生成Excle模板，SXSSFWorkbook-2007之后版本不上传服务器

Posted 2021-01-30 才小有

@GetMapping("/downTemplateExcel")
    public void downTemplateExcel(HttpServletResponse response) throws IOException {
        SXSSFWorkbook workbook = new SXSSFWorkbook();
        SXSSFSheet sheet = workbook.createSheet("sheet");
        /**
         * 具体导出名字再议
         *
         * ！！！！！！
         */
        String fileName = "test" + ".xlsx";
        int rowNum = 1;
        String[] headers = { "合作商ID", "合作商名称", "类型", "官网"};
        SXSSFRow row = sheet.createRow(0);
        for(int i=0;i<headers.length;i++){
            SXSSFCell cell = row.createCell(i);
            XSSFRichTextString text = new XSSFRichTextString(headers[i]);
            cell.setCellValue(text);
        }
        SXSSFRow row1 = sheet.createRow(rowNum);
        row1.createCell(0).setCellValue("");
        row1.createCell(1).setCellValue("");
        row1.createCell(2).setCellValue("");
        row1.createCell(3).setCellValue("");

        response.setContentType("application/octet-stream");
        response.setHeader("Content-disposition", "attachment;filename=" + fileName);
        response.setCharacterEncoding("utf-8");
        response.setContentType("application/x-download");

        response.flushBuffer();
        workbook.write(response.getOutputStream());
    }

如题，返回的是个url直接前端href即可。

基本参考的就是下面的例子，只不过把版本从2003升级到了2007excle，谢谢。
