hibernate4中对象的四种状态

与其说Hibernate操作数据库,不如说Hibernate操作对象的状态.

1,瞬时状态(transient)

2,持久化状态(persistent)

3,游离状态(detached)

Session s = HibernateUtil.getInstance().getSession();s.beginTransaction();//临时(瞬间状态)transientUser user = new User();user.setName("张三");s.save(user);//持久化状态persistents.getTransaction().commit();s.close();//游离状态detached
