scala – Akka：发送未来的消息给Actor

def receive = {
    case All() => {
        val collection: BSONCollection = db("ping")
        val future:Future[List[Ping]] = collection.find(BSONDocument()).cursor[Ping].toList()
        val zender = sender
        future onComplete {
            case Success(list) => zender ! list
            case Failure(throwable) => zender ! List()
        }
    }
}

我不喜欢如何使用onComplete函数将结果发送回发送者actor.我想知道是否可以将其转换成如下所示：

def receive = {
    case All() => {
        val collection: BSONCollection = db("ping")
        val future:Future[List[Ping]] = collection.find(BSONDocument()).cursor[Ping].toList()
        "sender ! future" // one option
        "future.map( list => sender ! list)" //Another option. I know it's not map,but maybe another function        
    }
}

我觉得随着未来的链接,这会更好.
