Obtaining raw request body in JAX-RS resource method

Question

How can I access the raw request body from a JAX-RS resource method, as java.io.InputStream or byte[]? I want the container to bypass any Mes

Answer 1

just incase this helps anyone

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();

    }

Answer 2

I found the reason that injecting HttpServletRequest did not work, it's because I did run my code in Jersey Test Framework, not within a proper Servlet container. It works if I run it in a proper Servlet container.

It is a pity that there is no pure JAX-RS way of getting the raw request body.

This works for me:

@POST
@Consumes(MediaType.WILDCARD)
@Produces(MediaType.WILDCARD)
public Response doSomething(@Context HttpServletRequest request, byte[] input) {
    log.debug("Content-Type: {}", request.getContentType());
    log.debug("Preferred output: {}", request.getHeader(HttpHeaders.ACCEPT));
}
