SFTP connection with FTPSClient is failing

问题

Below code I'm trying to connect SFTP host using FTPSClient. Instead of FTP client, I'm using FTPSClient to connect. But I'm facing issue to connect.

public static void main(String[] args) throws SocketException, IOException {
        String host ="sftphost.com";
        String user = "abc";
        String pwd  = "pwd"
        final FTPSClient ftp = new FTPSClient();        
        System.out.println("host:"+host);
        ftp.connect(host,22);       
        int reply = ftp.getReplyCode();
        ftp.login(user, pwd);
}

回答1:

FTPS is not SFTP.

You cannot use Apache Commons Net FTPS client FTPSClient to connect to SFTP port 22. That's a completely different protocol.

You have to use a different library. The most commonly used SFTP library for Java is JSch.
