springboot返回json和xml

依赖！！！

<dependency>
            <groupId>com.fasterxml.jackson.dataformat</groupId>
            <artifactId>jackson-dataformat-xml</artifactId>
</dependency>

1、在pojo层添加User类

//被@XMLRootElement注解的类User,被描述为一个顶层的XML element */ 

@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;
    } 
/** * 该注解可以将被注解的（非静态）字段，或者被注解的get/set方法对应的字段映射为本地元素，也就是子元素。
     */ 
@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;
    }
}

2、controller层

@RestController
public class UserController {

    //http://localhost:8080/json
    @GetMapping(value = "/json",produces = MediaType.APPLICATION_JSON_VALUE)
    public User index(){
        User user = new User("echola", "22", "深圳");
        return user;
    }


    //http://localhost:8080/xml
    @GetMapping(value = "/xml",produces = MediaType.APPLICATION_XML_VALUE)
    public User XML(){
        User user = new User("echola", "22", "深圳");
        return user;
    }
}

启动项目成功后，输入http://localhost:8080/json，页面上的json字符串：

输入http://localhost:8080/xml，页面上Xml格式：
