有些情況接口需要返回的是xml數據，在springboot中并不需要每次都轉換一下數據格式，只需做一些微調整即可。

新建一個springboot項目，加入依賴jackson-dataformat-xml，pom文件代碼如下：

<?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>

啟動類默認即可，沒有做任何調整。

新建一個user類，代碼如下：

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;}@XmlElementpublic String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}@XmlElementpublic String getUserAge() {return userAge;}public void setUserAge(String userAge) {this.userAge = userAge;}@XmlElementpublic String getUserAddress() {return userAddress;}public void setUserAddress(String userAddress) {this.userAddress = userAddress;} }

最后是controller，代碼如下：

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;} }

到這里就可以啟動項目了，訪問http://localhost:8080/json,可以看到如下圖

訪問http://localhost:8080/xml，如下圖
