通過IO流下載Excel文件

1、后台將文件通過輸出流輸出到前端

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、前端頁面接收輸出流，直接請求該接口即可，或者window.location.href= ' 接口 '
