I created a interface which has not any implementations

@Service
public interface MyInterface{


    default void doSomething{
      System.out.print("print something");
    }
}

Can MyInterface be annotated by @Autowired?

@Autowired
MyInterface myInterFace;

No you can't, because Spring tries to instantiate it to create a Bean (@Service), but it's an Interface, so thats not possible.
