使用jsch 实现ssh tunnel

主要目的是解决比如访问敏感信息，我们通过加密隧道实现数据访问，而且对于数据进行加密

import com.jcraft.jsch.JSch;

import com.jcraft.jsch.Session;

 

public class App {

 

    public void go() throws Exception {

        String host = "<sship>";

        String user ="<user>>";

        String password = "<password>";

        int port = 22;

        int tunnelLocalPort = 9080;

        String tunnelRemoteHost = "<containerip>";

        int tunnelRemotePort = 3306;

        JSch jsch = new JSch();

        Session session = jsch.getSession(user, host, port);

        session.setPassword(password);

        LocalUserInfo lui = new LocalUserInfo();

        session.setUserInfo(lui);

        session.connect();

        session.setPortForwardingL(tunnelLocalPort, tunnelRemoteHost, tunnelRemotePort);

        System.out.println("Connected");

    }

 

    public static void main(String[] args) throws Exception {

        App app = new App();

        app.go();

    }

} 

说明

以上代码能实现很简单，但是可以解决我们实际对于加密信息的访问，实际上好多基于容器的调试也会选择基于ssh tunnel 实现
