Parse Realm Model Using Jackson

Getting unknown key while converting realm model into json object using jackson library. Here is my realm model instance. public class RecordData extends RealmObject { pu

Solution 1:

Write response from ObjectMapper, you have to do this:

publicstaticStringgetJsonFromObject() {
        ObjectMapper objectMapper = ObjectMapperHelper.getObjectMapperInstance();
        String jsonString = null;
           try {
            jsonString = objectMapper.writeValueAsString(formData.getRecordData());
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
        return jsonString != null ? jsonString : "";
    }

and get your response in JsonObject :

try {
    JSONObject jsonObject = newJSONObject().getJSONObject(getJsonFromObject());
     } catch (JSONException e) {
       e.printStackTrace();
       }

Happy coding!!

Solution 2:

I have solved it using Gson parsing library.

JSONObject recordDataJsonObject = newJSONObject(newGson().toJson(formData.getRecordData()));

Its not return unknown key. Output is here.

{"value":"fdfdf","values":[]}

Hope you will find this solution if you are facing same case.

Solution 3:

You could use @JsonIgnoreProperties annotation:

@JsonIgnoreProperties({"loaded", "managed", "valid"})
public class RecordData extends RealmObject {

    publicRecordData() {

    }

    private FormData formData;

    @Nullable@JsonProperty("values")
    private RealmList<Values> values;

    @Nullable@JsonProperty("value")
    private String value;
}

Another option is to use @RealmClass public class RecordData implements RealmModel.
