Return key value of a JSON request in Spring

I'm trying to create a route to perform a GET Request to /winner to show the restaurants that had the count of 3 votes in the JSON, but every time I do the GET, it returns the value of null instead of the value I would like.
I was expecting something like that:
{
"id": 1,
"restaurant": "Burger King",
"address": "Av. Ipiranga, 1600",
"website": "https://www.burgerking.com.br/",
"description": "Rede de fast-food famosa com hambúrgueres grelhados, batata frita e milk-shakes.",
"count": 3
}
Instead that, I'm just getting an empty JSON with the null value.
Here are the classes I'm using:

}

you didn't access dao in the method findWinner.
restaurants instance has just created without accessing dao.
#Transactional(readOnly = true)
public Restaurant findWinner(Integer count) {
List<Restaurant> restaurants = new ArrayList<>();
for (Restaurant restaurant: restaurants) {
if(restaurant.getCount().equals(3)) {
return restaurant;
}
}
return null;
}

because in the find winner method you have initialized restaurants with an empty array list.
It should be like this.
#Transactional(readOnly = true)
public Restaurant findWinner(Integer count) {
List<Restaurant> restaurants = repository.findAll();
for (Restaurant restaurant: restaurants) {
if(restaurant.getCount().equals(3)) {
return restaurant;
}
}
return null;
}

and im trying to getID and use that in another call. This is an object that I am trying to turn into an integer an then use that in a seperate call again.
referralResponseResponse = call1.getReferral(token).execute();
int i = (int) referralResponseResponse.body().getId();
System.out.println("Int: " + i);
I should also note the json that I'm using this data from is very large so ive just used jsonpogo to extract this information to a java file and then use the parts that apply to me, I dont imagine i have to set up a java class for every part of the retruned json

Try to add following annotation for your POJO class:
#JsonIgnoreProperties(ignoreUnknown = true)

If you are just trying to the the name from camera_type and dvr_type, you can do:
//This assumes that you have a getCameraType & getDvrTypes method in your OrderDetailsGet class
String camera_name = orderDetails.getData().get(0).getCameraType().getName()
String dvr_name = orderDetails.getData().get(0).getDvrTypes().getName()

List<PaymentDetail> data = new ArrayList<PaymentDetail>();
PaymentDetail paymentDetail = new PaymentDetail();
paymentDetail.setAmount("999.00");
data.add(paymentDetail);
JSONObject jsonObject = new JSONObject(example);
JSONArray jsonArray = new JSONArray(data);
jsonArray.put(data);
System.out.println(jsonArray.put(data));
}

In your test class, what you must do is separate the test data creation to a different class and pass that as data provider to your test method. This is from design point of view.
Coming to your problem:
You are already using gson, why are you constructing a JSONObject. Instead do something like below;
Gson gson = new Gson();
String _my_obj = gson.toJson(example);
Hope this is what you are looking for.

I have looked into the below posts in order to avoid duplicate question
JAXB unmarshal returning null values
JAXB unmarshalling returning Null

There are many mismatch between your provided XML and JAXB class.
Firstly, there are no attributes in your sample XML, but the JAXB contains #XmlAttribute.
Secondly, it is better to declare the #XmlAccessorType explicitly or otherwise it looks for only public fields and methods.
