how would you call UserServiceImpl? Underlying question, how would you organize your CRUD (with business logic) operations?

I think I would reverse the question. Why does there have to be a UserService interface? If it only exists in order to be mocked in yet another place of the code you've added even more unnecessary layering in your codebase.
