mqtt java springboot

MQTT是一种轻量级的消息传递协议，常用于物联网和传感器网络中。在Java Spring Boot中，你可以使用Spring Integration MQTT来实现与MQTT代理的连接和消息的发布和订阅。首先，你需要在你的项目中添加相关的依赖。你可以在pom.xml文件中添加以下依赖项：

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-mqtt</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.eclipse.paho</groupId>
    <artifactId>org.eclipse.paho.client.mqttv3</artifactId>
    <version>1.2.0</version>
</dependency>

接下来，你可以创建一个Mqtt类，并实现CommandLineRunner接口。在run方法中，你可以通过@Autowired注解注入所需的依赖项，并在这里启动MQTT连接。例如，你可以启动你的数据库和Redis连接，以及其他相关的服务。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
