java调用webservice(并不是以.wsdl结尾的)并对返回的jason数据进行解释

1、返回的jason格式为：

{
  "iChatAccountList": [
    {
      "acctNo": "string",
      "acctStat": "string",
      "contNo": "string",
      "contStat": "string",
      "contractEndDate": "string",
      "custName": "string",
      "servDescChi": "string",
      "servDescEn": "string",
      "servType": "string",
      "subNo": "string",
      "totalAmntDue": "string"
    }
  ],
  "success": true
}

2、通过HttpURLConnection拿到webservice返回的jason数据，对其进行解释并存放在一个javabean中

public List getLoginMessage(String custId, String custName) {
		String strMessage = "";
		String servType, acctNo, contNo, acctStat, contStat, subNo, contractEndDate, totalAmntDue, custName1,
				servDescEn, servDescChi;
		HttpURLConnection conn = null;
		List resultList = new ArrayList();

		try {
			JSONObject jsonObject = new JSONObject();
			jsonObject.put("custId", custId);
			jsonObject.put("custName", custName);

			URL restUrl = new URL("http://192.168.44.24:9001/crmWS/fixedIChatLogin/login");
			conn = (HttpURLConnection) restUrl.openConnection();
			conn.setRequestMethod("POST");
			conn.setRequestProperty("Accept", "application/json");
			conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");

			conn.setDoInput(true);
			conn.setDoOutput(true);
			DataOutputStream dos = new DataOutputStream(conn.getOutputStream());
			dos.writeBytes(jsonObject.toString());
			log.info("jsonobject:" + jsonObject.toString());
			dos.flush();
			dos.close();

			int responseCode = conn.getResponseCode();
			log.info("getLoginMessage responseCode=" + responseCode);
			if (responseCode == 200) {
				BufferedReader bReader = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
				String strOutPut = "";
				StringBuilder sBuilder = new StringBuilder();

				while ((strOutPut = bReader.readLine()) != null) {
					sBuilder.append(strOutPut);
				}

				JSONObject jObject = new JSONObject(sBuilder.toString());
				String sign = jObject.getString("success");
				log.info("whether the login is successful-----" + "--sign:" + sign);

				JSONArray jArr = jObject.getJSONArray("iChatAccountList");

				for (int i = 0; i < jArr.length(); i++) {
					loginMessage lm = new loginMessage();
					JSONObject obj2 = jArr.getJSONObject(i);
					servType = obj2.getString("servType");
					acctNo = obj2.getString("acctNo");
					contNo = obj2.getString("contNo");
					acctStat = obj2.getString("acctStat");
					contStat = obj2.getString("contStat");
					subNo = obj2.getString("subNo");
					contractEndDate = obj2.getString("contractEndDate");
					totalAmntDue = obj2.getString("totalAmntDue");
					custName1 = obj2.getString("custName");
					servDescChi = obj2.getString("servDescChi");
					System.out.print(servDescChi + "+++++++++++++++++++++++++++++++++");
					servDescEn = obj2.getString("servDescEn");
					lm.setSign(sign);
					lm.setServType(servType);
					lm.setAcctNo(acctNo);
					lm.setContNo(contNo);
					lm.setAcctStat(acctStat);
					lm.setContStat(contStat);
					lm.setSubNo(subNo);
					lm.setContractEndDate(contractEndDate);
					lm.setTotalAmntDue(totalAmntDue);
					lm.setCustName(custName1);
					lm.setServDescChi(servDescChi);
					lm.setServDescEn(servDescEn);
					resultList.add(lm);
				}

			} else {
				log.info("Loing failed");
				loginMessage lm = new loginMessage();
				lm.setSign("false");
				resultList.add(lm);
				return resultList;

			}

		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {

			e.printStackTrace();

		} catch (Exception ex) {
			ex.printStackTrace();
		} finally {

			if (conn != null) {
				conn.disconnect();
			}
		}
		return resultList;
