[REQ] [kotlin-spring] Reactive Kotlin Spring Server Generator

[botcoder]

Describe the solution you'd like

Support webflux in the same way as the Spring server generator, when using kotlin-spring with spring-boot library.

Describe alternatives you've considered

Wrap ResponseEntity with Mono/Flux.

Additional context

Java support was added at PR #571, but Kotlin support is missing.

@botcoder that's a reasonable suggestion. May I know if you've time to contribute the enhancement? We can show you some good starting points.

since spring 5.2 support kotlin coroutines, i'm interesed to add reactive behavior with coroutines for kotlin-spring generator. should i start from @botcoder work ?

You can ignore my change as I just added a "Mono/Flux" wrapper, but it's incomplete as it doesn't allow the user to change the response headers, and adding a reference to ServerWebExchange doesn't work on webflux, so I closed the pull request.

Coroutine would be a much better solution, I'll be looking forward to it. Thank you.

I will add a reactive support via coroutines then. should I also remove any reference to mono/flux that are already in the master ? (in the template there a reference to reactive but they cannot be triggered because there is no reactive option in the kotlin-spring at the moment)

[botcoder]

It seems those references were added by mistake (ie, copy+paste from spring-mvc, perhaps).

since the PR #2934 is merged, shouldn't this request be closed?
