用JSONObject取出data【net.sf.json.JSONException: JSONObject["DATA"] is not a JSONArray.】

1、單個取出

　　user.getString("identityCard")

2、取出對象

String userId = getUserId(request);
 JSONObject user = findByPCAndUserVo(userId, config.getHttpsUrlUserAuth(), 1, request);
 String deptName = "";
 String companyName = "";
 if (user.containsKey("departmentVos")) {//一定要記住判斷此對象是否存在
     JSONArray data = user.getJSONArray("departmentVos");
     for (int i = 0; i < data.size(); i++) {
         deptName = data.getJSONObject(i).getString("deptName");
         companyName = data.getJSONObject(i).getString("companyName");
     }
 }
 requestVo.setDeptName(deptName);
 requestVo.setCompanyName(companyName);
 logger.info("requestVo:" + requestVo + "user :" + user);
