Springboot整合mqtt服务的示例代码

作者：李泰山

MQTT是一个基于客户端-服务器的消息发布/订阅传输协议。MQTT协议是轻量、简单、开放和易于实现的，这些特点使它适用范围非常广泛。本文为大家分享了Springboot整合mqtt服务的示例代码，需要的可以参考一下

首先在pom文件里引入mqtt的依赖配置

        <!--mqtt-->
        <dependency>
            <groupId>org.eclipse.paho</groupId>
            <artifactId>org.eclipse.paho.client.mqttv3</artifactId>
            <version>1.2.4</version>
        </dependency>

其次在springboot 的配置yml文件，配置mqtt的服务配置

spring:  
  mqtt:
    url: tcp://127.0.0.1:1883
    client-id: niubility-tiger
    username:
    password:
    topic: [/unify/test]

创建 MqttProperties配置参数类

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
 
@Data
@ConfigurationProperties("spring.mqtt")
public class MqttProperties {
    private String url;
    private String clientId;
    private String username;
    private String password;
    private String[] topic;
}

创建 MqttConfiguration 配置类

import org.eclipse.paho.client.mqttv3.IMqttClient;
import org.eclipse.paho.client.mqttv3.MqttClient;
import org.eclipse.paho.client.mqttv3.MqttConnectOptions;
import org.eclipse.paho.client.mqttv3.MqttException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springblade.core.tool.utils.Func;
import org.springblade.ubw.listener.MqttSubscribeListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
@EnableConfigurationProperties({MqttProperties.class})
public class MqttConfiguration {
    private static final Logger log = LoggerFactory.getLogger(MqttConfiguration.class);
    @Autowired
    private MqttProperties mqttProperties;
 
    public MqttConfiguration() {
    }
 
    @Bean
    public MqttConnectOptions mqttConnectOptions() {
        MqttConnectOptions connectOptions = new MqttConnectOptions();
        connectOptions.setServerURIs(new String[]{this.mqttProperties.getUrl()});
        if (Func.isNotBlank(this.mqttProperties.getUrl())) {
            connectOptions.setUserName(this.mqttProperties.getUsername());
        }
 
        if (Func.isNotBlank(this.mqttProperties.getPassword())) {
            connectOptions.setPassword(this.mqttProperties.getPassword().toCharArray());
        }
 
        connectOptions.setKeepAliveInterval(60);
        return connectOptions;
    }
 
    @Bean
    public IMqttClient mqttClient(MqttConnectOptions options) throws MqttException {
        IMqttClient mqttClient = new MqttClient(this.mqttProperties.getUrl(), this.mqttProperties.getClientId());
        mqttClient.connect(options);
        for(int i = 0; i< this.mqttProperties.getTopic().length; ++i) {
            mqttClient.subscribe(this.mqttProperties.getTopic()[i], new MqttSubscribeListener());
        }
        return mqttClient;
    }
}

创建 订阅事件类

import org.springframework.context.ApplicationEvent;
 
 
public class UWBMqttSubscribeEvent extends ApplicationEvent {
    private String topic;
 
    public UWBMqttSubscribeEvent(String topic, Object source) {
        super(source);
        this.topic = topic;
    }
 
    public String getTopic() {
        return this.topic;
    }
}

创建订阅事件监听器

import org.eclipse.paho.client.mqttv3.IMqttMessageListener;
import org.eclipse.paho.client.mqttv3.MqttMessage;
import org.springblade.core.tool.utils.SpringUtil;
import org.springblade.ubw.event.UWBMqttSubscribeEvent;
 
 
public class MqttSubscribeListener implements IMqttMessageListener {
 
    @Override
    public void messageArrived(String s, MqttMessage mqttMessage) {
        String content = new String(mqttMessage.getPayload());
        UWBMqttSubscribeEvent event = new UWBMqttSubscribeEvent(s, content);
        SpringUtil.publishEvent(event);
    }
}

创建mqtt消息事件异步处理监听器

import com.baomidou.mybatisplus.core.toolkit.StringPool;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springblade.core.tool.utils.Func;
import org.springblade.ubw.config.MqttProperties;
import org.springblade.ubw.event.UWBMqttSubscribeEvent;
import org.springblade.ubw.service.MqttService;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.event.EventListener;
import org.springframework.scheduling.annotation.Async;
 
import javax.annotation.Resource;
import java.util.Arrays;
import java.util.List;
 
 
@Configuration
public class MqttEventListener {
 
 
    private static final Logger log = LoggerFactory.getLogger(MqttEventListener.class);
 
    @Resource
    private MqttProperties mqttProperties;
 
    @Resource
    private MqttService mqttService;
 
    private String processTopic (String topic) {
        List<String> topics = Arrays.asList(mqttProperties.getTopic());
        for (String wild : topics) {
            wild = wild.replace(StringPool.HASH, StringPool.EMPTY);
            if (topic.startsWith(wild)) {
                return topic.replace(wild, StringPool.EMPTY);
            }
        }
        return StringPool.EMPTY;
    }
 
 
    @Async
    @EventListener(UWBMqttSubscribeEvent.class)
    public void listen (UWBMqttSubscribeEvent event) {
        String topic = processTopic(event.getTopic());
        Object source = event.getSource();
        if (Func.isEmpty(source)) {
            return;
        }
        mqttService.issue(topic,source);
//        log.info("mqtt接收到 通道 {} 的信息为：{}",topic,source);
    }
}

创建MqttService 数据处理服务类

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springblade.core.tool.utils.Func;
import org.springblade.ubw.area.entity.WorkArea;
import org.springblade.ubw.area.entity.WorkSite;
