android– 没有创建者,比如默认构造,存在):无法从Object值反序列化(没有基于委托或属性的Creator,第1张

概述我正在尝试使用改造和杰克逊来消费API以进行反序列化.标题“NoCreators,如默认构造,存在”中出现的错误:无法从Object值反序列化(onFailure中不会出现基于委托属性的Creator“).这是我想要获取的JSON:{"data":{"repsol_id":"1129","name":"ES-MASSAM

我正在尝试使用改造和杰克逊来消费API以进行反序列化.标题“No Creators,如默认构造,存在”中出现的错误:无法从Object值反序列化(onFailure中不会出现基于委托或属性的Creator“).

这是我想要获取的JSON:

{    "data": {        "repsol_ID": "1129",        "name": "ES-MASSAMÁ",        "latitude": "38.763733333",        "longitude": "-9.258619444000001",        "address": "RUA GENERAL HUMBERTO DELGADO, LT.16",        "post_code": "2745-280",        "location": "QUELUZ",        "service_store": 1,        "service_mechanical_workshop": 0,        "service_restaurant": 0,        "service_wash": 1    }}

这是我的HomeFragment:

onCreate(){ viewmodel.retrIEveStation().observe(this, Observer {            dataBinding.favouriteStationTxt.text = it.name        })}

这是我的viewmodel:

class Homeviewmodel @Inject constructor(        private val stationRepository: StationRepository) : viewmodel() {    private val station = mutablelivedata<Station>()    fun retrIEveStation():liveData<Station> = station    fun loadStations(stationID:Int){        stationRepository.getStationFromID(stationID,{ station.postValue(it)},{})    }}

这是我的存储库:

class StationRepository @Inject constructor(var apimanager: apimanager) {    fun getStationFromID(stationID:Int,onSuccess: (Station)->Unit, one rror: (Exception)->Unit){        apimanager.getStation(stationID, onSuccess,onError)    }}

这是我的API管理器(加入了几个API管理器)

class apimanager @Inject constructor(        private val stationsapimanager: Stationsapimanager, ){ fun getStation(stationID: Int, onSuccess: (Station)->Unit, onFailure: (e: Exception)->Unit){        stationsapimanager.getStation(stationID,{onSuccess(it.data.todomain())},onFailure)    }}

这是我的Stationapimanager

class Stationsapimanager  @Inject constructor(private val stationAPIService: StationsAPIService){ fun getStation(stationID: Int, onSuccess: (StationResponse)->Unit, onFailure: (e: Exception)->Unit){        stationAPIService.getStation(stationID).enqueue(request(onSuccess, onFailure))    } private fun <T> request(onSuccess: (T)->Unit, onFailure: (e: Exception)->Unit)= object : Callback<T> {        overrIDe fun onFailure(call: Call<T>, t: Throwable) {            Log.d("error",t.message)            onFailure(Exception(t.message))        }        overrIDe fun onResponse(call: Call<T>, response: Response<T>) {            Log.d("Success",response.body().toString())            if(response.isSuccessful && response.body() != null) onSuccess(response.body()!!)            else                onFailure(Exception(response.message()))        }    }}

这是我的STationsAPIService(基本URL在风格中)

@GET("{station_ID}")    fun getStation(@Path("station_ID") stationID: Int): Call<StationResponse>

这是我的StationResponse

class StationResponse (        @JsonProperty("data")        val data: Station)

这是我的车站模型

data class Station(        val repsol_ID: String,        val name: String,        val latitude: String,        val longitude: String,        val address: String,        val post_code: String,        val location: String,        val service_store: Boolean,        val service_mechanical_workshop: Boolean,        val service_restaurant: Boolean,        val service_wash: Boolean)

这是我的DataMappers:

import com.repsol.repsolmove.network.movestationsAPI.model.Station as APIStationfun APIStation.todomain() = Station(        repsol_ID.toInt(),        name,        latitude.todouble(),        longitude.todouble(),        address,        post_code,        location,        service_store,        service_mechanical_workshop,        service_restaurant,        service_wash)

解决方法:

试试以下型号.我使用http://www.jsonschema2pojo.org/来创建这些模型.
