1、引入依赖

        
            org.springframework.boot
            spring-boot-starter-integration
        
        
            org.springframework.integration
            spring-integration-mqtt
        

2、MqttConfig

用于配置客户端信息

package com.tan.mqtt;

import com.tan.mqtt.logic.LogicService;
import lombok.extern.slf4j.Slf4j;
import org.eclipse.paho.client.mqttv3.MqttConnectOptions;
import org.springframework.beans.factory.annotation.Value;
