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：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<build>

</plugin>
</plugins>
</build>
</project>
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
*/
@XmlRootElement
public 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
*/
@RestController
public 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
