All Implemented Interfaces:

Aware, DisposableBean, FactoryBean<SessionFactory>, InitializingBean, ResourceLoaderAware, PersistenceExceptionTranslator

public class LocalSessionFactoryBean
extends HibernateExceptionTranslator
implements FactoryBean<SessionFactory>, ResourceLoaderAware, InitializingBean, DisposableBean

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 data access objects via dependency injection.

Compatible with Hibernate 5.0/5.1 as well as 5.2, as of Spring 4.3.

Since:

4.2

Method Detail

setDataSource

public void setDataSource(javax.sql.DataSource dataSource)

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

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

setConfigLocation

public void setConfigLocation(Resource configLocation)

Set the location of a single 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)

setConfigLocations

public void setConfigLocations(Resource... configLocations)

Set the locations of multiple Hibernate XML config files, for example as classpath resources "classpath:hibernate.cfg.xml,classpath:extension.cfg.xml".

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

See Also:

setMappingResources

public void setMappingResources(java.lang.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)

setCacheableMappingLocations

public void setCacheableMappingLocations(Resource... cacheableMappingLocations)

Set locations of cacheable Hibernate mapping files, for example as web app resource "/WEB-INF/mapping/example.hbm.xml". Supports any resource location via Spring's resource abstraction, as long as the resource can be resolved in the file system.

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

See Also:

Configuration.addCacheableFile(File)

setMappingJarLocations

public void setMappingJarLocations(Resource... mappingJarLocations)

See Also:

Configuration.addDirectory(File)

setEntityInterceptor

public void setEntityInterceptor(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.

See Also:

Configuration.setInterceptor(org.hibernate.Interceptor)

setImplicitNamingStrategy

public void setImplicitNamingStrategy(org.hibernate.boot.model.naming.ImplicitNamingStrategy implicitNamingStrategy)

Set a Hibernate 5.0 ImplicitNamingStrategy for the SessionFactory.

setJtaTransactionManager

public void setJtaTransactionManager(java.lang.Object jtaTransactionManager)

Set the Spring JtaTransactionManager or the JTA TransactionManager to be used with Hibernate, if any. Implicitly sets up JtaPlatform.

See Also:

LocalSessionFactoryBuilder.setJtaTransactionManager(java.lang.Object)

setMultiTenantConnectionProvider

public void setMultiTenantConnectionProvider(org.hibernate.engine.jdbc.connections.spi.MultiTenantConnectionProvider multiTenantConnectionProvider)

Set a MultiTenantConnectionProvider to be passed on to the SessionFactory.

Since:

4.3

See Also:

LocalSessionFactoryBuilder.setMultiTenantConnectionProvider(org.hibernate.engine.jdbc.connections.spi.MultiTenantConnectionProvider)

setCurrentTenantIdentifierResolver

public void setCurrentTenantIdentifierResolver(CurrentTenantIdentifierResolver currentTenantIdentifierResolver)

Set a CurrentTenantIdentifierResolver to be passed on to the SessionFactory.

See Also:

LocalSessionFactoryBuilder.setCurrentTenantIdentifierResolver(org.hibernate.context.spi.CurrentTenantIdentifierResolver)

setEntityTypeFilters

public void setEntityTypeFilters(TypeFilter... entityTypeFilters)

Specify custom type filters for Spring-based scanning for entity classes.

Default is to search all specified packages for classes annotated with @javax.persistence.Entity, @javax.persistence.Embeddable or @javax.persistence.MappedSuperclass.

See Also:

setPackagesToScan(java.lang.String...)

setHibernateProperties

public void setHibernateProperties(java.util.Properties hibernateProperties)

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

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 java.util.Properties getHibernateProperties()

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

setAnnotatedClasses

public void setAnnotatedClasses(java.lang.Class<?>... annotatedClasses)

Specify annotated entity classes to register with this Hibernate SessionFactory.

See Also:

Configuration.addAnnotatedClass(Class)

setAnnotatedPackages

public void setAnnotatedPackages(java.lang.String... annotatedPackages)

Specify the names of annotated packages, for which package-level annotation metadata will be read.

See Also:

Configuration.addPackage(String)

setPackagesToScan

public void setPackagesToScan(java.lang.String... packagesToScan)

Specify packages to search for autodetection of your entity classes in the classpath. This is analogous to Spring's component-scan feature (ClassPathBeanDefinitionScanner).

setBootstrapExecutor

public void setBootstrapExecutor(AsyncTaskExecutor bootstrapExecutor)

Specify an asynchronous executor for background bootstrapping, e.g. a SimpleAsyncTaskExecutor.

SessionFactory initialization will then switch into background bootstrap mode, with a SessionFactory proxy immediately returned for injection purposes instead of waiting for Hibernate's bootstrapping to complete. However, note that the first actual call to a SessionFactory method will then block until Hibernate's bootstrapping completed, if not ready by then. For maximum benefit, make sure to avoid early SessionFactory calls in init methods of related beans, even for metadata introspection purposes.

Since:

4.3

See Also:

LocalSessionFactoryBuilder.buildSessionFactory(AsyncTaskExecutor)

setMetadataSources

public void setMetadataSources(org.hibernate.boot.MetadataSources metadataSources)

Specify a Hibernate MetadataSources service to use (e.g. reusing an existing one), potentially populated with a custom Hibernate bootstrap ServiceRegistry as well.

Since:

4.3

getMetadataSources

public org.hibernate.boot.MetadataSources getMetadataSources()

Determine the Hibernate MetadataSources to use.

Can also be externally called to initialize and pre-populate a MetadataSources instance which is then going to be used for SessionFactory building.

Returns:

the MetadataSources to use (never null)

Since:

4.3

See Also:

LocalSessionFactoryBuilder.LocalSessionFactoryBuilder(DataSource, ResourceLoader, MetadataSources)

setResourceLoader

public void setResourceLoader(ResourceLoader resourceLoader)

Specify a Spring ResourceLoader to use for Hibernate metadata.

Specified by:

setResourceLoader in interface ResourceLoaderAware

Parameters:

resourceLoader - the ResourceLoader to use (never null)

See Also:

ResourcePatternResolver, ResourcePatternUtils.getResourcePatternResolver(org.springframework.core.io.ResourceLoader)

getResourceLoader

public ResourceLoader getResourceLoader()

Determine the Spring ResourceLoader to use for Hibernate metadata.

Returns:

the ResourceLoader to use (never null)

Since:

4.3

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.io.IOException

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

java.io.IOException

buildSessionFactory

protected SessionFactory buildSessionFactory(LocalSessionFactoryBuilder sfb)

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 LocalSessionFactoryBean.

The default implementation invokes LocalSessionFactoryBuilder's buildSessionFactory. A custom implementation could prepare the instance in a specific way (e.g. applying a custom ServiceRegistry) or use a custom SessionFactoryImpl subclass.

Parameters:

sfb - LocalSessionFactoryBuilder prepared by this LocalSessionFactoryBean

Returns:

the SessionFactory instance

See Also:

LocalSessionFactoryBuilder.buildSessionFactory(org.springframework.core.task.AsyncTaskExecutor)

getConfiguration

public final Configuration getConfiguration()

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

Throws:

java.lang.IllegalStateException - if the Configuration object has not been initialized yet

getObject

@Nullable
public SessionFactory getObject()

Description copied from interface: FactoryBean

Return an instance (possibly shared or independent) of the object managed by this factory.

As with a BeanFactory, this allows support for both the Singleton and Prototype design pattern.

If this FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding FactoryBeanNotInitializedException.

As of Spring 2.0, FactoryBeans are allowed to return null objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate.

Specified by:

getObject in interface FactoryBean<SessionFactory>

Returns:

an instance of the bean (can be null)

See Also:

FactoryBeanNotInitializedException

getObjectType

public java.lang.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 one to check for specific types of beans without instantiating objects, for example on autowiring.

In the case of implementations that are creating a singleton object, this method 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<SessionFactory>

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<T>)

isSingleton

public boolean isSingleton()

Description copied from interface: FactoryBean

Is the object managed by this factory a singleton? That is, will FactoryBean.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.

NOTE: This method returning false does not necessarily indicate that returned objects are independent instances. An implementation of the extended SmartFactoryBean interface may explicitly indicate independent instances through its SmartFactoryBean.isPrototype() method. Plain FactoryBean implementations which do not implement this extended interface are simply assumed to always return independent instances if the isSingleton() implementation returns false.

The default implementation returns true, since a FactoryBean typically manages a singleton instance.

Specified by:

isSingleton in interface FactoryBean<SessionFactory>

Returns:

whether the exposed object is a singleton

See Also:

FactoryBean.getObject(), SmartFactoryBean.isPrototype()

destroy

public void destroy()

Description copied from interface: DisposableBean

Invoked by a BeanFactory on destruction of a singleton.

Specified by:

destroy in interface DisposableBean
