Akka石英调度程序不会触发作业

本文介绍了Akka石英调度程序不会触发作业的处理方法，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

我尝试在我的游戏项目中使用 akka-quartz-scheduler 。 我创建了两个akka演员，并为演员添加了配置：

I try to use this akka-quartz-scheduler in my play project. I created two akka actors, added configuration for actors:

akka { quartz { schedules { HELLO_ACTOR { description = "A cron job that fires off every 10 seconds" expression = "0/10 0 0 ? * * *" } CLEANUP_ACTOR { description = "A cron job that fires off every 10 seconds" expression = "0/10 0 0 ? * * *" } } } }

我创建了模块，并在调度器和绑定调度器的地方添加了调度器：

I created module and add scheduler where i bind actors and scheduler:

protected void configure() { bindActor(HelloActor.class, HelloActor.NAME); bindActor(CleanupRunner.class, CleanupRunner.NAME); bind(QuartzSchedulerHelper.class).asEagerSingleton(); bind(QuartzSchedulerExtension.class).toProvider(SchedulerJobInitializer.class); } private static class SchedulerJobInitializer implements Provider<QuartzSchedulerExtension> { private final QuartzSchedulerExtension quartzSchedulerExtension; @Inject public SchedulerJobInitializer(ActorSystem actorSystem) { this.quartzSchedulerExtension = new QuartzSchedulerExtension((ExtendedActorSystem) actorSystem); } @Override public QuartzSchedulerExtension get() { return quartzSchedulerExtension; } }

应用程序启动时，我在日志中看到参与者已添加到调度程序中：

When application starts, I see in the log that actors were added to scheduler:

2018-07-06 11:51:44,947 [INFO] from org.quartz.impl.DirectSchedulerFactory in play-dev-mode-akka.actor.default-dispatcher-2 - Quartz scheduler 'QuartzScheduler~application 2018-07-06 11:51:44,947 [INFO] from org.quartz.impl.DirectSchedulerFactory in play-dev-mode-akka.actor.default-dispatcher-2 - Quartz scheduler version: 2.2.3 2018-07-06 11:51:44,950 [INFO] from org.quartz.core.QuartzScheduler in play-dev-mode-akka.actor.default-dispatcher-2 - Scheduler QuartzScheduler~application_$_application started. 2018-07-06 11:51:44,974 [INFO] from com.typesafe.akka.extension.quartz.QuartzSchedulerExtension in application-akka.actor.default-dispatcher-2 - Setting up scheduled job 'HELLO_ACTOR', with 'com.typesafe.akka.extension.quartz.QuartzCronSchedule@6a6c7b3b' 2018-07-06 11:51:45,005 [INFO] from com.typesafe.akka.extension.quartz.QuartzSchedulerExtension in application-akka.actor.default-dispatcher-2 - Setting up scheduled job 'CLEANUP_ACTOR', with 'com.typesafe.akka.extension.quartz.QuartzCronSchedule@2c32247d'

应该每10秒钟触发一次。任何不起作用的原因，或者我应该在什么地方添加？

Acotrs should be triggered every 10 seconds. Any reason why this do not work, or what should I add and where?

这里是 github上的代码。

推荐答案

您的日志摘要并不表示您的演员已在调度程序中注册。它显示的是Quartz作业已成功调度：在您的配置中， akka.quartz.schedules.HELLO_ACTOR 和 akka.quartz.schedules。 CLEANUP_ACTOR 是工作，而不是演员，尽管您已将其命名。 （我建议重命名这些作业以避免混淆。）

Your log snippet does not indicate that your actors are registered with the scheduler. What it does show is that the Quartz jobs are successfully scheduled: in your configuration, akka.quartz.schedules.HELLO_ACTOR and akka.quartz.schedules.CLEANUP_ACTOR are jobs, not actors, despite what you've named them. (I recommend renaming those jobs to avoid confusion.)

考虑您的 QuartzSchedulerHelper ，看来您的演员不是已向调度程序注册：

Considering your QuartzSchedulerHelper, it doesn't appear that your actors are registered with the scheduler:

List<String> actors = Arrays.asList(HelloActor.NAME, CleanupRunner.NAME); for (String name : actors) { ActorRef actor = registry.actorFor(name); schedule(quartzSchedulerExtension, actor, name, RandomStringUtils.randomAlphabetic(10)); }

actorFor 演员路径作为参数。您要传递给该方法的是演员的名字。使用actor路径：

actorFor takes an actor path as an argument. What you're passing to that method is the actor's name. Use the actor path:

String actorPath = "/user/" + name ActorRef actor = registry.actorFor(actorPath)

您可能还想尝试以下actor路径：

You might also want to try the following actor path:

String actorPath = "akka://application/user/" + name
