Question

我创建了名为CustomMailBox的自定义邮箱，该邮箱源自MyUnboundedMessageQueueSemantics个特征。然后我将这些配置放入application.conf：

custom-dispatcher {
  mailbox-requirement =
    "com.MyUnboundedMessageQueueSemantics"
}

akka.actor.mailbox.requirements {
  "com.MyUnboundedMessageQueueSemantics" =
    custom-dispatcher-mailbox
}

custom-dispatcher-mailbox {
  mailbox-type = "com.CustomMailBox"
}

akka.actor.deployment {
  /myactor {
    dispatcher = custom-dispatcher
  }
}

之后我以这种方式创建我的演员：

val system = ActorSystem("mySystem")
val quadrocopter = system.actorOf(Quadrocopter.props(vrep, clientID, handler)
        .withDispatcher("custom-dispatcher"), "myactor")

在运行我的程序后，我收到了这个错误：

有人可以解释一下我的错误吗？

Answer 1

通过在配置文件中将/myactor更改为" */myactor"来解决问题。第二步是在创建actor时删除withDispatcher()函数的调用。

自定义akka邮箱配置（Scala）
