Question

我在addtional conf文件中写了我的disptacher的设置，然后将它加载到application.conf中，但是当我给出调度程序位于我的文件中的完整路径时，调度程序不工作我也确保调度程序exsits或不使用if statarements

val config = ConfigFactory.load()

      // an actor needs an ActorSystem
      val system = ActorSystem("TestActorSystem",config)
      if(system.dispatchers.hasDispatcher("akka.actor.directUserWriteMongoActor-dispatcher"))
      {println("directUserWriteMongoActor-dispatcher exists")}
      else
      {
        println("dispatcher does not exists")
      }

当我运行时，directUserWriteMongoActor-dispatcher存在于控制台上，但是当我尝试通过代码附加它时

 val DirectUserWriteMongoActor = system.actorOf(Props[DirectUserWriteMongoActor].withDispatcher("akka.actor.directUserWriteMongoActor-dispatcher"), name = "directwritemongoactorr")
      DirectUserWriteMongoActor ! DirectUserWriteToMongo(directUser)

日志表明它使用的是default-dispatcher而不是我自己的名为directUserWriteMongoActor-dispatcher的调度程序这是我的完整代码

application.conf

include "DirectUserWriteMongoActor" 

akka {
   loggers = ["akka.event.slf4j.Slf4jLogger"]
   loglevel = "DEBUG"

}

DirectUserWriteMongoActor.conf

akka {
   loggers = ["akka.event.slf4j.Slf4jLogger"]
   loglevel = "DEBUG"

  actor{
     loggers = ["akka.event.slf4j.Slf4jLogger"]
   loglevel = "DEBUG"
    ############################### Setting for a Dispatcher #####################################              
    directUserWriteMongoActor-dispatcher {
         type = Dispatcher
    executor = "fork-join-executor"
  fork-join-executor {
    parallelism-min = 2
    parallelism-factor = 2.0
    parallelism-max = 10
  }
  throughput = 10         
                  } #end default-dispatcher 

   }  #end Actor
}  #end Akka

这是我的代码

object TestActor extends App{
 val config = ConfigFactory.load()
 val system = ActorSystem("TestActorSystem",config)

      if(system.dispatchers.hasDispatcher("akka.actor.directUserWriteMongoActor-dispatcher"))
      {println("directUserWriteMongoActor-dispatcher exists")}
      else
      {
        println("directUserWriteMongoActor-dispatcher does not exists")
      }

      val DirectUserWriteMongoActor = system.actorOf(Props[DirectUserWriteMongoActor].withDispatcher("akka.actor.directUserWriteMongoActor-dispatcher"), name = "directwritemongoactorr")
      DirectUserWriteMongoActor ! DirectUserWriteToMongo(directUser)

DirectUserWriteMongoActor.scala

    case class DirectUserWriteToMongo (directuser:DirectUser) 

     class DirectUserWriteMongoActor extends Actor{

      val log = Logging(context.system, this)
     def receive = {
      case DirectUserWriteToMongo(directuser) =>
          log.debug("writing to mogo")

           log.info("message received DirectUserWriteInMongo")
           val directUserStore= new directUserStore
           log.info("going to call store in mongo")
}}

这是打印在控制台上的输出

2015-04-27 10:40:01.392 INFO  Slf4jLogger [TestActorSystem-akka.actor.default-dispatcher-2]  -Slf4jLogger started
directUserWriteMongoActor-dispatcher exists

请帮助我在我的代码或我的conf设置中有什么问题disptacher在那里，但它不起作用为什么os那么这应该打印

TestActorSystem-akka.actor.directUserWriteMongoActor-dispatcher-3

而不是

TestActorSystem-akka.actor.default-dispatcher-3

请帮助我，我第一次使用akka发送和其他配置文件

您可能正在使用SimpleLogger。此记录器使用默认调度程序进行记录。

您的代码没有任何问题。包括：println(context.dispatcher)到你的actor接收方法将通知你，他正在使用正确的directUserWriteMongoActor调度程序。

另一方面，如果将println(system.dispatcher)添加到App对象，您会发现，在actor之外使用默认调度程序。这是正确的，因为您只指定了actor的调度程序，而不是全局使用的调度程序。

akka调度员不工作
