Scala Akka-群集感知路由器不'；t启动节点

我需要创建一个由3个节点组成的集群，其中每个节点将运行一个actor-

TestActor

的实例。我希望路由器将自己创建节点（池），但它创建的第一个节点将是种子节点，因为路由器将是集群中创建的第一个参与者

这是我的代码TestActor.scala：

import akka.actor.{Actor, ActorLogging, ActorSystem, Props}
import akka.cluster.Cluster
import akka.routing.FromConfig
import com.typesafe.config.ConfigFactory
import akka.pattern.ask
import akka.util.Timeout
import scala.concurrent.ExecutionContext.Implicits.global

object TestActor {
  def main(args: Array[String]) {
    val system = ActorSystem("mySys", ConfigFactory.load("test"))
    val testActor = system.actorOf(Props(classOf[TestActor]).withRouter(FromConfig()),"TestActor")
    implicit val t = Timeout(60 * 1000)
    println((testActor ? "hello").onSuccess{
      case x=> println(x)
    })
  }
}
class TestActor extends Actor with ActorLogging {

  Cluster(system)

  override def postStop(): Unit = {
    log.info(s"Stopping actor on path ${self.path}")
    super.postStop()
  }

  override def preStart(): Unit ={
    log.info(s"Starting actor on path ${self.path}")
    super.preStart()
  }

  override def receive : Receive = {
    case x => {
     log.info(s"actor : ${self.path} GOT MESSAGE  $x")
     sender() ! x
   }
  }

}

和test.conf：

   akka {
   cluster {
     auto-down-unreachable-after = 20s
     seed-nodes = [
       "akka.tcp://mySys@127.0.0.1:2552"
     ]
   }
   actor {
     provider = "akka.cluster.ClusterActorRefProvider"

     deployment {
       /TestActor {
         router = round-robin-pool
         nr-of-instances = 3
         cluster {
           enabled = on
           max-nr-of-instances-per-node = 1
           allow-local-routees = off
         }
       }
     }
   }
 }

然后当我运行程序时，我看不到任何打印，消息变成死信

以下是日志：
