Hibernate常用方法之_修改

1、使用session的saveOrUpdate方法

     public void updateUser(User user){
         Session session = null;
         Transaction transaction = null;
         try {
             session = HibernateUtils.getSession();
             transaction = session.beginTransaction();

             session.saveOrUpdate(user);

             transaction.commit();
         }finally {
             if (session != null){
                 session.close();
             }
         }
     }
