Question

根据此链接中的程序： Java Akka's ActorRef async issues

是否有任何Akka本机函数可用作actor.tell的调度函数？我想安排每个时间间隔自动“告诉”。

顺便说一句，我不选择Java的Executor，因为我不想浪费OS资源。

附上示例代码：

ActorSystem as1 = ActorSystem.create("actor1");
ActorRef ar1 = as1.actorOf(Props.create(Hello.class), "ar1");
ActorRef ar2 = as1.actorOf(Props.create(Hello.class), "ar2");
Router router = new Router(new RoundRobinRoutingLogic());
router = router.addRoutee(ar1);
router = router.addRoutee(ar2);
System.out.println("Start to say hello!");
router.route("Bob",ActorRef.noSender());
router.route("John",ActorRef.noSender());
System.out.println("Finish to say hello!”);

这个section in the reference guide应该对此非常有帮助。在演员中，您可以执行以下操作：

FiniteDuration delay = FiniteDuration.create(10, TimeUnit.MINUTES);
FiniteDuration initialDelay = FiniteDuration.create(2, TimeUnit.MINUTES);
getContext().system().scheduler().schedule(initialDelay, delay, self(), message, getContext().dispatcher(), ActorRef.noSender());

如果你有一个ActorRef ref

，你可以从演员外面做一些类似的事情

FiniteDuration delay = FiniteDuration.create(10, TimeUnit.MINUTES);
FiniteDuration initialDelay = FiniteDuration.create(2, TimeUnit.MINUTES);
actorSystem.scheduler().schedule(initialDelay, delay, self(), message, actorSystem.dispatcher(), ActorRef.noSender())

使用路由器：

ActorSystem as1 = ActorSystem.create("actor1");
ActorRef ar1 = as1.actorOf(Props.create(Hello.class), "ar1");
ActorRef ar2 = as1.actorOf(Props.create(Hello.class), "ar2");
List<String> routees = Arrays.asList(ar1, ar2);
ActorRef routerActorRef = as1.actorOf(new RoundRobinGroup(routees).props(), "router");
System.out.println("Start to say hello!");

FiniteDuration delay = FiniteDuration.create(10, TimeUnit.MINUTES);
FiniteDuration initialDelay = FiniteDuration.create(2, TimeUnit.MINUTES);
as1.scheduler().schedule(initialDelay, delay, routerActorRef, "Bob", as1.dispatcher(), ActorRef.noSender())

as1.scheduler().schedule(initialDelay, delay, routerActorRef, "John", as1.dispatcher(), ActorRef.noSender())

System.out.println("Finish to say hello!”);
