pager-taglib 使用说明
1、拷贝pager-taglib.jar包
2、在JSP页面中使用taglib指令引入pager-taglib标签库 <%@ taglib prefix="pg" uri="http://jsptags.com/tags/navigation/pager"%>
3、使用pager-taglib标签库进行分页处理
传两个值进去：1、pm.totles总记录数 2、pagesize 每页显示页数 3、<pg:param name="parentId"/>传给后台的变量值对（查询条件）
<pg:pager items="${total }" url="content/list.do" maxPageItems="${cont.length}" maxIndexPages="6" export="currentPageNumber=pageNumber" scope="request">
<pg:param name="categorys" value="${cont.categorys }" />
<pg:param name="labels" value="${cont.labels }" />
<jsp:include page="../../../res/jsp/pager_tag.jsp" flush="true" />
</pg:pager>
