Kotlin-spring generate default implementation with InterfaceOnly equals to true

[xabierMoreno]

Is your feature request related to a problem? Please describe.

I am using the generator kotlin-spring and I realised a missing functionality that java generators had.
OpenApiGenerate creates a default implementation for the methods, even that I had set up the option to interfaceOnly to be true or is there any other option that I can use?

Describe the solution you'd like

Ideally the endpotins should be created as abstract. The class that will implement the generated controller should be responsible of adding the required logic.

Describe alternatives you've considered

I cannot think another approach, but I have seen this pr related with the generator for java,
#3022

Additional context

Any help or solution will be very appreciate.

Thanks

I am using latest (5.0.0-beta2) and am able to just generate just interfaces via:

openApiGenerate {
	...
    configOptions.put("serviceInterface", "true")
}

Setting serviceInterface only applies to the service interface and not the Api interface.

    configOptions.set(
        mapOf(
            "interfaceOnly" to "true"
        )
    )

Any update on this? I was playing around with openapi-generator in a kotlin project and the generated API interface has a default inplamentation like the one provided by @xabierMoreno

V7.8
The doc says "Whether to generate only API interface stubs without the server files." and indeed it doesn't generate the SpringBoot application.

I think you're looking for serviceImplementation and/or skipDefaultInterface

Still, a lot of bugs playing with all those options. Using InterfaceOnly not only skip the Application creating but also change the requestMappingMode behavior (I need a concrete Controller but I'm stuck with an Interface :( ).
