在AKKA中，在主管上调用关闭会阻止它监督的所有演员吗？

Question

Let's say I have a supervisor that has linked 2 actors. When my app shutsdown I want to shutdown those actors gracefully. Does calling supervisor.shutdown() stop all the actors or do I still need to stop my actors manually?

gracias

Answer 1

Stopping a supervisor (calling Supervisor.stop() ) stops all linked (supervised) actors:

final class SupervisorActor{
...
   override def postStop(): Unit = shutdownLinkedActors

However, when you want to shutdown all actors in the system gracefully, there's another proper way to do that , using Actor Registry (that holds information about all the actors systemwide):

Actor.registry.shutdownAll
