使用Java JSch进行SFTP文件传输

这是我的代码，它在远程服务器上检索文件的内容并显示为输出。

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，如何实现此文件在localhost中复制的程序以及如何将文件从localhost复制到服务器。

这里如何为任何格式的文件传输文件。

Answer 1

使用JSch通过SFTP上传文件的最简单方法是：

 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"); 

同样下载：

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

您可能需要处理UnknownHostKeyexception 。

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");

下面的代码适合我

  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(); } }
