I'm just starting to work with Akka and I can't decide if I should use dependency injection (like cake pattern) or actor lookup in order to decouple the actors from each others. What is the preferred method?
回答1:
You should prefer to introduce actors to each other, which means to send an ActorRef in or with a message or to pass it into a constructor. The latter may involve the cake pattern of you so choose, but lookup is much more expensive and therefore you should use real ActorRef whenever possible.
