Question

I am making a query call to freebase and I receive a JSON response. The response has the following structure:

{
  "code":          "/api/status/ok",
  "result": [
    {
      "/common/topic/image": [{
        "guid": "#9202a8c04000641f8000000004b67f6d"
      }],
      "/people/person/profession": [{
        "name": "Critic"
      }],
      "id":   "/en/michael_jackson_1942",
      "name": "Michael Jackson",
      "type": "/people/person"
    },  
    {
      "/common/topic/image": [{
        "guid": "#9202a8c04000641f800000001b90fdea"
      }],
      "/people/person/profession": [{
        "name": "Actor"
      }],
      "id":   "/en/michael_jackson_1970",
      "name": "Michael Jackson",
      "type": "/people/person"
    }
  ],
  "status":        "200 OK",
  "transaction_id": "cache;cache03.p01.sjc1:8101;2012-01-16T18:28:36Z;0055"
}

I need to parse this response in a ArrayList of java objects using GSON. To do this I need to create the class of the object with get/set and make it available to parse. Or is there another simpler way to do things ? I have used simple JSON strings by now, but in this case I can’t remake the structure of the class I need. Basically in the end I need something like ArrayList<Person> where Person has all the attributes from the json string.

Any help is appreciated. Thank you.

The final solution, according with the answer below

public class FreebaseResponse {
    @SerializedName("code")
    public String code;

    @SerializedName("result")
    public ArrayList<Person> result;

    @SerializedName("status")
    public String status;

    @SerializedName("transaction_id")
    public String transaction_id;
}

public class Person {
    @SerializedName("/common/topic/image")
    public ArrayList<Person.Guid> imageGuid;

    @SerializedName("/people/person/profession")
    public  ArrayList<Person.Profession> profession;

    @SerializedName("id")
    public String id;

    @SerializedName("name")
    public String name;

    @SerializedName("type")
    public String type;

    private class Guid
    {
        @SerializedName("guid")
        public String guid;
    }

    private class Profession
    {
        @SerializedName("name")
        public String name;
    }
}

I guess you can create a FreebaseResponse class that contains code, result (ArrayList<Person>), etc fields and use Gson to deserialize. the names that are not valid identifiers, e.g. /common/topic/image will be a problem. I haven’t tried it myself but it seems to me that SerializedName annotation should do the trick.
