特性中的Akka

我有一个扩展App的对象,我在其中创建了Actor系统和Actor Materializer,还创建了给定Actor系统下的Actor。

object QuickstartServer extends App with UserRoutes {

  implicit val system: ActorSystem = ActorSystem("helloAkkaHttpServer")
  implicit val materializer: ActorMaterializer = ActorMaterializer()

  val userRegistryActor: ActorRef = system.actorOf(UserRegistryActor.props, "userRegistryActor")


   lazy val routes: Route = userRoutes
      Http().bindAndHandle(routes, "localhost", 8080)
    }

现在UserRoutes包含了所有的路由

trait UserRoutes extends JsonSupport {

  implicit def system: ActorSystem
  lazy val log = Logging(system, classOf[UserRoutes])
  def userRegistryActor: ActorRef

  lazy val userRoutes: Route =
    pathPrefix("users") {
      concat(
        pathEnd {
          concat(
            get {
              val users: Future[Users] =
                (userRegistryActor ? GetUsers).mapTo[Users]
//Remaining code 

userRegistryActor
