 <% 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。
