Support for Spring WebMvc.fn

You have a note on https://springdoc.org/ saying:

Spring-weblfux with Functional Endpoints, will be available in the future release

However, I haven’t seen any mention on supporting WebMvc.fn (classic servlets): https://docs.spring.io/spring/docs/current/spring-framework-reference/web.html#webmvc-fn

Do you already have an idea on how this could be supported? Given that this approach doesn’t have a convenient place to put any annotations, I wonder how feasible it actually is.

Since the Functional Endpoints for Servlets are now pretty much stable, I am guessing that more people are going to ask for this.

As a side-note, here are two examples on how other libraries are solving this problem:

• HTTP4K is using a meta dsl
• Jooby is using a combination of build-time byte code analysis + annotation on handler functions

I don’t know much about OpenAPI, but any kind of router functions inspection should indeed use the visitor mechanism.

Great! Thank you so much 👍
