在JAX-RS资源方法中获取原始请求体

Question

如何从JAX-RS资源方法访问原始请求主体，例如java.io.inputstream或byte[]？对于特定的资源类或方法，我希望容器绕过任何MessageBodyReader，但是项目中有其他资源应该使用一些MessageBodyReader。

我已经尝试过了，但是它将调用注册的MessageBodyReaders并且无法将结果分配给InputStream(Byte[])。

@POST
public Response post(@Context HttpHeaders headers, InputStream requestBody) {
    MediaType contentType = headers.getMediaType();
    // ... 
}

SEVERE: The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Missing dependency for method public javax.ws.rs.core.Response SomeResource.post(javax.servlet.http.HttpServletRequest) at parameter at index 0
SEVERE: Method, public javax.ws.rs.core.Response SomeResource.post(javax.servlet.http.HttpServletRequest), annotated with POST of resource, class SomeResource, is not recognized as valid resource method.

@POST
public Response post(@Context HttpServletRequest request) {
    String contentType = request.getContentType();
    InputStream requestBody = request.getInputStream();
    // ... 
}

以防万一这对任何人都有帮助

public Response doAThing(@Context HttpServletRequest request, InputStream requestBody){


        BufferedReader reader = new BufferedReader(new InputStreamReader(requestBody));
        StringBuilder out = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            out.append(line);
        }
        System.out.println(out.toString());   //Prints the string content read from input stream
        reader.close();

        return Response.ok().entity("{\"Submit\": \"Success\"}").build();

    }
