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

Try

context.system.scheduler.schedule

And also make sure you have logging at Debug level otherwise those messages won't make it to the console. If you're unsure try changing them to Logger.error temporarily.

Answer 2

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
