如何使用Spring Boot Rest Data返回xml

Question

我需要Spring引导休息数据的输出为xml而不是json。我已经放入了我的Repository对象：

@RequestMapping(value="/findByID", method=RequestMethod.GET, headers = { "Accept=application/xml" }, produces="application/xml")
MyXmlAnnotatedObject findById(@Param("id") BigInteger id);

我还将以下内容添加到我的pom dependancies

    <dependency>
        <groupId>com.fasterxml.jackson.dataformat</groupId>
        <artifactId>jackson-dataformat-xml</artifactId>
        <version>2.4.3</version>
    </dependency>

    <dependency>
        <groupId>org.codehaus.woodstox</groupId>
        <artifactId>woodstox-core-asl</artifactId>
        <version>4.4.1</version>
    </dependency>

但是当我尝试

时

http://localhost:9000/factset/search/findByID?id=18451

我仍然得到JSON。我真的需要为我的用户使用XML 任何想法？

Answer 1

RequestMapping注释不适用于存储库。存储库方法不允许您更改结果格式（默认为JSON）。如果您希望您的服务以XML格式返回数据，那么您需要创建简单的@Controller。

@Controller
public class RestEndpoint {

    @Autowired
    private SomeRepository someRepository;

    @RequestMapping(value="/findByID", method=RequestMethod.GET, produces=MediaType.APPLICATION_XML_VALUE)
    public @ResponseBody MyXmlAnnotatedObject findById(@Param("id") BigInteger id) {

        return someRepository.findById(id);
    }

}

UPD：以下是官方Spring文档的链接：http://docs.spring.io/spring-data/rest/docs/2.1.4.RELEASE/reference/html/repository-resources.html

**3.6 The query method resource**
The query method resource executes the query exposed through an individual query method on the repository interface.

**3.6.1 Supported HTTP methods**

As the search resource is a read-only resource it supports GET only.

**GET**

Returns the result of the query execution.

**Parameters**

If the query method has pagination capabilities (indicated in the URI template pointing to the resource) the resource takes the following parameters:

page - the page number to access (0 indexed, defaults to 0).
size - the page size requested (defaults to 20).
sort - a collection of sort directives in the format ($propertyname,)+[asc|desc]?.
**Supported media types**

application/hal+json
application/json

请不要因为恋尸癖而责怪我，但我已经创建了一个能够满足您需求的例子：https://github.com/sergpank/spring-boot-xml

简而言之，您应该告诉平台您在POST请求的标题中需要XML（如果您使用像Postman这样的工具进行测试）：

Accept : application/xml
Content-Type : application/xml

如果您要将XML消息转换器设置为RestTemplate：

，它将自动完成

public class RestfulClient {

    public static void main(String[] args) {
        RestTemplate restTemplate = new RestTemplate(Arrays.asList(new Jaxb2RootElementHttpMessageConverter()));

        Contact random = restTemplate.getForObject("http://localhost:8080/contact/random", Contact.class);
        System.out.println("Received: " + random);

        Contact edited = restTemplate.postForObject("http://localhost:8080/contact/edit", random, Contact.class);
        System.out.println("Edited: " + edited);
    }
}

不要忘记使用 @XmlRootElement 和 @XmlElement 注释（如果您更喜欢JAXB）注释您的课程：

@AllArgsConstructor
@NoArgsConstructor
@ToString
@Setter
@XmlRootElement
public class Contact implements Serializable {
    @XmlElement
    private Long id;

    @XmlElement
    private int version;

    @Getter private String firstName;

    @XmlElement
    private String lastName;

    @XmlElement
    private Date birthDate;

    public static Contact randomContact() {
        Random random = new Random();
        return new Contact(random.nextLong(), random.nextInt(), "name-" + random.nextLong(), "surname-" + random.nextLong(), new Date());
    }
}

您的控制器中的方法还应该有 @RequestBody 注释来解组XML和 @ResponseBody 注释来编组回复XML。

@Controller
@RequestMapping(value="/contact")
public class ContactController {
    final Logger logger = LoggerFactory.getLogger(ContactController.class);

    @RequestMapping("/random")
    @ResponseBody
    public Contact randomContact() {
        return Contact.randomContact();
    }

    @RequestMapping(value = "/edit", method = RequestMethod.POST)
    @ResponseBody
    public Contact editContact(@RequestBody Contact contact) {
        logger.info("Received contact: {}", contact);
        contact.setFirstName(contact.getFirstName() + "-EDITED");
        return contact;
    }
}

以下代码在我的Application for return XML content

中工作正常

代码：

            @SpringBootApplication
            @Configuration
            @ComponentScan
            @EnableAutoConfiguration
            @EnableScheduling
            public class Application extends SpringBootServletInitializer{



               public static void main(String[] args) {
                  SpringApplication.run(Application.class, args);
               }

               @Override
               protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
                   return application.sources(Application.class);
               }

               private static Class<Application> applicationClass = Application.class;

            }

=============================================== ==========================

        @RestController
        public class PersonController {

            @Autowired
            private PersonRepository personRepository;

            @RequestMapping(value = "/persons/{id}", method = RequestMethod.GET,produces={MediaType.APPLICATION_XML_VALUE},headers = "Accept=application/xml")
            public ResponseEntity<?> getPersonDetails(@PathVariable Long id, final HttpServletRequest request)throws Exception {
                Person personResponse=personRepository.findPersonById(id);
                return ResponseEntity.ok(personResponse);
            }

        }
