Elv*_*ira 9 java actor akka playframework
我正在使用Akka 2.10和JAVA.
我有一个方法,为我提供一个Actor引用 - 或者如果之前没有它,则创建一个 - 但有时当我尝试创建一个时,我收到以下异常:
akka.actor.InvalidActorNameException: actor name [<ActorName>] is not unique!
at akka.actor.dungeon.ChildrenContainer$NormalChildrenContainer.reserve(ChildrenContainer.scala:130)
at akka.actor.dungeon.Children$class.reserveChild(Children.scala:77)

当然,我知道,异常非常明确:我正在尝试使用相同的标识符创建多个actor,但是当我找不到actor的ref时,我就这样做了.及时:
private static ActorRef getActor(String id,Class actor) throws Exception{
ActorSelection sel = system.actorSelection(system.child(id));
Timeout t = new Timeout(4, TimeUnit.SECONDS);
AskableActorSelection asker = new AskableActorSelection(sel);
scala.concurrent.Future<Object> fut = asker.ask(new Identify(1), t);
ActorRef actorClient = null;
try{
//Try to get an Actor reference
ActorIdentity ident = (ActorIdentity)Await.result(fut, t.duration());
actorClient = ident.getRef();
} catch(Exception e){
System.out.println("Error:"+id);
} finally{
//IF I dont found create a new One
if(actorClient==null){
actorClient = system.actorOf(Props.create(actor),id);
//THROWS ME AN EXCEPTION
}
}
return actorClient;
}

我等了4秒没有答案......所以我创建了一个新的.
我通过解决方案搜索了我的案例,但没有成功......
任何人都可以帮我解决这个问题吗?
非常感谢!
