如题，ajax访问不到servlet，可以访问到js
jsp代码：

<%@ page language="java" 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 JSF 'ajaxDemo.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">

    -->

    <script type="text/javascript" src="jquery-3.0.0.js"></script>

    <script type="text/javascript" src="ajaxFun.js"></script>

</head>



<body>

    <form id="form">

        UserName:<input type="text" name="username" id="username">

        PassWord:<input type="password" name="password" id="password">

        <button type="button" onclick="ajaxFun()">AJAX功能</button>

    </form>

</body>

</html>

js代码：

function ajaxFun(){

    $.ajax({

        type: "POST",

        url: "TestServlet1",

        data: $('#form').serialize(),

        success: function(msg){

                $.messager.alert('信息','模板保存成功');

        }

    })

}

servlet代码：

package action;



import java.io.IOException;

import java.io.PrintWriter;



import javax.jws.soap.SOAPBinding.Use;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



import bean.User;

import com.google.gson.Gson;





	public class TestServlet1 extends HttpServlet {



	    public TestServlet1() {

	        super();

	    }



	    public void doGet(HttpServletRequest request, HttpServletResponse response)

	            throws ServletException, IOException {



	        doPost(request, response);

	    }



	    public void doPost(HttpServletRequest request, HttpServletResponse response)

	            throws ServletException, IOException {



	        response.setContentType("text/html");

	        PrintWriter out = response.getWriter();

	        System.out.println("进来啦");

	        String username=request.getParameter("username");

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



	        System.out.println("UserName:"+username+";"+"PassWord:"+password);



	        Gson gson=new Gson();

	        User user=new User();

	        user.setUsername(username);

	        user.setPassword(password);



	        String info=gson.toJson(user);

	        System.out.println(info);



	        out.print("success");

	        out.flush();

	        out.close();

	    }



	}
