 <%			String ExcelName = "核验列表.xlsx";

    		ExcelName=new String(ExcelName.getBytes("GB2312"), "ISO_8859_1");//解决文件名为中文时文件错误的问题

            response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");

            response.setHeader("Content-Disposition", "inline; filename="

                    + ExcelName);

    %>

</html>

打开当前页面就会导出excel，报错信息如下图

如果导出xls格式是没有问题，header和ContentType这么写的话：
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "inline; filename="
+ ExcelName+".xls");
但是现在要求导出xlsx格式，求助大佬们，帮看看。
