问题描述
假设我有一位主管已经联系了两位演员。当我的应用程序关闭时，我想优雅地关闭这些演员。调用supervisor.shutdown（）会停止所有演员还是我还需要手动停止我的演员？
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
推荐答案
（调用 Supervisor.stop（））停止所有链接（受监督）演员：
Stopping a supervisor (calling Supervisor.stop()) stops all linked (supervised) actors:
final class SupervisorActor{
...
override def postStop(): Unit = shutdownLinkedActors
但是，如果要优雅地关闭系统中的所有actor，还有另一个，使用Actor Registry（包含系统范围内所有演员的信息）：
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
