Akka Config - application.conf - 设置Dispatcher和Router

Question

在Akka 2.2.0中,我有一个循环路由的Actor,我希望有一个自定义调度员坐在上面.

在我的application.conf拥有;

durable-dispatcher {
  mailbox-type = akka.actor.mailbox.filebased.FileBasedMailboxType
}

akka.actor.deployment {
  /notificationServiceWorkers {
    dispatcher = durable-dispatcher
    router = round-robin
    nr-of-instances = 5
  }
}

现在当我尝试创造这样的演员时;

ActorRef notificationServiceWorkers = akka.actorOf(Props.create(NotificationServiceActor.class)
   .withRouter(new FromConfig()), "notificationServiceWorkers")

调度程序未从配置中获取,它使用默认调度程序.

如果我删除了.withRouter,Akka拿起调度程序的配置就好了,但很明显它不再路由了.

如果我这样添加.withDispatcher;

ActorRef notificationServiceWorkers = akka.actorOf(Props.create(NotificationServiceActor.class)
       .withDispatcher("durable-dispatcher")
       .withRouter(new FromConfig()), "notificationServiceWorkers")

一切正常.问题是(从doco中不清楚)如果我想从application.conf加载调度程序和路由器配置那么为什么我需要在Props创建中提供这两者？这是一个错误吗？

部署未被提取的原因是路由器是作为路由器的子节点创建的,因此它们位于路径中notificationServiceWorkers/*.
