用到的工具类：

https://github.com/josdejong/httputil

要注意的问题：

1）引入javax.servlet.http.*文件出错，是因为没有add library，要加server runtime

2）spring mvc无法requestMapping根目录，是因为配置了welcome-file

步骤：

1. 继承了HttpUtil的工具类

public class HttpUtilXml extends HttpUtil {	/**	 * post an xml file	 */	static public String postXml(String url, String body,			Map
    
      headers) throws IOException {		// set content type		if (headers == null) {			headers = new HashMap
     
      ();		}		headers.put("Content-Type", "application/xml");		return post(url, body, headers);	}}

这样就可以接受xml的数据。

2. 要引入两个依赖


     
     
      com.fasterxml.jackson.core
      
     
      jackson-core
      
     
      2.8.1
     
    
     
     
      com.fasterxml.jackson.core
      
     
      jackson-databind
      
     
      2.8.1

3. 实体类中加入xml注解

package com.hengzecn.car.entity;import java.io.Serializable;import javax.xml.bind.annotation.XmlElement;import javax.xml.bind.annotation.XmlRootElement;@XmlRootElement(name= "User")public class User implements Serializable{    private static final long serialVersionUID = 1L;    private Integer id;    private String userName;    private String password;    public User(Integer id, String userName, String password) {        this.id = id;        this.userName = userName;        this.password = password;    }    public User(String userName, String password) {        this.userName = userName;        this.password = password;    }    public User() {    }    public Integer getId() {        return id;    }    public String getUserName() {        return userName;    }    public String getPassword() {        return password;    }    @XmlElement    public void setId(Integer id) {        this.id = id;    }    @XmlElement    public void setUserName(String userName) {        this.userName = userName;    }    @XmlElement    public void setPassword(String password) {        this.password = password;    }}

4. 接收xml文件

@RequestMapping(value = "/xml", method = RequestMethod.POST)    @ResponseBody    public User getXml(@RequestBody User user) {    	System.out.println(user.getPassword());    	return user;    }

5. 测试函数

@RequestMapping("/send_xml")    public void sendXml() throws IOException{    	String body = "
    
     
      1
     
     
      fan
     
     
      111
     
    ";    	String res = HttpUtilXml.postXml("http://129.0.5.11:8080/car/xml", body, null);    	//System.out.println(res);
