java.lang.Objectorg.springframework.orm.hibernate.support.HibernateDaoSupport
Convenient super class for Hibernate data access objects.
Requires a SessionFactory to be set, providing a HibernateTemplate based on it to subclasses. Can alternatively be initialized directly via a HibernateTemplate, to reuse the latter's settings like SessionFactory, flush mode, exception translator, etc.
This base class is mainly intended for HibernateTemplate usage but can also be used when working with SessionFactoryUtils directly, e.g. in combination with HibernateInterceptor-managed Sessions. Convenience getSession and closeSessionIfNecessary methods are provided for that usage.

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware). |
protected void |
closeSessionIfNecessary(net.sf.hibernate.Session session)
Close the given Hibernate Session if necessary, created via this bean's SessionFactory, if it isn't bound to the thread. |

convertHibernateAccessException(net.sf.hibernate.HibernateException ex)
Convert the given HibernateException to an appropriate exception from the org.springframework.dao hierarchy. |
protected HibernateTemplate |
getHibernateTemplate()
Return the HibernateTemplate for this DAO, pre-initialized with the SessionFactory or set explicitly. |
protected net.sf.hibernate.Session |
getSession()
Get a Hibernate Session, either from the current transaction or a new one. |
protected net.sf.hibernate.Session |
getSession(boolean allowCreate)
Get a Hibernate Session, either from the current transaction or a new one. |
protected net.sf.hibernate.SessionFactory |
getSessionFactory()
Return the Hibernate SessionFactory used by this DAO. |
protected void |
initDao()
Subclasses can override this for custom initialization behavior. |
void |
setHibernateTemplate(HibernateTemplate hibernateTemplate)
Set the HibernateTemplate for this DAO explicitly, as an alternative to specifying a SessionFactory. |
void |
setSessionFactory(net.sf.hibernate.SessionFactory sessionFactory)
Set the Hibernate SessionFactory to be used by this DAO. |

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.
