一层结构的数据：
{ "code": "0", "results": { "boyTotal": 0, "classNumber": 0, "enrollmentsTotal": 0, "girlTotal": 0, "mobile": "15969538305", "studentTotal": 0, "userCode": "141920370", "userName": "杜文兵", "userType": "1" }} 二层结构的数据：

先上代码：
JSONObject obj1 = new JSONObject(); obj1.put("mobile", "13008662173"); //查询员工编号 JSONObject userInfo = ToolsWebReq.sendPost(ToolsWebReq.TEACHER_SERVER_BASE_URL + ToolsWebReq.API_QUERYUSERID,obj1); List userInfos = (List ) JsonUtils.JsonToList(userInfo.get("results"), new UserInfo()); String userCode = ""; if(userInfos != null ){ for (int i = 0; i < userInfos.size(); i++) { UserInfo user = userInfos.get(i); userCode = user.getUserCode(); } } System.out.println("userCode="+userCode); //通过员工编号查询班级数 List list2 = null; JSONObject obj = new JSONObject(); obj.put("userCode", "131530220"); JSONObject classList = ToolsWebReq.sendPost(ToolsWebReq.TEACHER_SERVER_BASE_URL + ToolsWebReq.API_QUERYCLASSNUM,obj); //解析第一层 JSONObject rs = (JSONObject) classList.get("results"); //解析第二层 JSONArray arrayList = (JSONArray) rs.get("arrayList"); List classLists = (List ) JsonUtils.JsonToList(rs.get("arrayList"), new UserClassInfo()); System.out.println("classLists.get(0).getClassName()="+classLists.get(0).getClassName()); 方法：
