Examples with SessionFactoryImpl org.hibernate.internal.SessionFactoryImpl used on opensource projects

Example 1 with SessionFactoryImpl

use of org.hibernate.internal.SessionFactoryImpl in project hibernate-orm by hibernate.

the class EntityManagerFactoryUnwrapTest method testEntityManagerCanBeUnwrappedToSessionFactoryImpl.

@Test
public void testEntityManagerCanBeUnwrappedToSessionFactoryImpl() {
    SessionFactoryImpl sessionFactory = entityManagerFactory.unwrap(SessionFactoryImpl.class);
    assertNotNull("Unwrapping to SessionFactoryImpl should be ok", sessionFactory);
}

Example 2 with SessionFactoryImpl

use of org.hibernate.internal.SessionFactoryImpl in project midpoint by Evolveum.

the class OrgClosureManager method autoUpdateClosureTableStructure.

// TEMPORARY and quite BRUTAL HACK
// Originally in midPoint 3.0, m_org_closure has 5 columns, a non-null ID among them.
// In 3.1, it has 3, and no ID. Unfortunately, hibernate's hbm2ddl tool does not automatically remove ID column,
// so people can expect quite hard-to-understand error messages when running midPoint after upgrade.
//
// This code removes and re-creates the m_org_closure table if hbm2ddl is set to "update".
//
// returns true if the table was re-created
