    session.getTransaction().commit();
    session.close();
}

Example 53 with Session

    Customer customer = new Customer(1, "Samuel");
    session.saveOrUpdate(customer);
    session.getTransaction().commit();
    session.close();
}

Example 54 with Session

    Session session = openSession();
    session.createSQLQuery("select * from Customer").list();
    session.close();
    assertTrue(sessionFactory().getCache().containsEntity(Customer.class, 1));
}
