@Test
public void insertTest(){
Session session = null;
Configuration config = new Configuration().configure();
SessionFactory sessionFactory = config.buildSessionFactory();
session = sessionFactory.openSession();
Transaction trans = null;
trans = session.beginTransaction();
CostType type = new CostType();
type.setName("Micheal");
session.save(type);
session.flush();
trans.commit();
Assert.assertEquals(type.getId() > 0, true);
session.close();
