如何在java play中同时停止所有调度器

import akka.actor.ActorSystem;
import play.libs.akka.AkkaGuiceSupport;

public class Global extends play.GlobalSettings implements AkkaGuiceSupport {
    @Override
    public void onStart(Application app) {
        ActorSystem actorSystem = getActorSystem();
        // 创建调度器并执行定时任务
        actorSystem.scheduler().schedule(
            Duration.Zero(),
            Duration.ofMinutes(1),
            actorSystem.actorOf(MyActor.props()),
            "message",
            actorSystem.dispatcher(),
            null
        );
    }
}

import akka.actor.ActorSystem;
import play.libs.akka.AkkaGuiceSupport;

public class Global extends play.GlobalSettings implements AkkaGuiceSupport {
    private ActorSystem actorSystem;

    @Override
    public void onStart(Application app) {
        actorSystem = getActorSystem();
        // 创建调度器并执行定时任务
        // ...
    }

    @Override
    public void onStop(Application app) {
        actorSystem.terminate();
        actorSystem.awaitTermination();
    }
}
