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();
            }
        }
    }
