另一个选择是考虑查看JSch库。JSch似乎是一些大型开源项目的首选库，其中包括Eclipse，Ant和Apache Commons HttpClient。
它很好地支持用户/通过和基于证书的登录，以及所有其他许多美味的SSH2功能。
这是通过SFTP检索的简单远程文件。错误处理留给读者练习：-)
JSch jsch = new JSch();
String kNownHostsFilename = "/home/username/.ssh/kNown_hosts";
jsch.setKNownHosts( kNownHostsFilename );
Session session = jsch.getSession( "remote-username", "remote-host" );
{
// "interactive" version
// can selectively update specified kNown_hosts file
// need to implement UserInfo interface
// MyUserInfo is a swing implementation provided in
// examples/Sftp.java in the JSch dist
UserInfo ui = new MyUserInfo();
session.setUserInfo(ui);
// OR non-interactive version. Relies in host key being in kNown-hosts file
session.setPassword( "remote-password" );
}
session.connect();
Channel channel = session.openChannel( "sftp" );
channel.connect();
ChannelSftp sftpChannel = (ChannelSftp) channel;
sftpChannel.get("remote-file", "local-file" );
// OR
InputStream in = sftpChannel.get( "remote-file" );
// process inputstream as needed
sftpChannel.exit();
session.disconnect();
