I wanna to know the best approach to use Controller, Facade, Service, Repository in Spring MVC.
The structure in my current project is:
AController -> AService(business logic in here) -> ARepository
BController -> BService(business logic in here) -> BRepository
and other CDE... Controller, Service, Repository
But when business logic get complicated, I don't know which design is correct:
1. AController -> AService & BService & ...CDE Service
2. AController -> AService -> BCD Service
3. AController -> AFacade -> ABCD... Service
And if I choose the answer 3, can I still use its own Service as below?
AController -> AFacade -> ABCD... Service
AController -> AService
Or I can't invoke the AService from AController anymore but invoke by AFacade only?
Thanks for answer.
