Я использую Java и Akka для разработки нового приложения дома, но я сталкиваюсь с проблемами вставки ответа API от Zomato.

Ответ JSON можно найти ниже.Я создал Class Restaurant со списком объектов Restaurant.Как мне разобрать это?

Если json точно такой же, как вы вставили здесь, похоже, что это не правильный json.Попробуйте с этим: 

  {
    "results_found": 131,
    "results_start": 0,
    "results_shown": 10,
    "restaurants": [{
        "restaurant": {

Первое, что есть the JSON is invalid.Я предполагаю, что вы можете управлять действительным JSON.После проверки JSON.

Сначала создайте класс POJO для ресторана.

Свойства для класса Ресторан: 

R: obj
apikey: string
location: obj
.... like .....

добавить все необходимые поля.

После этого используйте код для анализа.но сначала, извлеките рестораны array из JSON. 

gson.fromJson(restaurants, Restaurant[].class);
...
