이 문제를 해결하기 위해 serializer/deserializer를 작성해야하지만 정확하게는 알 수 없습니다. 리프트 웹 프레임 워크를 사용하는 몇 가지 예가 있지만 그 중 하나가없는 것은 아닙니다. 이 작업을 수행하는 방법에 대한 도움이 필요하십니까? RegistrationsRoutes 클래스마샬링 중에 org.bson.types.ObjectId를 String으로 변환하는 방법은 무엇입니까?
val route: Route = {
withService("registrations") { service =>
import model.RegistrationJsonProtocol._
postRegistration {
entity(as[Registration]) { registration =>
val future = (service ? PostRegistrationMessage(registration)).mapTo[Registration]
onComplete(future) {
case Success(result) =>
log.debug(s"result: ${result}")
complete(result)
case Failure(e) =>
log.error(s"Error: ${e.toString}")
complete(StatusCodes.InternalServerError, Message(ApiMessages.UnknownException))
}
}
}
}
}
