如何使用 Ajax 将 Array 值从 Javascript 格式化为 Java Servlet

Question

我需要你的帮助。我使用 AJAX 将这个数组从 Javascript 传递到 Java Servlet。Javascript 和 AJAX 片段代码：var BuildingNo = [];$(xml).find('BUILDING').each(function(){    BuildingNo.push($.trim(this).children('BuildingNo').text());}传递给 Java Servlet 之前的 BuildingNo 值。alert(BuildingNo);// 00101,00102,00103,00104,00105 当我通过 Ajax 将 BuildingNo 传递给 Java Servlet 时 JSON.stringify(BuildingNo) 的值。data: { BuildingNo : JSON.stringify(BuildingNo) },alert(JSON.stringify(BuildingNo));// ["00101","00102","00103","00104","00105"] 这是我用来将 BuildingNo 传递给 oldBuilding 列表的 Java Servlet 片段代码。protected void doGet(HttpServletRequest request, HttpServletResponse response) throws (ServletException, IOException {List <String> oldBuildingList = Arrays.asList(request.getParameter("BuildingNo");logger.info(oldBuildingList);// [["00101","00102","00103","00104","00105"]] -- This is a wrong format.//I have a Java code here which captures a new list of BuildingNo from another service.List <String> newBuildingList = new ArrayList <String>();logger.info(newBuildingList.toString());// [00106,00107,00108,00109,00110] -- This should be the correct format of oldBuildingList.}如何使用 oldBuildingList 获得相同格式的 newBuildingList？

不要字符串化只是保持原样 data: { BuildingNo : BuildingNo }

在 Java Servlet 中 List <String> oldBuildingList = Arrays.asList(request.getParameterValues("BuildingNo[]");
