填充模板下载excel，后缀是xls，提示：excel无法打开文件，文件格式或扩展名无效

[zJohny]

异常代码

private static void extracted(HttpServletResponse response,List<HashMap<String, Long>> maps) throws FileNotFoundException {
InputStream resourceAsStream = GpCellsController.class.getResourceAsStream("/fill/exceltemplate/模板.xls");
if (resourceAsStream == null) {
throw new FileNotFoundException("未找到模板文件");
}
try(ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream()).withTemplate(resourceAsStream).excelType(ExcelTypeEnum.XLS).build()){
if(maps!=null){
maps.forEach(map->{
WriteSheet writeSheet1 = EasyExcel.writerSheet("月报表").build();
excelWriter.fill(map, writeSheet1);
});
}
String fileNamedownload = "详细信息" + System.currentTimeMillis()+".xls";
log.info("生成的报表名：{}",fileNamedownload);
response.setContentType("application/vnd.ms-excel");
response.setCharacterEncoding("utf-8");
String fileName1= URLEncoder.encode(fileNamedownload,"UTF-8").replaceAll("\+","%20");
response.setHeader("Content-disposition","attachment;filename*=utf-8''"+fileName1);
excelWriter.finish();
} catch (IOException e) {
throw new RuntimeException(e);
}

异常提示

代码无报错，本地测试无误，部署到Linux上就会出现扩展名无效的现象，而且我设置的后缀是.xls，下载下来就变成.xlsx

问题描述

下载下来之后，文件名也不正常，应该是“负债表1732104616044.xls”，而实际上是“负债表.xls”，时间戳也没有了

问题已解决，不是easy excel的问题，是我们前端把文件流重新命名了。
