Hibernate常用方法之_删除

1、使用session的delete方法

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

             session.delete(user);

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

2、使用HQL进行删除

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

             String hql = " DELETE FROM User WHERE id = :id ";
             Query query = session.createQuery(hql);
             query.setInteger("id",user.getId());

             query.executeUpdate();
             transaction.commit();
         }finally {
             if (session != null){
                 session.cancelQuery();
             }
         }
     }
