Question

我按照CappedCollection演示示例获得了一个Iteratee，消耗了Play 2.2的上限集合，没有任何问题。升级到Play 2.3后，我在尝试阻止Iteratee时遇到了一些奇怪的问题。当游戏关闭时，我挂钩到onStop并尝试停止iteratee购买呼叫运行，但无论在Await上什么，我总是遇到超时。这也发生在我使用withApplication的单元测试中。直到升级到2.3并且到reactivemongo / play2-reactive mongo“0.10.5.0.akka23”，这才能完美运行。最初，我认为Play首先关闭Akka可能是一个问题，但我已经确认ReactiveMongoPlugin设置为1200，应该在Akka之前关闭。

任何帮助将不胜感激！

Mongo版本2.6.3

Here is my setup code 
//Some JSONCollection

           collection
           .find(Jons.obj())
           .hint(Json.obj("$natural" -> 1))
           .options(QueryOpts().tailable.awaitData)
          .cursor[Model])

        val enumerator = cursor.get.enumerate()

        iteratee = Iteratee.flatten(enumerator |>> process())
    }

    //Iteratee returned for 
    def process(): Iteratee[Model, Unit] = {
    Iteratee.foreach { model =>

          //Do something with model class
          process(model)
        }

    //Called by Global.onStop()
    def stop(): Unit=  {

        val result = iteratee.run.andThen {
          case r => saveIndex()
         } andThen {
            case Success(x) => Logger.info("Successful exit iteratee")
            case Failure(ex) => Logger.error("", ex)
         }

       //This always times out on shutdown
       Await.result(f, 10 seconds)


    }

//例外
