Scala 中的预定执行器 [英] Scheduled Executor in Scala

问题描述

在 Java 中，我可以使用 ScheduledThreadPoolExecutor 来安排在给定延迟后运行的任务.我可以在 Scala 中使用它，但我想知道是否有 Scala API.

In Java I can use Scheduled Executor to schedule tasks to run after a given delay. I can use it in Scala but I wonder if there is a Scala API for that.

是否有任何 Scala API(相对于 Java 中的 Scheduled Executor)来安排任务?

Is there any Scala API (as opposed to Scheduled Executor in Java) to schedule tasks?

推荐答案

Akka 有一些类似调度器的东西:

Akka has something similar with schedulers:

http://doc.akka.io/api/akka/2.1.4/#akka.actor.Scheduler

你可以从actor系统中获取:

You can obtain one from the actor system:

val actorSystem = ActorSystem()
val scheduler = actorSystem.scheduler
val task = new Runnable { def run() { log.info("Hello") } }
implicit val executor = actorSystem.dispatcher

scheduler.schedule(
  initialDelay = Duration(5, TimeUnit.SECONDS),
  interval = Duration(10, TimeUnit.SECONDS),
  runnable = task)

如果你正在使用 Akka 或基于它的东西，比如 Play，那就是要走的路.

If you are using Akka or something based on it, like Play, that would be the way to go.
