Question

Say I have 2 service classes:

UserService
ProductService

Is it wrong if within my ProductService class I inject the UserService?

public class ProductserviceImpl implements ProductService {


  @Autowired
  UserService userService;


  @Override
  public void someThing() {
      ..
      userService.otherThing(..);
      ..
  }

}

I know as an alternative I could create yet another class that injects both UserService and ProductService, but coming up with a name for this class is very tricky 🙂 Is there a name for these types of classes in the SOA world?

Answer 1

For me, there’s no problem to inject a service into another one. That’s the point with services and SOA as you said.

Services can help each others in order to give you the final result. Besides, as told JB Nizet, if there is no cyclic dependencies, no problem.
