@Bean(name = "adapter")
public MessageProducerSupport mqttInbound() {
    MqttClientOptions options = MqttConfiguration.getBasicClientOptions();
    MqttPahoMessageDrivenChannelAdapter adapter = new MqttPahoMessageDrivenChannelAdapter(
            options.getClientId() + "_consumer_" + System.currentTimeMillis(),
            mqttClientFactory, options.getInboundTopic().split(","));
    DefaultPahoMessageConverter converter = new DefaultPahoMessageConverter();
    // use byte types uniformly
    converter.setPayloadAsBytes(true);
    adapter.setConverter(converter);
    adapter.setQos(0);
    adapter.setOutputChannel(inboundChannel);
    return adapter;
}

我把qos调整为 0 或者 2，感觉没有生效，osd的消息还是一直是两条

  上云API上报osd属性消息不回上报两条重复的消息，有收到消息的截图吗？使用后端代码和mqtt客户端测试都没有这个问题。
