hibernate 的分页查询

/* 使用HQL分页查询Customer信息 */
    public static List<Customer> listPageCustomer_HQL(int pageNo, int perPageNum) {
        Session session = HibernateUtils.getSession();
        String hql = "from Customer c order by c.userName desc";
        Query query = session.createQuery(hql);
        query.setFirstResult((pageNo - 1) * perPageNum);
        query.setMaxResults(perPageNum);
        List<Customer> list = query.list();
        return list;
    }
