Question

在src / main / resources / application.conf

中

actor {
  # The guardian "/user" will use this class to obtain its supervisorStrategy.
  # It needs to be a subclass of akka.actor.SupervisorStrategyConfigurator.
  # In addition to the default there is akka.actor.StoppingSupervisorStrategy.
  guardian-supervisor-strategy = "config.ResilientSupervisorStrategy"
}

指的是以下内容：

package config

import akka.actor._
import akka.actor.SupervisorStrategy._

final class ResilientSupervisorStrategy extends SupervisorStrategyConfigurator {
  override def create(): SupervisorStrategy = {
    OneForOneStrategy(){
      case _: ActorInitializationException ⇒ Stop
      case _: ActorKilledException         ⇒ Stop
      case _: DeathPactException           ⇒ Stop
      case _: Exception                    ⇒ Resume}
    }
  }
}

我的演员实例化如此

object Singleton {
  val actorSystem = ActorSystem("main")
  val logger: ActorRef = actorSystem.actorOf(Props(new Logger()))
}

和

val miner: ActorRef = 
    Singleton.actorSystem.actorOf(Props(new Miner()))

但是，当miner遇到异常时，它仍会重新启动（它仍然使用默认的主管策略）

作为旁注，我的演员有非常简单的内部状态。所有失败都是由外部资源造成的（即由于服务器发送了错误的响应而未返回Futures），因此不需要重新启动actor的默认策略。

我认为应该是

akka.actor {
  # The guardian "/user" will use this class to obtain its supervisorStrategy.
  # It needs to be a subclass of akka.actor.SupervisorStrategyConfigurator.
  # In addition to the default there is akka.actor.StoppingSupervisorStrategy.
  guardian-supervisor-strategy = "config.ResilientSupervisorStrategy"
}
