How to correctly schedule task in Play Framework 2.4.2 scala?

Question

Trying to schedule tasks like this in Play Framework 2.4.2 Scala without luck:

import akka.actor.Actor
import play.api.libs.concurrent.Akka
import scala.conc         


        

Answer 1

Ok. Here working code of scheduler I've built: Module:

class JobModule extends AbstractModule with AkkaGuiceSupport {
  def configure() = {
    bindActor[SchedulerActor]("scheduler-actor")
    bind(classOf[Scheduler]).asEagerSingleton()
  }
}

Scheduler:

class Scheduler @Inject() (val system: ActorSystem, @Named("scheduler-actor") val schedulerActor: ActorRef)(implicit ec: ExecutionContext)
{
  system.scheduler.schedule(
    0.microseconds, 5.minutes, schedulerActor, "update")
  system.scheduler.schedule(
    30.minutes, 30.days, schedulerActor, "clean")
}

Actor:

@Singleton
class SchedulerActor @Inject() (updater: Updater) extends Actor {
  def receive = {
    case "update" => updateDB()
    case "clean" => clean()
  }

  def updateDB(): Unit ={
    Logger.debug("updates running")
  }

  def clean(): Unit ={
    Logger.debug("cleanup running")
  }
}

You also need to add your module in application.conf:

play.modules.enabled += "modules.JobModule"

Hope this will help someone
