  // 创建 topics
    try (final ISubscriptionTableSession session =  new SubscriptionTableSessionBuilder()
                         .host(host)
                         .port(port)
                         .username(user)
                         .password(password)
                         .build())
    {
        final Properties config = new Properties();
        config.put(TopicConstant.DATABASE_KEY, "酸奶");
        config.put(TopicConstant.TABLE_KEY, "金山_产线_灌装_老酸奶灌装机");
        config.put(TopicConstant.START_TIME_KEY, "now");
        config.put(TopicConstant.STRICT_KEY, "true");
        config.put(TopicConstant.MODE_KEY, TopicConstant.MODE_DEFAULT_VALUE);
        session.createTopic("test_topic", config);
        log.info("主题 {} 创建成功", "test_topic");
    }

    ThreadUtil.execute(() -> {
        // 创建消费者
        // push 模式
        final ISubscriptionTablePushConsumer consumer = new SubscriptionTablePushConsumerBuilder()
                .consumerId("c1").consumerGroupId("cg1")
                .host(host).port(port)
                .username(user).password("root")
                .consumeListener(message -> {
                    System.out.println( message );
                    return ConsumeResult.SUCCESS;
                })
                .build();
        try {
            Thread.currentThread().join();
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }
    });

以上代码中 我拿不到 实时数据。我的实时数据是通过iotdb 自带的 mqtt 写进去的。每次写进去 执行select 查询的时候已经查到新数据了。但是 这个订阅始终收不到数据。
