Question

我知道我的客户工作，因为我发布到另一个网站，这一切都有效。我将客户端更改为发布到网址http://localhost:9000/enrollment/enroll并运行以下服务器...

@Path("/enrollment")
public class MockHpsRestApi {

    private static final Logger log = LoggerFactory.getLogger(MockHpsRestApi.class);

    public static void main(final String[] args) throws InterruptedException,
            IOException, MuleException {
        log.info("starting the server");
        JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
        sf.setResourceClasses(MockHpsRestApi.class);
        sf.setResourceProvider(MockHpsRestApi.class, new SingletonResourceProvider(new MockHpsRestApi()));

        sf.setAddress("http://0.0.0.0:9000/");

        sf.create();
    }

    @POST
    @Path("/enroll")
    @Consumes("application/xml")
    public String enrollment(MultipartBody body) throws IOException {
        log.info("received request="+body);
        Attachment att = body.getRootAttachment();
        ByteArrayOutputStream str = new ByteArrayOutputStream(100);
        InputStream in = att.getDataHandler().getInputStream();
        try {
            IOUtils.copy(in, str);

            log.info("body payload received="+str);
            String xml = "success";
            return xml;
        } finally {
            IOUtils.closeQuietly(in);
            IOUtils.closeQuietly(str);
        }
    }
}

我的日志会在收到请求时说出来......

为什么这不起作用？

嗯，提高日志级别，这是CXF中的某种错误，虽然这意味着没有人真正做基本的帖子，所以这似乎不对....（再一次，我的客户发帖很好到今天的另一项服务）。

Answer 1

当使用@POST和@Consumes("application/xml")时，方法上的（单个未注释的）参数类型是正常的，这是一个JAXB注释的类，CXF会在将XML转换为之前对其进行反序列化您。有没有特别的理由不去那条旅游路线？

Answer 2

调试代码后，事实证明您可以使用以下类型作为上述方法的参数。

Source
XMLSource
Document
byte[]
InputStream

我最终使用InputStream。

JAXRS / CXF为什么这个简单的帖子示例不起作用
