Send Async Response while my controller api method being Void ( javax @AsyncResponse style)

[subash89]

Hi,
Is there a way I can keep my api method void, but use kind of a handler I can use later downstream in my code to send the response.
Example:
Usually I would have following.

    public Publisher< MyResponse.class > post() {
        return Mono.from(client.retrieve(url), MyResponse.class));
    }

Instead expected following. Here mysvc.invoke() method will call say a backend api in an async manner and send a Publisher to the client.

    public void post() {
        mysvc.invoke()
    }

Main reason is we have some apis uses javax AsyncResponse where you can keep a void api method and send response later.
This is to support similar behavior for such written code.

Appreciate any input.

i mean, you can use Mono.create(sink -> ...)
