Question

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

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 ? * * *"
      }
    }
  }
}

我创建了模块并添加了调度器，以便在其中绑定actor和调度器：

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：

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

应该每10秒触发一次幻觉。有什么原因不起作用，或者我应该在哪里添加？

您仍然需要在代码中进行计划，以声明需要发送哪些消息以及向哪个参与者发送消息。在Scala中，您可以这样做：

QuartzSchedulerExtension(context.system).schedule("HELLO_ACTOR", someActor, "Hello from the Quartz scheduler")
QuartzSchedulerExtension(context.system).schedule("CLEANUP_ACTOR", someOtherActor, "Clean up from the Quartz scheduler")

如果要停止其中之一，可以使用方法cancelJob：

QuartzSchedulerExtension(context.system).cancelJob("HELLO_ACTOR")

Answer 2

您的日志片段并不表示您的演员已在调度程序中注册。它确实表明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是作业，而不是参与者，尽管您已将其命名。（我建议重命名这些作业以避免混淆。）

考虑到您的QuartzSchedulerHelper，看来演员没有在调度程序中注册：

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

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

您可能还想尝试以下演员路径：

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

Akka石英调度程序不会触发作业
