尝试在将kotlin数据类作为文档保存到Google Cloud Firestore时排除字段

我有这个数据类

data class TripEntity(@Exclude val id: String = "", val name: String = "", val totalDistance: Long = 0, val startDate: Date?, val endDate: Date?) 

然后我有这些方法来坚持数据

 private fun writeNewTripEntity(tripEntity: TripEntity, emitter: ObservableEmitter) { val tripCollection = FirebaseFirestore.getInstance().collection("users/test/trips"); tripCollection.add(tripEntity).addOnSuccessListener({ documentReference -> onWriteEntitySuccess(documentReference, emitter, tripEntity) }).addOnFailureListener({ e -> onWriteEntityError(e, emitter) }) } private fun onWriteEntitySuccess(documentReference: DocumentReference, emitter: ObservableEmitter, tripEntity: TripEntity) { Timber.log(Log.DEBUG, "TripEntity saved to FireBase successfully: " + documentReference.toString()) emitter.onNext(TripEntity(documentReference.id, tripEntity.name, tripEntity.totalDistance, tripEntity.startDate, tripEntity.endDate)) emitter.onComplete() } private fun onWriteEntityError(e: Exception, emitter: ObservableEmitter) { Timber.e("Data could not be saved: %s", e.message) emitter.onError(e) } 

然后该文档被保存在Firestore中，但不会排除该ID，因为它应该根据Firestore文档。

谢谢你的帮助。
