SSHJ上传sftp

以下是使用SSHJ库在Java中上传SFTP的示例代码：

import net.schmizz.sshj.SSHClient;
import net.schmizz.sshj.sftp.SFTPClient;
import java.io.IOException;

public class SFTPUploader {

    public static void main(String[] args) {
        String remoteFile = "remote_sftp_test/jschFile.txt";
        String localFile = "src/main/resources/sample.txt";
        String remoteDir = "remote_sftp_test/";

        SSHClient sshClient = new SSHClient();
        try {
            sshClient.loadKnownHosts(); // 加载已知的主机密钥
            sshClient.connect("hostname", 22); // 替换为实际的主机名和端口号
            sshClient.authPassword("username", "password"); // 替换为实际的用户名和密码

            SFTPClient sftpClient = sshClient.newSFTPClient();
            sftpClient.put(localFile, remoteDir + "sshjFile.txt"); // 上传文件
            sftpClient.close();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                sshClient.disconnect();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

请注意，你需要将代码中的"hostname"、22、"username"和"password"替换为实际的主机名、端口号、用户名和密码。
