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：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 <?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：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 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：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 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

访问http://localhost:8080/xml，如下图
