@Repository
@Transactional
public class ReplyDao extends BaseDao {
/**
     * 分页查询用户
     */
    public List<User> listUsers(int pageNo, int pageCount) {
        String hql = "from User";
        Query query = getSession().createQuery(hql);
        if (pageNo > 0 && pageCount > 0) {
            query.setFirstResult((pageNo - 1) * pageCount);
            query.setMaxResults(pageCount);
        }
        return query.list();
    }
}
