java ArrayList HashMap를 Json으로

공통 모듈화 해본 부분
public static JSONObject hashMapJson (ArrayList<HashMap<String, String>> mapList ){
JSONObject data = new JSONObject();
JSONArray req_array = new JSONArray();
JSONObject jsonObject = new JSONObject();

        if(mapList.size() >0){
        for (int i=0; i<mapList.size(); i++) {
        data = new JSONObject();
        for(String key: mapList.get(i).keySet()){
String sValue  = "";
sValue = mapList.get(i).get(key);
        data.put(key, sValue);
        }
        req_array.add(data);
        }
        jsonObject.put("list", req_array);
        }
        return jsonObject;
}

호출해서 사용해보는 부분
@RequestMapping(value = "/xmlFormJson", method = RequestMethod.POST)
public JSONObject xmlFormJson (HttpServletRequest request) {
ArrayList <HashMap<String,String>> mapList = new ArrayList<HashMap<String,String>>();
            // xml 파싱하기 요청하기
        String result = "<?xml version='1.0' encoding='UTF-8' standalone='no'?>"+
