Custom operation filters

Is your feature request related to a problem? Please describe. We have little library for api versioning that generates custom RequestCondition depending on special annotation. So we can write controllers like this:

@RestController
public class Controller {
    @Versioner(till = 0)
    @GetMapping("/test")
    public String old() {
        return "old";
    }

    @Versioner(from = 1)
    @GetMapping("/test")
    public Integer other() {
        return 123;
    }
}

Then GET /v0/test returns "old" and GET /v1/test returns 123

Now we need openapi to produce 2 groups: group v0 with GET /test endpoint that produces String and group v1 with GET /test endpoint that produces Integer

Describe the solution you’d like Something like addCustomFilter in GroupedOpenApi.Builder where I can use handlerMethod.getMethodAnnotation(Versioner.class) to determine, if this method should be displayed in this group

Describe alternatives you’ve considered

• I have tried to filter paths in OpenApiCustomiser, but when it is called, there is already only one endpoint because the others have been overwritten here due to identical operationPath (/test)

@romash1408 Did you find a solution for this?

I have been trying for 2 days now to make springdoc filter out the right controllers for the specific (version) groups but havent succeeded yet. It always seem to have merged methods from multiple versioned controllers into the same operations before I can get to them with OpenApiCustomizer because they have the same path and signature.

@Hidden annotation don’t let me filter operation only in certain groups. I need to select operations for group depending on my custom annotation.
