我需要有关连接 SFTP 服务器的帮助吗？有人有工作代码吗？
我发现了这样的东西
package test.JSch;
import com.jcraft.jsch.*;
public class TestJSch {
public static void main(String args[]) {
JSch jsch = new JSch();
Session session = null;
try {
session = jsch.getSession("USSERNAME", "HOST", 22);
//session.setConfig("StrictHostKeyChecking", "no");
session.setPassword("PASSWORD");
System.out.println("1");
session.connect();
System.out.println("2");
Channel channel = session.openChannel("sftp");
System.out.println("3");
channel.connect();
System.out.println("4");
ChannelSftp sftpChannel = (ChannelSftp) channel;
sftpChannel.get("remotefile.txt", "localfile.txt");
sftpChannel.exit();
session.disconnect();
} catch (JSchException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
} catch (SftpException e) {
e.printStackTrace();
}
}
}
但这是输出

这段代码有什么问题？
您可以尝试增加 Jsch Framework 的超时时间。
session.connect(int Timeout)
session.connect(30000);
