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
