我们再编写一个测试用的Servlet：

[java]
public class PagerServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {

        int curPage = Integer.parseInt(req.getParameter("page") == null ? "1"
                : req.getParameter("page"));
        List list = new ArrayList();

        int start = (curPage -1)* 10 + 1;
        int end = start + 10 > 26 ? 26 : start + 10;
        for(int i = start; i < end; i++){
            list.add(i);
        }

        PageBean pageBean = new PageBean(25, curPage, list);
        req.setAttribute("pb", pageBean);


        RequestDispatcher rd = req.getRequestDispatcher("index.jsp");
        rd.forward(req,resp);
    }
}
这样我们就可以在我们的JSP页面中使用我们自己的标签来完成分页条的显示了。

[html]
<%@ page language="java" import="java.util.*,com.luojing.pager.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="luo" uri="/luo_pager" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <title>pager test</title>
</head>

<body>
    <%
        PageBean p = (PageBean) request.getAttribute("pb");
        List<Integer> list = p.getItems();
        for(Integer i : list){
            pageContext.getOut().write("值为: " + i + "<br/>");
        }
