@Deprecated public class HibernateJpaSessionFactoryBean extends EntityManagerFactoryAccessor implements FactoryBean<SessionFactory>
Deprecated.as of Spring Framework 4.3.12 against Hibernate 5.2, in favor of a custom solution based onEntityManagerFactory#unwrap
with explicit qualifiers and/or primary markersSimpleFactoryBean
that exposes the underlyingSessionFactory
behind a Hibernate-backed JPAEntityManagerFactory
.Primarily available for resolving a SessionFactory by JPA persistence unit name via the
"persistenceUnitName"
bean property.Note that, for straightforward cases, you could also simply declare a factory method:
<bean id="sessionFactory" factory-bean="entityManagerFactory" factory-method="getSessionFactory"/>
And as of JPA 2.1,
EntityManagerFactory#unwrap
provides a nice approach as well, in particular within configuration class arrangements:@Bean public SessionFactory sessionFactory(@Qualifier("entityManagerFactory") EntityManagerFactory emf) { return emf.unwrap(SessionFactory.class); }
Please note: Since Hibernate 5.2 changed itsSessionFactory
interface to extend JPA'sEntityManagerFactory
, you may get conflicts when injecting by type, with both the original factory and your customSessionFactory
matchingEntityManagerFactory
. An explicit qualifier for the original factory (as indicated above) is recommended here.- Since:

Method Detail
getObject
public SessionFactory getObject()
Deprecated.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 interfaceFactoryBean<SessionFactory>
- Returns:
- an instance of the bean (can be
null
) - See Also:
FactoryBeanNotInitializedException
getObjectType
public Class<?> getObjectType()
Deprecated.Description copied from interface:FactoryBean
Return the type of object that this FactoryBean creates, ornull
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 interfaceFactoryBean<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()
Deprecated.Description copied from interface:FactoryBean
Is the object managed by this factory a singleton? That is, willFactoryBean.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 returntrue
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 extendedSmartFactoryBean
interface may explicitly indicate independent instances through itsSmartFactoryBean.isPrototype()
method. PlainFactoryBean
implementations which do not implement this extended interface are simply assumed to always return independent instances if theisSingleton()
implementation returnsfalse
.- Specified by:
isSingleton
in interfaceFactoryBean<SessionFactory>
- Returns:
- whether the exposed object is a singleton
