From 4629a2842865565f9b8673beff22030b81ae6220 Mon Sep 17 00:00:00 2001 From: "ian.zhang" Date: Fri, 11 Sep 2020 11:58:21 +0800 Subject: [PATCH] Fix the contentType issue Raise the PR to fix the sample issue by incorrect content type. By given sample, we will get a xls type excel even set excelType(ExcelTypeEnum.XLSX), which will open with an alert even the file encoding is based on xlsx. "The file format and extension of 'xxx' don't match. The file could be corrupted of unsafe. Unless you trust its source, don't open it. Do you want to open it anyway?" The root cause is from incorrect content type. it will be fine if set the content type based on xlsx as below response.setContentType("vnd.openxmlformats-officedocument.spreadsheetml.sheet") Reference: https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types .xls Microsoft Excel application/vnd.ms-excel .xlsx Microsoft Excel (OpenXML) application/vnd.openxmlformats-officedocument.spreadsheetml.sheet --- README.md | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/README.md b/README.md index 9a44127b..1bd0b68d 100644 --- a/README.md +++ b/README.md @@ -80,12 +80,12 @@ DEMO代码地址：[https://github.com/alibaba/easyexcel/blob/master/src/test/ja @GetMapping("download") public void download(HttpServletResponse response) throws IOException { // 这里注意 有同学反应使用swagger 会导致各种问题，请直接用浏览器或者用postman - response.setContentType("application/vnd.ms-excel"); + response.setContentType("vnd.openxmlformats-officedocument.spreadsheetml.sheet"); response.setCharacterEncoding("utf-8"); // 这里URLEncoder.encode可以防止中文乱码 当然和easyexcel没有关系 String fileName = URLEncoder.encode("测试", "UTF-8").replaceAll("\\+", "%20"); response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + fileName + ".xlsx"); - EasyExcel.write(response.getOutputStream(), DownloadData.class).sheet("模板").doWrite(data()); + EasyExcel.write(response.getOutputStream(), DownloadData.class).excelType(ExcelTypeEnum.XLSX).sheet("模板").doWrite(data()); } /**
