No way to signal that controller has handled the request in Webflux [SPR-16087]

[spring-projects-issues]

Dave Syer opened SPR-16087 and commented

Actually this appears to work:

@GetMapping("/flux")
@ResponseBody
Mono<Void> flux(ServerWebExchange exchange) throws Exception {
    // write the response using exchange ... 
}

but as far as I can tell it's undocumented, so I'm not sure if it is correct.
