java.lang.Objectorg.springframework.orm.toplink.LocalSessionFactory
org.springframework.orm.toplink.LocalSessionFactoryBean
public class LocalSessionFactoryBean
FactoryBean that creates a
 TopLink SessionFactory. This is the usual way to set up a shared
 TopLink SessionFactory in a Spring application context; the SessionFactory
 can then be passed to TopLink-based DAOs via dependency injection.
 
See the base class LocalSessionFactory for configuration details.
 
This class also implements the
 PersistenceExceptionTranslator
 interface, as autodetected by Spring's
 PersistenceExceptionTranslationPostProcessor,
 for AOP-based translation of native exceptions to Spring DataAccessExceptions.
 Hence, the presence of a LocalSessionFactoryBean automatically enables a
 PersistenceExceptionTranslationPostProcessor to translate TopLink exceptions.
 
If your DAOs expect to receive a raw TopLink Session, consider defining a
 TransactionAwareSessionAdapter
 in front of this bean. This adapter will provide a TopLink Session rather
 than a SessionFactory as bean reference. Your DAOs can then, for example,
 access the currently active Session and UnitOfWork via
 Session.getActiveSession() and Session.getActiveUnitOfWork(),
 respectively. Note that you can still access the SessionFactory as well, by
 defining a bean reference that points directly at the LocalSessionFactoryBean.

public void setJdbcExceptionTranslator(SQLExceptionTranslator jdbcExceptionTranslator)
Applied to any SQLException root cause of a TopLink DatabaseException, within Spring's PersistenceExceptionTranslator mechanism. The default is to rely on TopLink's native exception translation.

 which case a default ClassLoader must be used, for example

                        throws oracle.toplink.exceptions.TopLinkException
InitializingBeanThis 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.
afterPropertiesSet in interface InitializingBeanoracle.toplink.exceptions.TopLinkExceptionpublic Object getObject()
FactoryBeanAs 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.
getObject in interface FactoryBeannull)FactoryBeanNotInitializedExceptionpublic Class getObjectType()
FactoryBeannull 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.
getObjectType in interface FactoryBeannull if not known at the time of the callListableBeanFactory.getBeansOfType(java.lang.Class)public boolean isSingleton()
FactoryBeanFactoryBean.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.

SmartFactoryBean.isPrototype()public DataAccessException translateExceptionIfPossible(RuntimeException ex)
Converts the exception if it is a TopLinkException;
 else returns null to indicate an unknown exception.
