使用Scala AKKA演员

Question

以下错误消息是我的代码：

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)) 
} 

我得到一个错误，这条线：

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

的错误是：

找不到内含价值用于参数超时：akka.util.Timeout

Answer 1

添加类似implicit val timeout = Timeout(5 seconds)的内容。见http://doc.akka.io/docs/akka/2.0.1/scala/futures.html

顺便说一句，你还需要改变

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

和

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