public class LocalSessionFactoryBean extends AbstractSessionFactoryBean implements BeanClassLoaderAware
FactoryBean
that creates a
Hibernate SessionFactory
. This is the usual way to
set up a shared Hibernate SessionFactory in a Spring application context;
the SessionFactory can then be passed to Hibernate-based DAOs via
dependency injection.
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, with the latter only necessary for
transactions which span multiple databases.
This factory bean will by default expose a transaction-aware SessionFactory
proxy, letting data access code work with the plain Hibernate SessionFactory
and its getCurrentSession()
method, while still being able to
participate in current Spring-managed transactions: with any transaction
management strategy, either local or JTA / EJB CMT, and any transaction
synchronization mechanism, either Spring or JTA. Furthermore,
getCurrentSession()
will also seamlessly work with
a request-scoped Session managed by
OpenSessionInViewFilter
/
OpenSessionInViewInterceptor
.
Requires Hibernate 3.6 or later, as of Spring 4.0. Note that this factory will use "on_close" as default Hibernate connection release mode, unless in the case of a "jtaTransactionManager" specified, for the reason that this is appropriate for most Spring-based applications (in particular when using Spring's HibernateTransactionManager).

public static DataSource getConfigTimeDataSource()
This instance will be set before initialization of the corresponding SessionFactory, and reset immediately afterwards. It is thus only available during configuration.
public static TransactionManager getConfigTimeTransactionManager()
This instance will be set before initialization of the corresponding SessionFactory, and reset immediately afterwards. It is thus only available during configuration.
public static LobHandler getConfigTimeLobHandler()
This instance will be set before initialization of the corresponding SessionFactory, and reset immediately afterwards. It is thus only available during configuration.
public void setConfigurationClass(Class<?> configurationClass)
Default is Configuration
; any subclass
of this default Hibernate Configuration class can be specified.
public void setConfigLocation(Resource configLocation)
Note: Can be omitted when all necessary properties and mapping resources are specified locally via this bean.
Configuration.configure(java.net.URL)
public void setConfigLocations(Resource[] configLocations)
Note: Can be omitted when all necessary properties and mapping resources are specified locally via this bean.
Configuration.configure(java.net.URL)
public void setMappingResources(String[] mappingResources)
Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.
public void setMappingLocations(Resource[] mappingLocations)
Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.
public void setCacheableMappingLocations(Resource[] cacheableMappingLocations)
Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.
public void setMappingJarLocations(Resource[] mappingJarLocations)
Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.
Configuration.addJar(java.io.File)
public void setMappingDirectoryLocations(Resource[] mappingDirectoryLocations)

Configuration.addDirectory(java.io.File)
public void setHibernateProperties(Properties hibernateProperties)
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.
public Properties getHibernateProperties()
public void setJtaTransactionManager(TransactionManager jtaTransactionManager)
Note: If this is set, the Hibernate settings should not define a transaction manager lookup to avoid meaningless double configuration.
LocalTransactionManagerLookup
public void setCacheRegionFactory(RegionFactory cacheRegionFactory)
Note: If this is set, the Hibernate settings should not define a cache provider to avoid meaningless double configuration.
RegionFactory
public void setLobHandler(LobHandler lobHandler)
public void setEntityInterceptor(Interceptor entityInterceptor)
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.
public void setNamingStrategy(NamingStrategy namingStrategy)
public void setTypeDefinitions(TypeDefinitionBean[] typeDefinitions)
Unfortunately, Hibernate itself does not define a complete object that represents a type definition, hence the need for Spring's TypeDefinitionBean.
public void setFilterDefinitions(FilterDefinition[] filterDefinitions)
Typically, the passed-in FilterDefinition objects will have been defined as Spring FilterDefinitionFactoryBeans, probably as inner beans within the LocalSessionFactoryBean definition.
public void setEntityCacheStrategies(Properties entityCacheStrategies)
For example:
<property name="entityCacheStrategies"> <props> <prop key="com.mycompany.Customer">read-write</prop> <prop key="com.mycompany.Product">read-only,myRegion</prop> </props> </property>
entityCacheStrategies
- properties that define entity cache strategies,
with class names as keys and cache concurrency strategies as valuesConfiguration.setCacheConcurrencyStrategy(String, String)
public void setCollectionCacheStrategies(Properties collectionCacheStrategies)
For example:

listener objects as valuespublic void setSchemaUpdate(boolean schemaUpdate)
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 org.hibernate.cfg.Configuration as Hibernate's own SchemaUpdate tool.
