注释类型 MqttMessageListener

@Target(value=TYPE)
 @Retention(value=RUNTIME)
 @Documented
public @interface MqttMessageListener

在监听者上标注该注解, 然后实现 IMqttMessageListener 接口

示例代码如下

  @Component
  @MqttMessageListener(topic = "test1", qos = QosEnum.QoS1)
 public class Demo1Listener implements IMqttListener, MqListener {
     private static final Logger log = LoggerFactory.getLogger(Demo1Listener.class);
      @Override
     public void onMessage(String topic, String message) {
         log.info("topic: {}, message: {}", topic, message);
     }
 }
