Springboot REST应用程序应接受并生成XML和JSON

Question

我正在开发Springboot REST API。我的应用程序应该同时使用和生成XML和JSON。我遇到了Jackson json Xml依赖项。

    <groupId>com.fasterxml.jackson.dataformat</groupId>
        <artifactId>jackson-dataformat-xml</artifactId>
        <version>2.5.4</version>
    </dependency>

我在我的pom.xml.中添加了这个，现在我可以接受xml输入，但是当映射到Java对象时，这些值为空。以下是我的资源类。

@Configuration
@ImportResource("/application-context.xml")
@EnableAutoConfiguration
@ResponseBody
@RequestMapping("/match")
public class MatchResource {

    private static final Logger logger = LogManager.getLogger(MatchResource.class);

    @Autowired
    private MatchService matchService;

    @RequestMapping(method = RequestMethod.POST)
    @Consumes({MediaType.TEXT_XML,MediaType.APPLICATION_JSON})
    @Produces({MediaType.TEXT_XML,MediaType.APPLICATION_JSON})
    //@Produces( MediaType.APPLICATION_XML)
    public Response matchRequest(@RequestBody MatchRequest matchRequest,
                                 @Context HttpServletRequest headers) throws Exception {

        Response resp = null;
        MiniMatchResponse output = null;

        // Headers are store in the "headers" object. To retrieve a specific header, please take a look at the below statement
        String apiUser = headers.getHeader("Api-User");

        UUID randID = UUID.randomUUID();

        logger.info("Get Match for with ID: " + randID);

        // Get service profile from headers via MatchConstants.SERVICE_PROFILE_HEADER
        String serviceProfile = "";

        try {

            //TODO: MatchService should return MatchResponse Object

            //Json OutPut
            output = matchService.findResponse(matchRequest, serviceProfile);

            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            factory.setNamespaceAware(true);

            logger.debug("Match Request: " + matchRequest.toString());
        } catch (ErrorException e) {
            logger.error(e.getMessage(), e);
         }
         // Form Response
        resp = Response.status(200).entity(output).build();

        return resp;
    }

下面是我的请求对象

JSON请求和响应工作正常。您能帮助我如何在我的应用程序中包含XML请求和响应吗。

尝试将带有用作根标记的标记的@XmlRootElement（name=“myRootTag”）JAXB注释添加到类MatchRequest。在REST请求中同时使用XML和JSON作为传输格式，但使用moxy而不是Jackson时，我遇到了类似的问题。在任何情况下，正确的JAXB注释都是转换为XML或从XML转换过来所必需的（XML在这方面比JSON更挑剔）。

Jackson XML应该支持JAXB注释，如果这不起作用，它有自己的一组与JAXB不兼容的类似注释（参见https://github.com/FasterXML/jackson-dataformat-xml和https://github.com/FasterXML/jackson-dataformat-xml/wiki/Jackson-XML-annotations）
