i am creating child actors via ActorRefFactory so that i can inject it
i am using one-for-one supervision strategy for these child actors but when they throw the exception i can not able to see in the logs that supervision startegy is working as i set it to Resume
here is my code
val system = actorInjector.getInstance(classOf[ActorSystem])
val eventWriteActor = (f:ActorRefFactory) => f.actorOf(Props(new EventWriteActor(insertService)),"eventWriteActor")
val actorsList:List[ActorRefFactory=>ActorRef]=List(eventWriteActor,eventQueryActor)
val actorManager: ActorRef = system.actorOf(Props(new ActorManager(actorsList)), name = "ActorManager")
ActorManager.scala //parent actor
class ActorManager(childMaker: List[ActorRefFactory => ActorRef]) extends Actor {
val seconds = 10
var eventWriteActor: Option[ActorRef] = None
var eventQueryActor: Option[ActorRef] = None
override val supervisorStrategy = OneForOneStrategy(
maxNrOfRetries = seconds, withinTimeRange = seconds seconds) {
case mex: MongoException =>
log.error("Got some MongoException, Supervision Strategy says Resume exception is {}",mex)
Resume
case e: Exception =>
log.error("Got some Exception, Supervision Strategy says Resume exception is {}",e)
Resume
}
if (childMaker.nonEmpty) {
eventWriteActor = Some(childMaker(0)(context))
eventQueryActor = Some(childMaker(1)(context))
}
def receive: PartialFunction[Any, Unit] = {
case InsertEvent(event) =>
eventWriteActor match {
case Some(writeActor)=>
ask(writeActor, InsertEventInMongo(event)).pipeTo(sender)
case None=>log.info("eventWriteActor is empty")
}
}
}
child actor
class EventWriteActor @Inject() (insertEventServiceTrait:InsertEventServiceTrait) extends Actor {
def receive: PartialFunction[Any, Unit] = {
case InsertEventInMongo(event) =>
senderRef = Some(sender)
insertEventServiceTrait.insertEventInMongo(event,senderRef)
}
}
service class
class InsertEventService @Inject()(eventRepo: EventRepository) extends InsertEventServiceTrait {
override def insertEventInMongo(event: Event, senderRef: Option[ActorRef]): Unit = {
eventRepository.insertEvent(event: Event, senderRef: Option[ActorRef])
}
}
repository class
class EventRepositoryImpl @Inject()(mongodb: MongoFactoryTrait) extends EventRepository {
val eventInsert = new EventInsert(mongodb)
override def insertEvent(event: Event, senderRef: Option[akka.actor.ActorRef]): Unit = {
eventInsert.eventInsert(event: Event, senderRef: Option[akka.actor.ActorRef])
}
}
domain class
class EventInsert(mongoFactoryTrait: MongoFactoryTrait) {
def eventInsert(event: Event, senderRef: Option[akka.actor.ActorRef]):Unit = {
var isInserted: Boolean = false
val document = insertDocument(event)
val collection: MongoCollection[Document] = mongoFactoryTrait.collectionMongo(Event_COLLECTION_NAME)
val insertionResult: SingleObservable[Completed] = collection.insertOne(document)
insertionResult.subscribe(new Observer[Completed] {
override def onNext(result: Completed): Unit = {
log.info("insertEvent: Event successfully inserted")
isInserted = true
}
override def onError(e: Throwable) = {
isInserted = false
e match {
case mongoEx: MongoException =>
log.error("insertEvent: Mongoexception in inserting Event", mongoEx)
senderRef match {
case Some(ref: ActorRef) =>
ref ! akka.actor.Status.Failure(mongoEx)
case None => log.warn("insertEvent: Actor reference is null")
}
case e: Exception =>
isInserted = false
log.debug("insertEvent: Event record not inserted, isInserted ={}", isInserted)
senderRef match {
case Some(ref: ActorRef) =>
ref ! akka.actor.Status.Failure(e)
case None => log.warn("insertEvent: Actor reference is null")
}
}
}
override def onComplete(): Unit = {
isInserted = true
senderRef match {
case Some(ref: ActorRef) =>
ref ! isInserted
case None => log.warn("insertEvent: Actor reference is null")
}
}
})
}
i am adding a document with same key so that the code throws MongoDublicateKey exception and i can test the code but here are the logs i got it does not show supervisor actor in actor
