SpringBoot返回json和xml

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：

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    4.0.0

    com.dalaoyang
    springboot_xml
    0.0.1-SNAPSHOT
    jar

    springboot_xml
    springboot_xml

    
        org.springframework.boot
        spring-boot-starter-parent
        1.5.9.RELEASE
         
    

    
        UTF-8
        UTF-8
        1.8
    

    
        
            org.springframework.boot
            spring-boot-starter-web
        

        
            org.springframework.boot
            spring-boot-devtools
            runtime
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        

        
            com.fasterxml.jackson.dataformat
            jackson-dataformat-xml
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

 

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 [email protected]
 * @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 [email protected]
 * @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
