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">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.dalaoyang</groupId>
  <artifactId>springboot_xml</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>springboot_xml</name>
  <description>springboot_xml</description>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
  </parent>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
  </properties>

  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-devtools</artifactId>
      <scope>runtime</scope>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
    </dependency>

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

  <build>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
      </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
