Servlet类写网站访问量 servlet+jsp

Servlet端写网站访问量:
package com.mison;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestCounter extends HttpServlet {
	public void init(javax.servlet.ServletConfig config)
			throws ServletException {
		System.out.println("访问器初始化开始。。。。。");
	};

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		ServletContext servletcontext = request.getSession()
				.getServletContext();

		if (null == servletcontext.getAttribute("Counter")) {
			servletcontext.setAttribute("Counter", 1);
		} else {
			int counter = (Integer) servletcontext.getAttribute("Counter");

			servletcontext.setAttribute("Counter", counter + 1);
		}
       RequestDispatcher pd=         request.getRequestDispatcher("TestCounter.jsp");
       
       pd.forward(request, response);
	}

}




JSP页面写显示访问量

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

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'TestCounter.jsp' starting page</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

  </head>
  
  <body>
      已有<%=application.getAttribute("Counter") %>访问过此页面
  </body>
</html>
