使用Scala AKKA演員

Question

以下錯誤消息是我的代碼：

class testActor extends Actor { 
    var test = "test2" 
    def receive = { 
      case "test" ⇒ 
        "works" 
    } 
} 

def test = Action { 
    var test = "test" 
    val system = ActorSystem("MySystem") 
    val myActor = system.actorOf(Props[testActor.testActor], name = "testActor") 

    test = Await.result(myActor ? "test", Duration(1, TimeUnit.SECONDS)) 
} 

我得到一個錯誤，這條線：

test = Await.result(myActor ? "test", Duration(1, TimeUnit.SECONDS)) 

的錯誤是：

找不到內含價值用於參數超時：akka.util.Timeout

Answer 1

添加類似implicit val timeout = Timeout(5 seconds)的內容。見http://doc.akka.io/docs/akka/2.0.1/scala/futures.html

順便說一句，你還需要改變

def receive = { 
     case "test" ⇒ sender ! "works" 
} 

和

test = Await.result(myActor ? "test", timeout.duration).asInstanceOf[String]
