Change the status code of a deferredResult HTTP message on timeout

I am using deferredResult

in Spring MVC but using this code the timeout still sends 503 HTTP code to the client.

future.onCompletion(new Runnable() {
    @Override
    public void run() {

        if(future.isSetOrExpired()){
            response.setStatus(HttpServletResponse.SC_NO_CONTENT);
        }
    }
});

Any idea what else to try?

I faced the same problem. My Spring MVC Controller method initially returned a DeferredResult <Object> but then I realized I wanted to control the HTTP status code. I found the answer here:

Just use DeferredResult <ResponseEntity> and you can set both the response and the Http response code in the ResponseEntity.
