通过IO流下载Excel文件

1、后台将文件通过输出流输出到前端

InputStream inputStream = this.getClass().getResourceAsStream("/template/XXX模板.xlsx"); Workbook workbook = new XSSFWorkbook(inputStream); if (workbook!=null) { String fileName = "XXX模板.xlsx"; String headStr = "attachment;fileName=\""+new String(fileName.getBytes("UTF-8"), "iso8859-1")+"\""; response.setContentType("application/octet-stream"); response.setHeader("Content-Disposition", headStr); OutputStream outputStream = response.getOutputStream(); workbook.write(outputStream); }

2、前端页面接收输出流，直接请求该接口即可，或者window.location.href= ' 接口 '
