1接受xml格式的数据

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>测试接收XML格式的数据</title>
    <script type="text/javascript" src="../js/json2.js"></script>
    <script src="http://libs.baidu.com/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function(){
            sendxml();
        });

        function sendxml(){
            var xmlData = "<?xml version="1.0" encoding="UTF-8" standalone="yes"?><computer><name>惠普</name><type>12</type></computer>";
            $.ajax("${pageContext.request.contextPath}/sendxml",// 发送请求的URL字符串。
                {
                    type : "POST",//  请求方式 POST或GET
                    contentType:"application/xml",//  发送信息至服务器时的内容编码类型
                    // 发送到服务器的数据。
                    data: xmlData,async:  true,// 默认设置下，所有请求均为异步请求。如果设置为false，则发送同步请求
                });
        }
    </script>
</head>
<body>

</body>
</html>

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Unmarshaller;

@Controller

2返回xml格式的数据

        $(document).ready(function(){
            readxml();
        });
        function readxml(){
            $.ajax("${pageContext.request.contextPath}/readxml",// 发送请求的URL字符串。
                {
                    dataType : "text",// 预期服务器返回的数据类型。
                    type : "POST",//  请求方式 POST或GET
                    async:  true,// 默认设置下，所有请求均为异步请求。如果设置为false，则发送同步请求
                    // 请求成功后的回调函数。
                    success :function(xml){
                        // 获得xml数据的id，name，author
                        var name = $("name",xml).text();
                        var type = $("type",xml).text();
                        var tr  = $("<tr align='center'/>");
