org.springframework.orm.hibernate3.support .HibernateDaoSupport

HibernateDaoSupport

abstract public class HibernateDaoSupport extends DaoSupport (Code)

Convenient super class for Hibernate-based data access objects.

Requires a org.hibernate.SessionFactory to be set, providing a org.springframework.orm.hibernate3.HibernateTemplate based on it to subclasses through the HibernateDaoSupport.getHibernateTemplate() 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 base class is mainly intended for HibernateTemplate usage but can also be used when working with a Hibernate Session directly, for example when relying on transactional Sessions. Convenience HibernateDaoSupport.getSession and HibernateDaoSupport.releaseSession methods are provided for that usage style.

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 HibernateDaoSupport.createHibernateTemplate .

Method Detail

checkDaoConfig
final protected void checkDaoConfig()(Code)

convertHibernateAccessException

final protected DataAccessException convertHibernateAccessException(HibernateException ex)(Code)

Convert the given HibernateException to an appropriate exception from the org.springframework.dao hierarchy. Will automatically detect wrapped SQLExceptions and convert them accordingly.

Delegates to the org.springframework.orm.hibernate3.HibernateTemplate.convertHibernateAccessException method of this DAO's HibernateTemplate.

Typically used in plain Hibernate code, in combination with HibernateDaoSupport.getSession and HibernateDaoSupport.releaseSession .
Parameters:
ex - HibernateException that occured the corresponding DataAccessException instance
See Also: org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException

createHibernateTemplate
protected HibernateTemplate createHibernateTemplate(SessionFactory sessionFactory)(Code)
	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. Parameters: sessionFactory - the Hibernate SessionFactory to create a HibernateTemplate for the new HibernateTemplate instance See Also: HibernateDaoSupport.setSessionFactory

getHibernateTemplate
final public HibernateTemplate getHibernateTemplate()(Code)
	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 HibernateDaoSupport.initDao implementation). Consider creating a custom HibernateTemplate instance via `new HibernateTemplate(getSessionFactory())`, in which case you're allowed to customize the settings on the resulting instance.

getSession

final protected Session getSession() throws DataAccessResourceFailureException, IllegalStateException(Code)

Obtain a Hibernate Session, either from the current transaction or a new one. The latter is only allowed if the org.springframework.orm.hibernate3.HibernateTemplate.setAllowCreate "allowCreate" setting of this bean's HibernateDaoSupport.setHibernateTemplate HibernateTemplate is "true".

Note that this is not meant to be invoked from HibernateTemplate code but rather just in plain Hibernate code. Either rely on a thread-bound Session or use it in combination with HibernateDaoSupport.releaseSession .

In general, it is recommended to use HibernateTemplate, either with the provided convenience operations or with a custom HibernateCallback that provides you with a Session to work on. HibernateTemplate will care for all resource management and for proper exception conversion. the Hibernate Session
throws:
  DataAccessResourceFailureException - if the Session couldn't be created
throws:
  IllegalStateException - if no thread-bound Session found and allowCreate=false
See Also:   org.springframework.orm.hibernate3.SessionFactoryUtils.getSession(SessionFactoryboolean)

getSession

final protected Session getSession(boolean allowCreate) throws DataAccessResourceFailureException, IllegalStateException(Code)

Obtain a Hibernate Session, either from the current transaction or a new one. The latter is only allowed if "allowCreate" is true.

In general, it is recommended to use HibernateDaoSupport.getHibernateTemplate() HibernateTemplate , either with the provided convenience operations or with a custom org.springframework.orm.hibernate3.HibernateCallback that provides you with a Session to work on. HibernateTemplate will care for all resource management and for proper exception conversion.
Parameters:
  allowCreate - if a non-transactional Session should be created when notransactional Session can be found for the current thread the Hibernate Session
throws:
  DataAccessResourceFailureException - if the Session couldn't be created
throws:
  IllegalStateException - if no thread-bound Session found and allowCreate=false
See Also:   org.springframework.orm.hibernate3.SessionFactoryUtils.getSession(SessionFactoryboolean)

getSessionFactory
final public SessionFactory getSessionFactory()(Code)
	Return the Hibernate SessionFactory used by this DAO.

releaseSession
final protected void releaseSession(Session session)(Code)
	Close the given Hibernate Session, created via this DAO's SessionFactory, if it isn't bound to the thread (i.e. isn't a transactional Session). Typically used in plain Hibernate code, in combination with HibernateDaoSupport.getSession and HibernateDaoSupport.convertHibernateAccessException . Parameters: session - the Session to close See Also: org.springframework.orm.hibernate3.SessionFactoryUtils.releaseSession

setHibernateTemplate
final public void setHibernateTemplate(HibernateTemplate hibernateTemplate)(Code)
	Set the HibernateTemplate for this DAO explicitly, as an alternative to specifying a SessionFactory. See Also: HibernateDaoSupport.setSessionFactory

setSessionFactory
final public void setSessionFactory(SessionFactory sessionFactory)(Code)
	Set the Hibernate SessionFactory to be used by this DAO. Will automatically create a HibernateTemplate for the given SessionFactory. See Also: HibernateDaoSupport.createHibernateTemplate See Also: HibernateDaoSupport.setHibernateTemplate
