Java用ssh连接远程服务器

1, 建立一个maven工程，引入JSch

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

2. code

package omg;


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

public class Shell {
	private static InputStream in = null;

	public static void main(String[] arg) {

		try {
			JSch jsch = new JSch();

			Session session = jsch.getSession("xxx", "150.236.223.66", 22);

			String passwd = "xxxx###";
			session.setPassword(passwd);

			UserInfo ui = new MyUserInfo() {
				public void showMessage(String message) {
					JOptionPane.showMessageDialog(null, message);
				}

				public boolean promptYesNo(String message) {
					return true;
				}
			};

			session.setUserInfo(ui);
			session.connect(30000);

			Channel channel = session.openChannel("shell");
			((ChannelShell) channel).setPty(false);

			in = channel.getInputStream();
			OutputStream out = channel.getOutputStream();

			String command = "ls \n";

			channel.connect(3 * 1000);

			out.write(command.getBytes());
			out.flush();

			ReadThread readThread = new ReadThread();
			readThread.start();

		} catch (Exception e) {
			System.out.println(e);
		}
	}

	public static abstract class MyUserInfo implements UserInfo,
			UIKeyboardInteractive {
		public String getPassword() {
			return null;
		}

		public boolean promptYesNo(String str) {
			return false;
		}

		public String getPassphrase() {
			return null;
		}

		public boolean promptPassphrase(String message) {
			return false;
		}

		public boolean promptPassword(String message) {
			return false;
		}

		public void showMessage(String message) {
		}

		public String[] promptKeyboardInteractive(String destination,
				String name, String instruction, String[] prompt, boolean[] echo) {
			return null;
		}
	}

	private static class ReadThread extends Thread {

		@Override
		public void run() {
			while (true) {
				try {
					int i = 0;
					while ((i = in.read()) != -1) {
						char c = (char) i;

						System.out.print(c);
					}
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}

	}
