**测试发送xml数据**

创建User

package com.po;
    import javax.xml.bind.annotation.XmlRootElement;
    @XmlRootElement
    public class User {
    	private String userName;
    	private String passWord;
    	public String getUserName() {
    		return userName;
    	}
    	public void setUserName(String userName) {
    		this.userName = userName;
    	}
    	public String getPassWord() {
    		return passWord;
    	}
    	public void setPassWord(String passWord) {
    		this.passWord = passWord;
    	}
    	@Override
    	public String toString() {
    		return "User [userName=" + userName + ", passWord=" + passWord + "]";
    	}
    }

创建UserController

package com.controller;
    import java.io.InputStream;
    import javax.xml.bind.JAXBContext;
    import javax.xml.bind.JAXBException;
    import javax.xml.bind.Unmarshaller;
    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 com.po.User;
    @Controller
    public class UserController {
    	@RequestMapping(value="/sendxml",method=RequestMethod.POST)
    	public void sendxml(@RequestBody User user) {
    		System.out.println(user);
    		System.out.println("接收xml数据成功");
    	}
    	@RequestMapping(value="/readxml",method=RequestMethod.POST)
    	@ResponseBody
    	public User readXml() throws JAXBException {
    		JAXBContext context = JAXBContext.newInstance(User.class);  
    		 Unmarshaller unmar = context.createUnmarshaller();  
    		 InputStream is = this.getClass().getResourceAsStream("/User.xml");
    		 User user=(User) unmar.unmarshal(is);
    		 return user;
    	}
    }

创建sendxml.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>发送xml格式数据</title>
    <script type="text/javascript" src="js/jquery-1.11.0.min.js"></script>
    <script type="text/javascript">
    	$(document).ready(function(){
    		sendxml();
    	});
    	
    	function sendxml(){
    		var xmlData = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><user><userName>张三</userName><passWord>zkddd522</passWord></user>";
    		$.ajax("${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>

**测试返回xml数据到页面**

src下创建User.xml

<?xml version="1.0" encoding="UTF-8"?>
    <user>
    	<userName>baixue</userName>
    	<passWord>ekd52</passWord>
    </user>

创建readxml.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>接收xml格式的数据</title>
    <script type="text/javascript" src="js/jquery-1.11.0.min.js"></script>
    <script type="text/javascript">
    	$(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 userName = $("userName", xml).text();
    				 	var passWord = $("passWord", xml).text();
    				 	$("#userName").html(userName);	
    				 	$("#passWord").html(passWord);	
    			   },
    			   // 请求出错时调用的函数
    			   error:function(){
    				   alert("数据接收失败");
    			   }
    		});
    	}
    </script>
    </head>
    <body>
    	用户名：<span id="userName"></span><br>
    	密码：<span id="passWord"></span>
    </body>
    </html>
