@Test

    String hostname = "127.0.0.1", username = "yuwen", password = "lyp82nlf";
    int port = 3306;
    // BinaryLogClient其实就是一个连接数据库的客户端,
    // 它加自己伪装成slave 连接到master上
    BinaryLogClient client = new BinaryLogClient(
            hostname, port, username, password
    );
    // 设置监听的Binlog, 如果不设置则监听最新的Binlog
    //client.setBinlogFilename();
    // 设置监听的binlog位置, 如果不设置则监听最新的位置
    //client.setBinlogPosition();
    // 注册事件监听器, 监听期间MySQL发生的一些变化, Event代表已经发生的事件
    client.registerEventListener(event -> {
        // MySQL 数据表发生变化的一些数据
        EventData eventData = event.getData();
        if (eventData instanceof UpdateRowsEventData) {
            log.info("update event");
            log.debug("{}", eventData);
        } else if (eventData instanceof WriteRowsEventData) {

        }
    });
    // 连接到 master 开始监听
    client.connect();


    // 启动后手动连接到 MySQL执行
    // insert into `ad_unit_keyword` (`unit_id`, `keyword`) values (10, '标志');
    // 控制台得到日志
