java - 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，如 java.io.InputStream 或 byte[]？我希望容器绕过特定资源类或方法的任何 MessageBodyReader，但我在项目中有其他资源应该使用一些 MessageBodyReader。

我已经试过了，但是它会调用已注册的 MessageBodyReader 并且无法将结果分配给 InputStream(与 byte[] 相同的问题>).

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

我也试过这个，但是容器无法初始化并出现这个错误:

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 0SEVERE: 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();
    // ... 
}

该方法在子资源类中，该子资源类是从另一个资源类中带有 @Path 注释的方法创建的。

我正在使用 Jersey 1.11。

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();

    }
