jsp發請求
<script> <%-- 請求所有導師信息--%> $(function () { $.ajax({ url: "/showTutorsListServlet", type: "post", success: function (jsonArray) { var jsonObj = eval(jsonArray);//json字符串轉為數組 console.log(jsonObj); showData(jsonObj); }, error: function (msg) { alert("ajax連接異常：" + msg); } }); }); </script>

從后端得到JSON字符串數據
-
方一：可以創建相應實體，list轉為JSON對象
List<Tutor> tutorList = showTutorsListService.getTutorsByDepart(depart); //將list轉換成json對象 JSONArray jsonArray = JSONArray.fromObject(tutorList); //發送數據 resp.getWriter().write(jsonArray.toString()); -
方二：沒有相應實體，也可以直接將字符串拼成JSON數組字符串，像下面那樣。
-
（下面是JSON數組字符串 拼接后的結果）
[ {"specialty":"軟件工程","sex":false,"tutorNo":"20170000","degree":"博士","birth":"2020-06-18","password":"20170000","tutorName":"root","post":"博士","phone":"155","quota":4,"surplusQuota":3,"researchField":"人工智能","depart":"計算機科學與技術學院","email":"124"} ,{"specialty":"計算機","sex":false,"tutorNo":"20170001","degree":"博士","birth":"2020-06-20","password":"20170001","tutorName":"root2","post":"博士","phone":"155","quota":4,"surplusQuota":4,"researchField":"人工智能","depart":"計算機科學與技術學院","email":"124"} ] -
