<a href="${pageContext.request.contextPath }/servlet/PageCustServlet?thispage=${page.firstpage }">首页</a>
<a href="${pageContext.request.contextPath }/servlet/PageCustServlet?thispage=${page.prepage }">上一页</a>

<!-- 分页逻辑开始 -->
<c:if test="${page.countpage<=5}">
<c:set var="begin" value="1" scope="page"></c:set>
<c:set var="end" value="${page.countpage}" scope="page"></c:set>
