使用JSCH将文件从一个远程服务器发送到另一个使用JSCH的服务器

import com.jcraft.jsch.*;

public class FileUploader {
    public static void main(String[] args) {
        String remoteHost = "remote.example.com";
        int remotePort = 22;
        String remoteUsername = "username";
        String remotePassword = "password";
        
        String localFilePath = "/path/to/local/file.txt";
        String remoteDir = "/path/to/remote/dir/";
        
        JSch jsch = new JSch();
        try {
            // 建立SSH连接
            Session session = jsch.getSession(remoteUsername, remoteHost, remotePort);
            session.setPassword(remotePassword);
            session.setConfig("StrictHostKeyChecking", "no");
            session.connect();
            
            // 创建SFTP通道
            Channel channel = session.openChannel("sftp");
            channel.connect();
            
            ChannelSftp sftpChannel = (ChannelSftp) channel;
            
            // 切换到远程服务器的目录
            sftpChannel.cd(remoteDir);
            
            // 上传文件
            sftpChannel.put(localFilePath, "uploaded_file.txt");
            
            // 关闭连接
            sftpChannel.disconnect();
            session.disconnect();
            
            System.out.println("File uploaded successfully!");
        } catch (JSchException | SftpException e) {
            e.printStackTrace();
        }
    }
