使用JAVA API上传文件到FTP服务器

 private void FtpUpload() throws IOException {
  String ftpServer = "ftp server ip address";
  String username = "username";
  String password = "password";
  String filename = "filename";
  String path = "/path";
  FtpClient ftpClient = new FtpClient();
  ftpClient.openServer(ftpServer);
  ftpClient.login(username, password);
  ftpClient.binary();
  TelnetOutputStream os = ftpClient.put(filename);// 服务器上保存的文件名
  InputStream is = new FileInputStream("/path");// 本地文件路径
  byte[] bytes = new byte[1048576];
  int c;
  while ((c = is.read(bytes)) != -1) {
   os.write(bytes, 0, c);
  }
  os.close();
  ftpClient.closeServer();
 }
