I have a question. At work we are currently experimenting with Kotlin and Spring Boot. One of the nice things of Java and Spring Boot was, that if you had something like "public interface EventProcessor<T>" in Java you could autowire a list of classes that implement that interface. While trying to do this today with Kotlin it didn't work. Why is that so? And is there an alternative to do a similar thing "the kotlin way"? Currently we just transform the object and based on the type we execute a different processor. This is done via a "when (x)..." but that isn't as nice.

could you share the code?
because that works in exactly the same way

[Martin Schwitalla]

will do, give me one second

[Martin Schwitalla]

this is the interface

interface EventProcessor<T> {
    
    fun process()
}

[Martin Schwitalla]

how can I properly share code? 😄

` ``` `

[Martin Schwitalla]

@Service
class SomeEventProcessor() : EventProcessor<LegacyEvent>{
    override fun process() { 
    }

}

when it's large, use insert snippet

[Martin Schwitalla]

@Service
class EventProcessorHandler(val processors: List<EventProcessor>)

[Martin Schwitalla]

then this is the code that doesn't work

[Martin Schwitalla]

In java it would have worked

[Martin Schwitalla]

any idea why?

@Martin Schwitalla Your example works for me after I fix syntax errors. Take a look at a snipped I've posted.
