Jsch 在尝试连接到 AWS Transfer 系列下的 SFTP 服务器时断开连接

问题描述 投票：0回答：1

我正在尝试使用 Jsch 连接到 SFTP 服务器。我的代码如下所示

public void putFile(
      final SftpConfig sftpConfig, final InputStream inputStream, final String remoteFileName) {
    Session sftpSession = null;
    Channel sftpChannel = null;
    try {
      JSch.setLogger(new MyLogger());
      val sftpShell = new JSch();
      if (sftpConfig.hasSecretKey()) {
        sftpShell.addIdentity(
            "dev03sftp.pem", getPassword(sftpConfig.getSecretKey()).getBytes(), null, null);
      }

      sftpSession =
          sftpShell.getSession(
              sftpConfig.getUsernamePassword().getUsername(),
              sftpConfig.getRemoteHost(),
              sftpConfig.getRemotePort());

      if (sftpConfig.hasUsernamePassword()) {
        sftpSession.setPassword(getPassword(sftpConfig.getUsernamePassword()));
      }
      
      sftpSession.setConfig("StrictHostKeyChecking", "no");
      sftpSession.setConfig("PreferredAuthentications", "publickey,keyboard-interactive,password");

      sftpSession.connect();
      sftpChannel = sftpSession.openChannel("sftp");
      sftpChannel.connect();

      log.info("sftp session connected");
      putFileInternal(sftpConfig, (ChannelSftp) sftpChannel, inputStream, remoteFileName);
    } catch (final JSchException jSchException) {
      throw ExceptionUtils.internalErrorException(
          CommonError.CONNECTION_ERROR, "Error in establishing sftp session", jSchException);
    } catch (SftpException sftpException) {
      throw ExceptionUtils.internalErrorException(
          CommonError.CONNECTION_ERROR, "Error in putting file via sftp session", sftpException);
    } finally {
      if (sftpChannel != null && sftpChannel.isConnected()) {
        sftpChannel.disconnect();
      }
      if (sftpSession != null && sftpSession.isConnected()) {
        sftpSession.disconnect();
      }
    }
  }

我从 

sftpSession.connect();
收到以下错误。

我在服务器端没有看到任何错误。

我可以使用 Mac SFTP 客户端连接到 SFTP 服务器。只有 Jsch 才会失败。

我将私钥从 Openssh 更改为 RSA，并且成功了。

完整的工作代码

public void putFile(
      final SftpConfig sftpConfig, final InputStream inputStream, final String remoteFileName) {
    Session sftpSession = null;
    Channel sftpChannel = null;
    try {
      // JSch.setLogger(new MyLogger());
      val sftpShell = new JSch();
      if (sftpConfig.hasSecretKey()) {
        sftpShell.addIdentity(
            "key.pem", getPassword(sftpConfig.getSecretKey()).getBytes(), null, null);
        sftpSession =
            sftpShell.getSession(
                sftpConfig.getSecretKey().getUsername(),
                sftpConfig.getRemoteHost(),
                sftpConfig.getRemotePort());
      } else {
        sftpSession =
            sftpShell.getSession(
                sftpConfig.getUsernamePassword().getUsername(),
                sftpConfig.getRemoteHost(),
                sftpConfig.getRemotePort());
        sftpSession.setPassword(getPassword(sftpConfig.getUsernamePassword()));
      }

      // NB: Turn off host verification since the key is calculated on a per-client basis and will
      // be different for each env.
      sftpSession.setConfig("StrictHostKeyChecking", "no");
      sftpSession.connect();
      sftpChannel = sftpSession.openChannel("sftp");
      sftpChannel.connect();

      log.info("sftp session connected");
      putFileInternal(sftpConfig, (ChannelSftp) sftpChannel, inputStream, remoteFileName);
    } catch (final JSchException jSchException) {
      throw ExceptionUtils.internalErrorException(
          CommonError.CONNECTION_ERROR, "Error in establishing sftp session", jSchException);
    } catch (SftpException sftpException) {
      throw ExceptionUtils.internalErrorException(
          CommonError.CONNECTION_ERROR, "Error in putting file via sftp session", sftpException);
    } finally {
      if (sftpChannel != null && sftpChannel.isConnected()) {
        sftpChannel.disconnect();
      }
      if (sftpSession != null && sftpSession.isConnected()) {
        sftpSession.disconnect();
      }
    }
  }

SFTP 客户端可以同时使用两者。
