Scala AKKA Actor的错误消息

发布时间：2020-12-16 08:50:07 所属栏目：安全来源：网络整理

导读：这是我的代码： 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],n

这是我的代码：

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))
}

我收到这行错误：

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

错误是：

找不到参数超时的隐含值：akka.util.Timeout

解决方法

添加隐式val timeout = Timeout(5秒)之类的内容.见 http://doc.akka.io/docs/akka/2.0.1/scala/futures.html

顺便说一下,你还需要改变

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

和

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