Spring Reactive request and response in SpEL expression within @MVC annotations [SPR-14535]

Rossen Stoyanchev opened SPR-14535 and commented

Currently we have annotated controller method arguments, e.g. @PathVariable, @RequestParam, @RequestHeader, CookieValue, @Value, etc. Many of them support SpEL expressions and those should support expressions referring to the request, response, and possibly the exchange.
