InitializingBean
public abstract class HibernateDaoSupport extends DaoSupport
Convenient super class for Hibernate-based data access objects.Requires a
SessionFactory
to be set, providing aHibernateTemplate
based on it to subclasses through thegetHibernateTemplate()
method. Can alternatively be initialized directly with a HibernateTemplate, in order to reuse the latter's settings such as the SessionFactory, exception translator, flush mode, etc.This class will create its own HibernateTemplate instance if a SessionFactory is passed in. The "allowCreate" flag on that HibernateTemplate will be "true" by default. A custom HibernateTemplate instance can be used through overriding
createHibernateTemplate(org.hibernate.SessionFactory)
.NOTE: Hibernate access code can also be coded in plain Hibernate style. Hence, for newly started projects, consider adopting the standard Hibernate style of coding data access objects instead, based on
SessionFactory.getCurrentSession()
. This HibernateTemplate primarily exists as a migration helper for Hibernate 3 based data access code, to benefit from bug fixes in Hibernate 4.x.- 从以下版本开始:

方法详细资料
setSessionFactory
public final void setSessionFactory(SessionFactory sessionFactory)
Set the Hibernate SessionFactory to be used by this DAO. Will automatically create a HibernateTemplate for the given SessionFactory.
createHibernateTemplate
protected HibernateTemplate createHibernateTemplate(SessionFactory sessionFactory)
Create a HibernateTemplate for the given SessionFactory. Only invoked if populating the DAO with a SessionFactory reference!Can be overridden in subclasses to provide a HibernateTemplate instance with different configuration, or a custom HibernateTemplate subclass.
- 参数:
sessionFactory
- the Hibernate SessionFactory to create a HibernateTemplate for- 返回:
- the new HibernateTemplate instance
- 另请参阅:
setSessionFactory(org.hibernate.SessionFactory)
getSessionFactory
public final SessionFactory getSessionFactory()
Return the Hibernate SessionFactory used by this DAO.
setHibernateTemplate
public final void setHibernateTemplate(HibernateTemplate hibernateTemplate)
Set the HibernateTemplate for this DAO explicitly, as an alternative to specifying a SessionFactory.
getHibernateTemplate
public final HibernateTemplate getHibernateTemplate()
Return the HibernateTemplate for this DAO, pre-initialized with the SessionFactory or set explicitly.Note: The returned HibernateTemplate is a shared instance. You may introspect its configuration, but not modify the configuration (other than from within an
DaoSupport.initDao()
implementation). Consider creating a custom HibernateTemplate instance vianew HibernateTemplate(getSessionFactory())
, in which case you're allowed to customize the settings on the resulting instance.
checkDaoConfig
protected final void checkDaoConfig()
从类复制的说明:DaoSupport
Abstract subclasses must override this to check their configuration.Implementors should be marked as
final
if concrete subclasses are not supposed to override this template method themselves.- 指定者:
checkDaoConfig
在类中DaoSupport
currentSession
protected final Session currentSession() throws DataAccessResourceFailureException
Conveniently obtain the current Hibernate Session.- 返回:
- the Hibernate Session
- 抛出:
DataAccessResourceFailureException
- if the Session couldn't be created- 另请参阅:
SessionFactory.getCurrentSession()
