UnrecognizedPropertyException: Unbekanntes Feld „Code“ in Android

Question

ich durch einen Wert von Jsonutil Code zurückkehren möchten, mit ObjectMapper aber Daten nicht reflektieren

I Modell verwende, von dem ich ein decription Wert reflektieren und in Spinner hinzufügen möchten

ich habe diesen Fehler:

Mein Java-Code wird verwendet, Spinner Daten zu erhalten:

try{ 
      JSONObject msgJSON = new JSONObject(); 
      msgJSON.put("objName", "LKClass"); 
      SharedPreferences sharedPref = context.getSharedPreferences 
        (ApplicationUtils.SHARED_PREFERENCES_NAME, Context.MODE_PRIVATE); 
      if (ApplicationUtils.BASE_URL == null) { 
       String response = VEMSServices.getInstance(context).getResponseData(msgJSON.toString(), ApplicationUtils.GET_OBJECT); 
       JSONArray jsonArray = new JSONArray(response); 
       final ArrayList<LKClassData> spn = new ArrayList<>(); 
       for (int i = 0; i < jsonArray.length(); i++) { 
        spn.add((LKClassData) JSonUtil.jsonToObject(jsonArray.getString(i), LKClassData.class)); 

        Log.v("Check Value",spn.toString()); 
        //JSONObject jsonObject = jsonArray.getJSONObject(i); 
        //spn.add(new LKClassData(jsonObject.getString("description"), jsonObject.getString("primaryKey"))); 
       } 
       vSpinner = new VisioneeringSpinner(context); 
       vSpinner.getSpinner(R.id.spinner_stu_Attendance_Class, spn, this.getActivity()); 

Mein JsonUtil Klassencode ist:

public static Object jsonToObject(String jsonData, Class<?> clazz) { 
     Log.v("Util Data",jsonData); 
     try { 
      return mapperObj.readValue(jsonData, clazz); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

My Model-Klasse Daten:

public class LKClassData { 


    public String description; 
    public String primaryKey; 

    @Override 
    public String toString() { 
     return description; 
    } 
} 

Answer 1

Try @JsonIgnoreProperties(ignoreUnknown = true) der Klasse Hinzufügen LKClassData

@JsonIgnoreProperties(ignoreUnknown = true) 
public class LKClassData { 

    public String description; 
    public String primaryKey; 

    @Override 
    public String toString() { 
     return description; 
    } 
}
