Akka 自定义主管未生效

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 Actor 是这样实例化的

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，它仍然会重新启动（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。所有失败都是由于外部资源造成的（即，Futures 没有返回，因为服务器发送了错误的响应），因此不需要重启 actor 的默认策略。

我觉得应该是

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"
}
