OutputStream out = response.getOutputStream();
response.addHeader("content-type", "application/shlnd.ms-excel;charset=utf-8");
response.addHeader("content-disposition", "attachment; filename='设备列表'" + Times.sDT(new Date()) + "我.xls");
J4E.toExcel(out, deviceVoList, j4eConf);
这样只是日期作为名称, ' '2019-03-11 16_52_28 .xls 好奇怪
