Hibernate常用方法之_修改

1、使用session的saveOrUpdate方法

 1     public void updateUser(User user){
 2         Session session = null;
 3         Transaction transaction = null;
 4         try {
 5             session = HibernateUtils.getSession();
 6             transaction = session.beginTransaction();
 7 
 8             session.saveOrUpdate(user);
 9 
10             transaction.commit();
11         }finally {
12             if (session != null){
13                 session.close();
14             }
15         }
16     }
