我正在用Akka v2.5.23编写一个应用程序。该应用程序涉及以下参与者：

• 名为CalculatorRouter的路由器执行元类
• 名为Calculator的被路由者执行元类

我在创建Calculator actor时配置了一个PinnedDispatcher，并将log.info放在这个actor类的receive方法中。我希望在日志文件中看到线程名称字段包含pinned。但是，线程名称字段是default-dispatcher。我在日志文件中搜索了一下，发现与此log.info相关的所有线程名称都是default-dispatcher。我的代码有什么问题吗？
日志文件片段：

09:49:25.116 [server-akka.actor.default-dispatcher-14] INFO  handler.Calculator $anonfun$applyOrElse$3 92 - akka://server/user/device/$a/$a Total calc received

以下是代码片段：

class CalculatorRouter extends Actor with ActorLogging {
    var router = {
        val routees = Vector.fill(5) {
            val r = context.actorOf(Props[Calculator].withDispatcher("calc.my-pinned-dispatcher"))
            context.watch(r)
            ActorRefRoutee(r)
        }
        Router(SmallestMailboxRoutingLogic(), routees)
    }

    def receive = {
        case w:  Calc => router.route(w, sender)
        case Terminated(a) =>
            router.removeRoutee(a)
            val r = context.actorOf(Props[Calculator].withDispatcher("calc.my-pinned-dispatcher"))
            context.watch(r)
            router = router.addRoutee(r)
    }
}

calc.my-pinned-dispatcher的配置如下：

calc.my-pinned-dispatcher {
    executor="thread-pool-executor"
    type=PinnedDispatcher
  }

类计算器的源代码如下：

class Calculator extends Actor with ActorLogging {
    val w = new UdanRemoteCalculateTotalBalanceTime

    def receive = {
        case TotalCalc(fn, ocvFilepath, ratedCapacity, battCount) ⇒

                log.info(s"${self.path} Total calc received")
                Try{
                    w.CalculateTotalBalanceTime(1, fn, ocvFilepath, ratedCapacity)
                } match {
                    case Success(t) ⇒
                        val v = t.getIntData
                        sender.!(Calculated(v))(context.parent)
                    case Failure(e) ⇒ log.error(e.getMessage)
                }
    }
}

object Calculator {
    sealed trait Calc
    final case class TotalCalc(filename: String, ocvFilepath: String, ratedCapacity: String, batteryCount: Int) extends Calc
}

'20 3月4日更新
在我把akka.loggers-dispatcher = "calc.my-pinned-dispatcher"放到conf文件中之后，我在日志文件的每一行都得到了my-pinned-dispatcher-xx作为线程名。我认为线程名应该指示actor Calculator的receive方法正在执行的线程，在本例中，类似于'pinned-dispatcher-xx'的东西，因为线程是根据我的配置由固定的调度程序获得的。现在它证明了它指示了由记录器的调度程序获得的线程。如果是这种情况，如何为参与者的消息处理程序代码记录线程名称？
