Answer 1

@RequestBody annotated parameter is expected to hold the entire body of the request and bind to one object

I think u can't have more than one RequestBody in your parameters

Answer 2

As mentioned above - you can't have 2 or more @RequestBody. I recommend creating a wrapper class that will hold these parameters from these 2 classes of yours. Also get rid of this 'logic' from your controller layer... and get rid of these ifs... consider using pattern matching from vavr library since strategy pattern seems to be overkill there
