mqtt-spring-boot-start

mqtt启动器

1. 项目中引入依赖如下：
   

<dependency>
    <groupId>io.github.bigbigfeifei</groupId>
    <artifactId>mqtt-spring-boot-start</artifactId>
    <version>1.0</version>
</dependency>

2. nacos配置如下：
   

mqtt:
  mps:
    # 多个brokers用,分割即可：如：xxx1,xxx2,,,下面两个配置的是同一个topic,所以往这个topic上发送消息,这个两个client会收到消息,订阅会打收到两条一样的消息日志，生产一般设置不同的topic
    - brokers: tcp://192.168.40.47:1883
      userName: zlf1
      password: xxx1
      clientId: zlf1_publish
      topic: mqtt/test
      qos: 2
      type: publish
    - brokers: tcp://192.168.40.47:1883
      userName: zlf2
      password: xxx2
      clientId: zlf2_subscribe
      topic: mqtt/test
      qos: 2
      type: subscribe

3. 启动类上加入如下注解：
   3.1 @EnableMqtt //开启Mqtt
