Question

im尝试使用Java jsch lib将大文件（2.5GB）上传到sftp服务器。在短暂的异常后，用stacktrace抛出：

这是我的代码：

    val jsch =  new JSch
val session = jsch.getSession("user", "host", 8442)
session.setConfig("StrictHostKeyChecking", "no")
session.setTimeout(60000)
session.setServerAliveInterval(3000)

try {
  session.setPassword("pass")
  session.connect()
  val channel = session.openChannel("sftp")
  channel.connect()
  val sftpChannel = channel.asInstanceOf[ChannelSftp]
  if (!sftpChannel.isConnected) println("Failed to open connection to SFTP")
  sftpChannel.cd("folder/folder2")
  val f = new File(file)

  sftpChannel.put(new FileInputStream(f),f.getName)
  sftpChannel.exit()
} finally if (session != null) if (session.isConnected) session.disconnect()

请注意，从命令行（ubuntu）使用sftp客户端上载相同的文件时，文件已使用相同的用户名/密码和服务器成功上载。该代码也适用于较小的文件。

我需要为大文件进行设置吗？

使用jsch将大文件上传到sftp服务器失败，并出现java.net.SocketException：短时间内连接重置异常
