java jsch远程执行shell脚本命令

由于需要远程监控一些Linux主机的运行情况，需要通过java远程执行一些shell脚本，并获取返回值，可以通过jsch实现

jsch jar包下载地址：http://sourceforge.net/projects/jsch/files/jsch.jar/0.1.51/jsch-0.1.51.jar/download

public static void SSHCommand(String host,String user,String pass,int port,String command){
		
		JSch jsch = new JSch();

		Session session=null;
		Channel channel=null;
		try {
			session = jsch.getSession(user, host, port);
			session.setPassword(pass);
			session.setTimeout(2000);
			Properties config = new Properties();
			config.put("StrictHostKeyChecking", "no");
			session.setConfig(config);
			session.connect();
			channel = session.openChannel("exec");
			ChannelExec execChannel = (ChannelExec)channel;
			execChannel.setCommand(command);
			InputStream in = channel.getInputStream();
			channel.connect();
			
			StringBuffer sb = new StringBuffer();
			int c = -1;
			while((c = in.read()) != -1){
				sb.append((char)c);
			}
			System.out.println("输出结果是："+sb.toString());
			
			in.close();
		} catch (JSchException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} finally{
			channel.disconnect();
			session.disconnect();
		}
		
	}

 当然还可以通过sftp上传文件

public static boolean upload(String host, String username, String password, int port, String location,File uploadFile){
		Session session;
		Channel channel;
		Channel channelExec;
		JSch jsch = new JSch();
		try {
			session = jsch.getSession(username, host, port);
			session.setPassword(password);
			
			Properties config = new Properties();
			config.put("StrictHostKeyChecking", "no");
			session.setConfig(config);
			
			session.connect();
			channel = session.openChannel("sftp");
			channel.connect();
			ChannelSftp c = (ChannelSftp)channel;
			c.cd(location);
		    c.put(new FileInputStream(uploadFile),uploadFile.getName());
		   
		    //-------------------------
			c.disconnect();
			session.disconnect();
			return true;
		} catch (JSchException e) {
			e.printStackTrace();
		} catch (SftpException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
		return false;
	}
