在AKKA中，在主管上调用关闭会阻止它监督的所有演员吗？ [英] In AKKA does calling shutdown on a supervisor stop all the actors it's supervising?

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

停止主管（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，还有另一个正确的方法，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
