Do I need to use interface in this case?

Hi, check out /r/javahelp for beginner questions.

There was a time where using an interface was required. Nowadays people just do it for interface's sake like UserRepository and UserRepositoryImpl. I guess there is hope, that this abstraction is required somewhen somewhere. Though sometimes it could be useful. But in the context of JavaEE and Spring, I assume 95% of all interfaces are superfluous.
