Akka 2.1.2 Scheduler有问题（无法识别“系统”）

本文介绍了Akka 2.1.2 Scheduler有问题（无法识别“系统”）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

根据这些示例，我正在尝试运行一个非常简单的循环函数循环：

I'm trying to get a very simple recurring function loop running, according to these samples:

doc.akka.io/docs/akka/2.1.2/scala/scheduler.html

代码：

import akka.actor.Actor import akka.actor.Props import scala.concurrent.duration._ object Main extends Application { val system = akka.actor.ActorSystem("system") // this was missing! import system.dispatcher system.scheduler.schedule( 0 milliseconds, (10*1000) milliseconds, { println( "click!" ) }) }

我得到（sbt）：

> .../src/Main.scala:34: not found: value system [error] import > system.dispatcher [error] ^ [error] > .../src/Main.scala:36: not found: value system [error] > system.scheduler.schedule( 0 milliseconds /*initial delay*/, > (entry.secs*1000) milliseconds /*delay between*/, { [error] ^

系统应该来自哪里？

附录：

我在'main（）'函数中包含代码，并且我没有不能从 Actor 或 ActorSystem 继承任何东西。重点是我想安排函数，但不参与Actor

I'm having the code within a 'main()' function, and I haven't inherited anything from Actor or ActorSystem. The point is I'd like to schedule functions but no go into actors with this. Is the framework thinking I must derive from something (if so, it kind-of should say it?).

推荐答案

在 import system.dispatcher 之前似乎缺少以下表达式：

It looks like missing of following expression before import system.dispatcher:

val system = akka.actor.ActorSystem("system")
