jquery的Ajax框架乱码解决

1.下面代码为服务器端获取请求信息Servlet,真正用的时候可能就是struts等

package com.adu;

import java.io.IOException;
import java.io.PrintWriter;
import java.net.URLDecoder;

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

public class AjaxServer extends HttpServlet {

    private static final long serialVersionUID = -1391282338046351379L;

    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        response.setContentType("text/html");
        response.setCharacterEncoding("UTF-8");

        PrintWriter out = response.getWriter();
        商账追收
        //获取页面jquery的url提交的数据，进行处理
//        String userName = request.getParameter("name");
//        String passWord = request.getParameter("password");

        String name = request.getParameter("name");
         String password = request.getParameter("password");

        //转换字符集编码,避免中文乱码问题
        String userName = URLDecoder.decode(name,"UTF-8");
        String passWord = URLDecoder.decode(password,"UTF-8");


        //进行逻辑判断，看输入是否合法
        if(userName.length() != 0 && userName != null && passWord.length() != 0 && passWord != null){

            if(userName.equals("mawanli") && passWord.equals("123")){

                //out.print("Welcome* "+userName+" *visit my web!");
                out.print("欢迎* "+userName+" *访问！");
                out.flush();
                out.close();

            }else{

                out.print("sorry please login again!");
//                out.print("请输入正确的用户名和密码！");
            }
        }
        else{

            out.print("please input right name and password!");
            //out.print("请重新登录！");
        }

    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        resp.setContentType("text/html");
        this.doGet(req, resp);
    }

}

2.以下是页面测试的代码：

<%@ 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>测试ajax验证登录</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">
    

<script type="text/javascript" src="js/jquery-1.6.min.js"></script></head>
<script type="text/javascript">

//添加时间戳，以防每次测试为不同的url，解决浏览器缓存问题
function convertUrl(url) {

    var timestamp = (new Date()).valueOf();
      if (url.indexOf("?") >= 0) {
       url = url + "&t=" + timestamp;
      } else {   发型123
         url = url + "?t=" + timestamp;
     }
       return url;

}
//用encodeURI可以解决页面传值时的中文乱码问题
function validate(){
    var name = encodeURI(encodeURI($("#userName").val()));
      var password = encodeURI(encodeURI($("#passWord").val()));
      var url = "AjaxServer?name="+name+"&password="+password;
      url = convertUrl(url);

     $.get(url,null,function(data){
                               $("#result").html(data);
                       });
}

</script>

<body>
   <div align="center">
   <div >
   <form action="#" method="get">
   <table>
   <tr><td>用户名：</td><td><input type="text" name="userName" id="userName"/></td></tr>
   <tr><td>密    码：</td><td><input type="password" id="passWord"/></td></tr>
   <tr align="right"><td colspan="2"><input type="button" value="登录" onclick="validate()"/>
   <input type="reset" value="取消"/></td></tr>
   </table>
   </form>

   <div id="result"></div>
