Akka-http:如何将响应映射到对象

import akka.actor.ActorSystem
import akka.http.scaladsl.Http
import akka.http.scaladsl.server.Directives._
import akka.http.scaladsl.server.Route
import akka.stream.ActorMaterializer

// 定义一个对象
case class User(id: Int, name: String)

object Main extends App {
  implicit val system = ActorSystem("my-system")
  implicit val materializer = ActorMaterializer()
  implicit val executionContext = system.dispatcher

  // 定义路由
  val route: Route = path("user") {
    get {
      // 将响应映射到对象
      complete(User(1, "John Doe"))
    }
  }

  // 启动HTTP服务器
  val bindingFuture = Http().bindAndHandle(route, "localhost", 8080)
}
