 提供部分代码

   String sql="*****"; 
   List list = commonDao.getAllRecord(sql);
   GetProperties gp = new GetProperties("dictionary");
   String spath = ServletActionContext.getServletContext().getRealPath("/")+ gp.getProp("uploadpath");
   String name = "planbuycar"+ StrUtil.dateFormatstr(new Date(), "yyyyMMddHHmmss")+ ".csv";
   if (CsvPlanBuyCarFile(spath + name, list)) {
    message = "导出成功";
   } else {
    message = "导出失败";
   }
         

         private static String userxlsinfo = "序号,用户ID,姓名,手机,留言信息,注册时间,";

	public static boolean CsvPlanBuyCarFile(String path, List body) {
