其中：
String accountDate 入參（日期）AccountInfoEntityResp accountInfoEntityResp 匯出的xml報文內容（轉換成obj物件）xml報文解析見另一篇：xml報文解析
HttpServletRequest request
HttpServletResponse response 主要核心程式碼如下：
/** * 匯出exc方法 */ public void exportExcel(String accountDate, AccountInfoEntityResp accountInfoEntityResp,HttpServletRequest request,HttpServletResponse response) throws IOException { // 宣告一個工作簿 HSSFWorkbook wb = new HSSFWorkbook();
