SpringBoot返回json和xml的示例代码

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：

  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;


@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;

@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
