pager-taglib使用示范
  1. 把pager-taglib.jar导入到当前项目/Test/WebRoot/WEB-INF/lib下
  2. 建立一个分页类 
    package web;

import java.util.List;

/**
    
 * 分页模型
    
 *
    
 */
    
public class PagerModel {

	// 总记录数
    
	private int total;
    
	// 当前页的结果集
    
	private List datas;

	public int getTotal() {
    
		return total;
    
	}

	public void setTotal(int total) {
    
		this.total = total;
    
	}

	public List getDatas() {
    
		return datas;
    
	}

	public void setDatas(List datas) {
    
		this.datas = datas;
    
	}

}
  3. 建立一个JSP页面 
    <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
    
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
    
<%@ taglib uri="http://jsptags.com/tags/navigation/pager" prefix="pg"%>
    
<html>
    
<head>
    
<base href="<%=basePath%>">
    
<title>新闻列表</title>
    
</head>
    
<body>
    
<pg:pager items="22" url="news.do" index="half-full" maxPageItems="5"
    
		maxIndexPages="10" isOffset="<%=false%>"
    
		export="pageOffset,currentPageNumber=pageNumber" scope="request">
    
  <pg:param name="method" value="all" />
    
  <table align="center">
    
    <c:forEach items="${newsList}" var="nlist">
    
      <tr>
    
        <td>${nlist.sort.stname}</td>
    
        <td><a href="news.do?method=info&nid=${nlist.nid}"
    
						target="_blank">${nlist.ntitle}</a></td>
    
        <td><fmt:formatDate value="${nlist.ntime}"
    
							pattern="yyyy/MM/dd HH:mm" /></td>
    
      </tr>
    
    </c:forEach>
    
  </table>
    
  <pg:index export="total=itemCount">
    
    <center>
    
      <table border=1 cellpadding=0 width=70% cellspacing=0>
    
        <tr align=center valign=top>
    
          <pg:first>
    
            <td width="50">总计${total}个记录，第${currentPageNumber} /
    
              <fmt:formatNumber pattern="0" value="${total % 5 == 0 ? total / 5 :total / 5 +1}" />
    
              页</td>
    
            <c:choose>
    
              <c:when test="${currentPageNumber ne pageNumber}">
    
                <td width="50"><a href="<%=pageUrl%>&pageNo=<%=pageNumber%>"><b>首页</b> </a></td>
    
              </c:when>
    
              <c:otherwise>
    
                <td width="50"><b>首页</b></td>
    
              </c:otherwise>
    
            </c:choose>
    
          </pg:first>
    
          <pg:prev ifnull="true">
    
            <c:choose>
