我发现完整的工作示例SFTP在java使用JSCH API http://kodehelp.com/java-program-for-uploading-file-to-sftp-server/

hierynomus/sshj有一个完整的SFTP版本3的实现(OpenSSH实现的)

来自SFTPUpload.java的示例代码

package net.schmizz.sshj.examples;

import net.schmizz.sshj.SSHClient;
import net.schmizz.sshj.sftp.SFTPClient;
import net.schmizz.sshj.xfer.FileSystemFile;

import java.io.File;
import java.io.IOException;

/** This example demonstrates uploading of a file over SFTP to the SSH server. */
public class SFTPUpload {

    public static void main(String[] args)
            throws IOException {
        final SSHClient ssh = new SSHClient();
        ssh.loadKnownHosts();
        ssh.connect("localhost");
        try {
            ssh.authPublickey(System.getProperty("user.name"));
            final String src = System.getProperty("user.home") + File.separator + "test_file";
            final SFTPClient sftp = ssh.newSFTPClient();
            try {
                sftp.put(new FileSystemFile(src), "/tmp");
            } finally {
                sftp.close();
            }
        } finally {
            ssh.disconnect();
        }
    }

}

另一种选择是考虑查看JSch库。JSch似乎是一些大型开源项目的首选库，包括Eclipse、Ant和Apache Commons HttpClient等等。

它很好地支持用户/通行证和基于证书的登录，以及所有其他漂亮的SSH2特性。

这是一个简单的远程文件检索SFTP。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();

这就是我想到的解决办法 http://sourceforge.net/projects/sshtools/(为了清晰起见，省略了大多数错误处理)。这是我博客的节选

SshClient ssh = new SshClient();
ssh.connect(host, port);
//Authenticate
PasswordAuthenticationClient passwordAuthenticationClient = new PasswordAuthenticationClient();
passwordAuthenticationClient.setUsername(userName);
passwordAuthenticationClient.setPassword(password);
int result = ssh.authenticate(passwordAuthenticationClient);
if(result != AuthenticationProtocolState.COMPLETE){
     throw new SFTPException("Login to " + host + ":" + port + " " + userName + "/" + password + " failed");
}
//Open the SFTP channel
SftpClient client = ssh.openSftpClient();
//Send the file
client.put(filePath);
//disconnect
client.quit();
ssh.disconnect();
