解决办法:在填写文件的路径时一定要具体到文件
源码:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("已经接收到请求"); //从request当中获取流信息 InputStream fileSource = request.getInputStream(); String tempFileName = "D:/tempfile.png"; //tempFile指向临时文件 File tempFile = new File(tempFileName); //outputStream文件输出流指向这个临时文件 FileOutputStream outputStream = new FileOutputStream(tempFile); byte b[] = new byte[1024]; int n; while((n=fileSource.read(b)) != -1){ outputStream.write(b, 0, n); } //关闭输入输出流 outputStream.close(); fileSource.close(); } }
