class ContentDeserializer implements JsonDeserializer {
    @Override
    public Content deserialize(JsonElement je, Type type, JsonDeserializationContext jdc)
        throws JsonParseException {
        // Extract the "content" element
        JsonElement content = je.getAsJsonObject().get("content");

        // Deserialize the content using a new Gson instance
        return new Gson().fromJson(content, Content.class);
    }
}

تكوين Gson:

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

التكامل التحديثي:

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