How can I have an Akka actor executed every 5 min?

I\'d like to know if there are any mechanism in Akka that can have an actor executed periodically?

More complete Java example:

import akka.actor.AbstractActor;
import akka.actor.ActorRef;
import scala.concurrent.duration.FiniteDuration;
import java.util.concurrent.TimeUnit;

public class AnActor extends AbstractActor {
    private final FiniteDuration SCHEDULED_WORK_DELAY = new FiniteDuration(5, TimeUnit.MINUTES);

    @Override
    public void preStart() {
        getSelf().tell("Do Scheduled Work", ActorRef.noSender());
    }

    @Override
    public Receive createReceive() {
        return receiveBuilder()
        .matchEquals("Do Scheduled Work", work -> {
            doScheduledWork();
         context().system().scheduler().scheduleOnce(SCHEDULED_WORK_DELAY, getSelf(),
                "Do Scheduled Work", context().dispatcher(), ActorRef.noSender());
        })
        .build();
    }

    private void doScheduledWork() { ... }
}
