Java 如何通过SFTP从服务器检索文件？

Java 如何通过SFTP从服务器检索文件？

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" );// ORInputStream in = sftpChannel.get( "remote-file" );  // process inputstream as neededsftpChannel.exit();session.disconnect();
