如何使用Java通过SSH隧道连接远程MySQL数据库？

import com.jcraft.jsch.*;

public class SSHMySQLTunnel {

    public static void main(String[] args) throws Exception {
        // Replace with SSH server hostname
        String sshHost = "ssh.server.com";

        // SSH port number
        int sshPort = 22;

        // Replace with SSH username
        String sshUsername = "username";

        // Replace with SSH password
        String sshPassword = "password";

        // Replace with MySQL server hostname
        String mysqlHost = "mysql.server.com";

        // MySQL port number (assuming 3306)
        int mysqlPort = 3306;

        // Local port to forward to (1234 in this example)
        int localPort = 1234;

        JSch jsch = new JSch();
        Session session = jsch.getSession(sshUsername, sshHost, sshPort);
        session.setPassword(sshPassword);
        session.connect();

        int assingedPort = session.setPortForwardingL(localPort, mysqlHost, mysqlPort);

        System.out.println("SSH tunnel established. Forwarded port " + localPort + " to " + mysqlHost + ":" + mysqlPort);

        // Establish JDBC connection to MySQL using the tunnel
        String jdbcUrl = "jdbc:mysql://localhost:" + localPort + "/[database]";

        // ...
    }
}
