1、使用session的delete方法

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

 

2、使用HQL进行删除

 1     public void deleteUserHQL(User user){
 2         Session session = null;
 3         Transaction transaction = null;
 4         try {
 5             session = HibernateUtils.getSession();
 6             transaction = session.beginTransaction();
 7 
 8             String hql = " DELETE FROM User WHERE id = :id ";
 9             Query query = session.createQuery(hql);
10             query.setInteger("id",user.getId());
11 
12             query.executeUpdate();
13             transaction.commit();
14         }finally {
15             if (session != null){
16                 session.cancelQuery();
17             }
18         }
19     }
