Writing code in java: How to upload files to the server in the form of sftp?

In Java, you can use the JSch library to upload files to the server via SFTP (SSH File Transfer Protocol). Here is a sample code showing how to use the JSch library for SFTP file upload:

import com.jcraft.jsch.*;

public class SftpUploader {     public static void main(String[] args) {         String host = "server hostname";         int port = 22;         String username = "username";         String password = "password";         String localFilePath = "local file Path";         String remoteFilePath = "Remote server file path";

        JSch jSch = new JSch();
        Session session = null;
        ChannelSftp channelSftp = null;
        
        try {
            session = jSch.getSession(username, host, port);
            session.setPassword(password);
            session.setConfig("StrictHostKeyChecking", "no");
            session.connect();

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

            channelSftp.put(localFilePath, remoteFilePath); // Upload file
            System.out.println("File uploaded successfully");
        } catch (JSchException | SftpException e) {             e.printStackTrace();         } finally {             if (channelSftp != null && channelSftp.isConnected()) {                 channelSftp.disconnect();             }             if (session != null && session.isConnected()) {                 session.disconnect();             }         } }     }

服务器主机名Make sure to replace , 用户名, 密码, 本地文件路径and in the code 远程服务器文件路径with actual values. This example assumes you have added the JSch library to your project's classpath.
