I am writing Junit test case for my REST service, i am setting the values(below is the piece of code) to get the payload required for REST service

Payload jsonPayload = new Payload ();
payload.setAcc("A");
List<Details> details= new ArrayList<Details>;
Details detail = new Details();
detail.setTotalAmount(1);
detail.setCurrency("dollar");
details.add(detail);
payload.getDetails().addAll(details);

I want JSON to be built in format mentioned below, but I am not getting the JSON as expected, details should be in form of Array.

Required JSON -

   {
  "Acc" : "A",
    "details": [
     { 
      "totalAmount":1,
      "currency":"dollar"
     }
   ]
 }

Output JSON -

 {
 "Acc" : "A",
  "details": 
   { 
     "totalAmount":1,
     "currency":"dollar"
  }
}

Can anyone help me how can I achieve this?

What happens when you add 2 or more details? – yugo Feb 02 '16 at 13:29
Btw, your question summary is misleading. It should point to json format problem – yugo Feb 02 '16 at 13:30

You should also specify which json library you are using – semperfids Feb 02 '16 at 13:31
@Yugo - I am getting proper array in the required format if i pass more than 1 details – Nagendra Feb 02 '16 at 15:13
@semperfids, I am not using any JSON library. I am writing junit test case for REST service and using setters and getters to build JSON data, as REST is not getting the data in required format, it's throwing any error – Nagendra Feb 02 '16 at 15:14
Perhaps the link posted by @Robert would help you though – yugo Feb 02 '16 at 15:15
I tried using JAXBContextResolver, but the request is not going to JAXBContextResolver code – Nagendra Feb 03 '16 at 04:32
JAXBContextResolver is working only for GET methods, not for POST – Nagendra Feb 03 '16 at 06:37
