使用Java JSch SFTP文件传输(SFTP file transfer using Java

这是我的代码，以检索该文件内容，远程服务器和显示作为输出上。

package sshexample;

import com.jcraft.jsch.*;
import java.io.*;

public class SSHexample 
{
public static void main(String[] args) 
{
    String user = "user";
    String password = "password";
    String host = "192.168.100.103";
    int port=22;

    String remoteFile="sample.txt";

    try
    {
        JSch jsch = new JSch();
        Session session = jsch.getSession(user, host, port);
        session.setPassword(password);
        session.setConfig("StrictHostKeyChecking", "no");
        System.out.println("Establishing Connection...");
        session.connect();
        System.out.println("Connection established.");
        System.out.println("Creating SFTP Channel.");
        ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
        sftpChannel.connect();
        System.out.println("SFTP Channel created.");
        InputStream out= null;
        out= sftpChannel.get(remoteFile);
        BufferedReader br = new BufferedReader(new InputStreamReader(out));
        String line;
        while ((line = br.readLine()) != null) 
        {
            System.out.println(line);
        }
        br.close();
        sftpChannel.disconnect();
        session.disconnect();
    }
    catch(JSchException | SftpException | IOException e)
    {
        System.out.println(e);
    }
}
}

现在，如何实施这一计划，该文件在本地主机以及如何将文件从本地主机到服务器的复制拷贝。

这里如何使工作的文件的文件的任何格式传送。

Answer 1:

上传超过SFTP与JSch一个文件中最微不足道的方法是：

JSch jsch = new JSch();
Session session = jsch.getSession(user, host);
session.setPassword(password);
session.connect();

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

sftpChannel.put("C:/source/local/path/file.zip", "/target/remote/path/file.zip");

类似地，对于下载：

sftpChannel.get("/source/remote/path/file.zip", "C:/target/local/path/file.zip");

您可能需要处理UnknownHostKey例外 。

Answer 2:

用法：

sftp("file:/C:/home/file.txt", "ssh://user:pass@host/home");
sftp("ssh://user:pass@host/home/file.txt", "file:/C:/home");

下面的代码对我的作品

   public static void sftpsript(String filepath) {

 try {
  String user ="demouser"; // username for remote host
  String password ="demo123"; // password of the remote host

   String host = "demo.net"; // remote host address
  JSch jsch = new JSch();
  Session session = jsch.getSession(user, host);
  session.setPassword(password);
  session.connect();

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

  sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
  sftpChannel.disconnect();
  session.disconnect();
 }catch(Exception ex){
     ex.printStackTrace();
 }
   }
