetch the LocalSessionFactoryBean itself rather than the exposed SessionFactory to be able to invoke this method, e.g. via LocalSessionFactoryBean lsfb = (LocalSessionFactoryBean) ctx.getBean("&mySessionFactory");.

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

Throws:: DataAccessException - in case of script execution errors
See Also:: Configuration.generateDropSchemaScript(net.sf.hibernate.dialect.Dialect), SchemaExport.drop(boolean, boolean)

createDatabaseSchema

getConfiguration

public net.sf.hibernate.cfg.Configuration getConfiguration()

Return the Configuration object used to build the SessionFactory. Allows access to configuration metadata stored there (rarely needed).

getObject

public Object getObject()

Return the singleton SessionFactory.

Specified by:: getObject in interface FactoryBean

Returns:: an instance of the bean (should not be null; a null value will be considered as an indication of incomplete initialization)
See Also:: FactoryBeanNotInitializedException

getObjectType

public Class getObjectType()

Description copied from interface: FactoryBean

Return the type of object that this FactoryBean creates, or null if not known in advance. This allows to check for specific types of beans without instantiating objects, for example on autowiring.

For a singleton, this should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.

This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.

NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

Specified by:: getObjectType in interface FactoryBean

Returns:: the type of object that this FactoryBean creates, or null if not known at the time of the call
See Also:: ListableBeanFactory.getBeansOfType(java.lang.Class)

isSingleton

public boolean isSingleton()

Description copied from interface: FactoryBean

Is the bean managed by this factory a singleton or a prototype? That is, will getObject() always return the same object (a reference that can be cached)?

NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from getObject() might get cached by the owning BeanFactory. Hence, do not return true unless the FactoryBean always exposes the same reference.

The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.

Specified by:: isSingleton in interface FactoryBean

Returns:: if this bean is a singleton
See Also:: FactoryBean.getObject()

destroy

public void destroy()
             throws net.sf.hibernate.HibernateException

Close the SessionFactory on bean factory shutdown.

Specified by:: destroy in interface DisposableBean

Throws:: net.sf.hibernate.HibernateException
