Gson calls returns empty objects over multiple classes

Question

I\'m trying to serialize to serialize the json string I have included below.

 {
        \"mood\": {
            \"is_featured\": true,
            \"de         


        

Answer 1

Root JSON object you provided has property mood - so you either have two options for deserialization to work properly:

1. Wrap your Mood class inside another object like this:

   public class MoodWrapper { private Mood mood; }

   and change de-serialization code to

   MoodWrapper moodWrapper = new Gson().fromJson(result, MoodWrapper.class);

2. Skip a root object when deserializing:

   final Gson gson = new Gson();
   JsonParser parser = new JsonParser();
   JsonObject rootObj = parser.parse(json).getAsJsonObject();
   Mood mood = gson.fromJson(rootObj.getAsJsonObject("mood"), Mood.class);
   

Answer 2

The top-level elements in the JSON string should be your object's properties, not the outer element "mood" which you have.
