java+sftp创建多级目录

以下是Java使用JSch库创建多级目录的示例代码：

import com.jcraft.jsch.*;

public class SftpCreateDirectories {
    public static void main(String[] args) {
        String host = "your_sftp_host";        int port = 22;
        String username = "your_username";        String password = "your_password";
        String remoteDirectoryPath = "/path/to/remote/directory";

        JSch jsch = new JSch();
        Session session = null;
        ChannelSftp channelSftp = null;

        try {
            session = jsch.getSession(username, host, port);
            session.setConfig("StrictHostKeyChecking", "no");
            session.setPassword(password);            session.connect();

            channelSftp = (ChannelSftp) session.openChannel("sftp");
            channelSftp.connect();

            String[] directories = remoteDirectoryPath.split("/");
            for (String directory : directories) {
                if (directory.length() > 0) {
                    try {
                        channelSftp.cd(directory);
                    } catch (SftpException e) {
                        channelSftp.mkdir(directory);
                        channelSftp.cd(directory);
                    }
                }
            }

            System.out.println("Directories created successfully.");
        } catch (JSchException | SftpException e) {
            e.printStackTrace();
        } finally {
            if (channelSftp != null) {
                channelSftp.disconnect();
            }
            if (session != null) {
                session.disconnect();
            }
        }
    }
}

这段代码使用JSch库连接到SFTP服务器，并在远程服务器上创建多级目录。它首先将远程目录路径拆分为目录名称数组，然后遍历该数组并尝试进入每个目录。如果目录不存在，则创建该目录。
