SpringBoot返回json和xml的示例代码

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 [email protected]   * @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 [email protected]   * @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
