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.
NOTE: This variant of LocalSessionFactoryBean requires Hibernate 4.0 or higher.
It is similar in role to the same-named class in the orm.hibernate3
package.
However, in practice, it is closer to AnnotationSessionFactoryBean
since
its core purpose is to bootstrap a SessionFactory
from annotation scanning.
NOTE: To set up Hibernate 4 for Spring-driven JTA transactions, make
sure to either specify the "jtaTransactionManager"
bean property or to set the "hibernate.transaction.factory_class" property to
CMTTransactionFactory
.
Otherwise, Hibernate's smart flushing mechanism won't work properly.

classpath.
|
void |
setResourceLoader(ResourceLoader resourceLoader)
Set the ResourceLoader that this object runs in.

public void setDataSource(DataSource dataSource)
If this is set, the Hibernate settings should not define a connection provider to avoid meaningless double configuration.
public void setConfigLocation(Resource configLocation)
Note: Can be omitted when all necessary properties and mapping resources are specified locally via this bean.
public void setConfigLocations(Resource[] configLocations)
Note: Can be omitted when all necessary properties and mapping resources are specified locally via this bean.
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)
Can be used to add to mappings from a Hibernate XML config file, or to specify all mappings locally.

public void setHibernateProperties(Properties hibernateProperties)
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.

ResourceLoaderAware
This might be a ResourcePatternResolver, which can be checked
through instanceof ResourcePatternResolver
. See also the
ResourcePatternUtils.getResourcePatternResolver
method.
Invoked after population of normal bean properties but before an init callback
like InitializingBean's afterPropertiesSet
or a custom init-method.
Invoked before ApplicationContextAware's setApplicationContext
.

InitializingBean
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.

protected SessionFactory buildSessionFactory(LocalSessionFactoryBuilder sfb)
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.

FactoryBean
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.

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.

public boolean isSingleton()
FactoryBean
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
.
