第一步 首先要下载pager-taglib.jar

第二步  将<%@ taglib prefix="pg" uri="/WEB-INF/lib/pager-taglib.jar"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>添加到jsp头部 


PagerModel.java的类存放对象list和总数：

public class PagerModel<T> {

     private int total;

     private List<T> datas;

     public List<T> getDatas() {

         if ( datas == null )
         {
             datas = new ArrayList<T>();
         }
         return datas;
     }

     public void setDatas(List<T> datas) {

         this.datas = datas;
     }

     public int getTotal() {

         return total;
     }

     public void setTotal(int total) {

         this.total = total;
     }
 }


Pager.java是分页类

public class Pager implements java.io.Serializable {

     /**
      * @author Administrator
      * 
      */

     /**
      * 
      */
     private static final long serialVersionUID = -1060125092198748183L;

     private String offset;

     private String pageSize;

     public String getOffset() {

         return offset;
     }

     public void setOffset(String offset) {

         this.offset = offset;
     }

     public String getPageSize() {

         return pageSize;
     }

     public void setPageSize(String pageSize) {

         this.pageSize = pageSize;
     }

     public int getFirstindex() {

         offset = offset == null ? "0" : offset;
         return Integer.parseInt(offset);
     }

     public int getMaxresult() {

         pageSize = pageSize == null ? "10" : pageSize;
         return Integer.parseInt(pageSize);
     }

 }



这是test.jsp页面这里面的pm就是PagerModel的对象，Pager  pager是页面分页的规则都是从action传到页面的对象

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
 <%
 String path = request.getContextPath();
 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

 %>

 <%@ taglib prefix="pg" uri="/WEB-INF/lib/pager-taglib.jar"%>
 <%@taglib prefix="s" uri="/struts-tags" %>
 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
