The three states of hibernate learning and their life cycle

Three different states:

Life cycle:

The code indicates:

//三种状态    publicvoidtestThreeState(){        TUser user=newTUser();        user.setName("spark");  //此时user处于Transient                try{            Transaction tx=session.beginTransaction();            session.save(user); //user对象已经由hibernate纳入管理器，处于persistent状态            tx.commit();            session.close();   //user对象此时为Detached状态，因为与其关联的session已经关闭                        Transaction tx2=session2.beginTransaction();            session2.update(user);//user对象借助session2，由hibernate纳入管理容器，恢复persistent状态   update并没有发送sql语句            user.setName("spark_1");//处于persistent状态，其属性变更将自动由hibernate固话到数据库中   ！！！！            tx2.commit();           //commit之前调用session.flush()在其中发送sql语句        } catch(HibernateException e) {            e.printStackTrace();        }    }
