Answer 1

如果到www.javawebstudio.com提问将得到更快的回答。试把代码改成：FormFile file = myform.getTheFile();                 
                       InputStream stream = file.getInputStream();
                       String filename=getServlet().getServletContext().getRealPath("/")+file.getFileName();
                       OutputStream bos = new FileOutputStream(filename);
                       int bytesRead = 0;
                       byte[] buffer = new byte[8192];
                       
                       while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
                           bos.write(buffer, 0, bytesRead);
                       }
                       bos.close();
