有些情況接口需要返回的是xml數據，在springboot中並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 [email protected] * @date 2018/4/8 */@XmlRootElementpublic 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; }}
最後是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 [email protected] * @date 2018/4/8 */@RestControllerpublic 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; }}
到這裡就可以啟動項目了，訪問http://localhost:8080/json,可以看到如下圖
訪問http://localhost:8080/xml，如下圖
