Gson 및 Retrofit을 사용하여 API 응답에서 중첩된 JSON 개체를 추출하는 방법은 무엇입니까?

{
  'status': 'OK',
  'reason': 'Everything was fine',
  'content': {
    < real data here >
  }
}

class MyDeserializer implements JsonDeserializer<Content> {
  @Override
  public Content deserialize(JsonElement je, Type type, JsonDeserializationContext jdc) {
    // Get the "content" element from the parsed JSON
    JsonElement content = je.getAsJsonObject().get("content");

    // Deserialize it using a new Gson instance to avoid recursion
    return new Gson().fromJson(content, Content.class);
  }
}

Gson gson = new GsonBuilder()
  .registerTypeAdapter(Content.class, new MyDeserializer())
  .create();

Retrofit retrofit = new Retrofit.Builder()
  .baseUrl(url)
  .addConverterFactory(GsonConverterFactory.create(gson))
  .build();

class MyDeserializer<T> implements JsonDeserializer<T> {
  @Override
  public T deserialize(JsonElement je, Type type, JsonDeserializationContext jdc) {
    // Get the "content" element from the parsed JSON
    JsonElement content = je.getAsJsonObject().get("content");

    // Deserialize it using a new Gson instance to prevent recursion
    return new Gson().fromJson(content, type);
  }
}
