把文件流写入HttpServletResponse

[五味子1314]

用httpserveltresponse获取writeout输出流，把读到的文件流放到这个输出流中

下载什么文件？bufferreader是字符流 String downFilename=request.getParameter("curfile"); String filepath=request.getParameter("path"); response.setContentType("text/plain"); response.setHeader("Location",downFilename); response.setHeader("Content-Disposition", "attachment; filename=" + downFilename); OutputStream outputStream = response.getOutputStream(); InputStream inputStream = new FileInputStream(filepath+downFilename); byte[] buffer = new byte[1024]; int i = -1; while ((i = inputStream.read(buffer)) != -1) { outputStream.write(buffer, 0, i); } outputStream.flush(); outputStream.close();
