Method Detail

getSession

protected abstract org.hibernate.Session getSession()

protected Session getSession() {
return session
}


eg in any container
@PersistenceContext private EntityManager entityManager;

protected Session getSession() {
return (Session) entityManager.getdelegate();
}

Ensure to clean the resources after use. If the session has been directly or indirectly injected, this method is empty
