Kotlin DSL (RouterFunctionDsl) doesn't support RenderingResponse in router function

[daggerok]

Hello all,

With java, to render template engine views i can use RouterFunction<?> in routes bean:

@SpringBootApplication
public class Application {
  @Bean RouterFunction routes(final ApplicationHandlers handlers) {
    return //...skipped
        .andOther(route(GET("/").and(accept(TEXT_HTML)), handlers::index))
        ;
  }
// main skipped..

so with that, I can use both, ServerResponse:

  Mono<ServerResponse> index(final ServerRequest request) {
    return ok().contentType(TEXT_HTML)
               .render("index", singletonMap("message", "Hello, World!"))
        ;
  }

and RenderingResponse:

  Mono<RenderingResponse> index(final ServerRequest request) {
    return create("index").modelAttribute("message", "Hello, World!")
                          .build()
        ;
  }

but unfortunately I can't do similar with Kotlin DSL:

Only Mono<ServerResponse> handler like so:

  val index: Mono<ServerResponse> by lazy {
    ok().contentType(TEXT_HTML)
        .render("index", mapOf("message" to "hey"))
  }

will works correctly... RenderingResponse extends ServerResponse, but unfortunately Mono<RenderingResponse> doesn't extend Mono<ServerResponse>

I think it's bug

Thanks for raising the issue but I'm afraid that this is the wrong tracker. The RouterFunctionDsl class is part of Spring Framework so you'll need to open an issue on jira.spring.io. If you have time, creating a small sample application that shows the problem will really help.

Hello, @philwebb

I have created that JIRA
