Play 2.1.1无法加载自定义的Akka调度程序

Question

我正在使用Play 2.1.1，在application.conf中我添加了以下自定义分发器：

# Dispatcher for round-robin actors
play {
    akka {
        actor {
            rr-dispatcher = {
                type = BalancingDispatcher
                executor = fork-join-executor
                fork-join-executor {
                    parallelism-min = 2
                    parallelism-factor = 2
                    parallelism-max = 24
                }
                # messages per actor before jumping
                throughput = 100
            }
        }
    }
}

我尝试在演员上使用它：

private val default = Akka.system.actorOf(Props[MessageRouterActor].withRouter(FromConfig()).withDispatcher("rr-dispatcher"), "msgRouter")

但是我收到了这个消息，提示找不到调度程序：

[info] play - Starting application default Akka system.
[WARN] [04/20/2013 22:05:12.069] [application-akka.actor.default-dispatcher-5] [Dispatchers] Dispatcher [rr-dispatcher] not configured, using default-dispatcher

据我所见，这似乎是添加它的正确方式。有人知道问题出在哪里吗？

您需要提供完整的配置值路径：使用withDispatcher("akka.actor.rr-dispatcher")（或者甚至是"play.akka.actor.rr-dispatcher"）
