有些情况接口需要返回的是xml数据，在springboot中并不需要每次都转换一下数据格式，只需做一些微调整即可。
新建一个springboot项目，加入依赖jackson-dataformat-xml，pom文件代码如下：

启动类默认即可，没有做任何调整。
新建一个user类，代码如下：

package com.dalaoyang.entity;import javax.xml.bind.annotation.xmlelement;import javax.xml.bind.annotation.xmlrootelement;/** * @author dalaoyang * @description * @project springboot_learn * @package com.dalaoyang.entity * @email yangyang@dalaoyang.cn * @date 2018/4/8 */@xmlrootelementpublic class user { string username; string userage; string useraddress; public user(string username, string userage, string useraddress) { this.username = username; this.userage = userage; this.useraddress = useraddress; } @xmlelement public string getusername() { return username; } public void setusername(string username) { this.username = username; } @xmlelement public string getuserage() { return userage; } public void setuserage(string userage) { this.userage = userage; } @xmlelement public string getuseraddress() { return useraddress; } public void setuseraddress(string useraddress) { this.useraddress = useraddress; }} |
最后是controller，代码如下：

package com.dalaoyang.controller;import com.dalaoyang.entity.user;import org.springframework.http.mediatype;import org.springframework.web.bind.annotation.getmapping;import org.springframework.web.bind.annotation.restcontroller;/** * @author dalaoyang * @description * @project springboot_learn * @package com.dalaoyang.controller * @email yangyang@dalaoyang.cn * @date 2018/4/8 */@restcontrollerpublic class usercontroller { //http://localhost:8080/json @getmapping(value = "/json",produces = mediatype.application_json_value) public user index(){ user user = new user("dalaoyang", "26", "北京"); return user; } //http://localhost:8080/xml @getmapping(value = "/xml",produces = mediatype.application_xml_value) public user xml(){ user user = new user("dalaoyang", "26", "北京"); return user; }} |
到这里就可以启动项目了，访问http://localhost:8080/json,可以看到如下图
访问http://localhost:8080/xml，如下图
