SpringBoot 整合RocketMQ

一：Ubuntu安装RocketMQ

Ubuntu 安装 Rocketmq_羁客%的博客-CSDN博客

二：添加RocketMQ依赖

    org.apache.rocketmq
    rocketmq-spring-boot-starter
    2.1.1
    
        
            org.springframework.boot
            spring-boot-starter
        
        
            org.springframework
            spring-core
        
        
            org.springframework
            spring-webmvc
        
    

三：在application中添加RocketMQ配置

#rocketmq 配置
rocketmq:
  name-server: 127.0.0.0:9876 #IP根据自己电脑服务器配置的 mqbroker->brokerIP1 修改一下，最好不要使用这个
  producer:
    group: rocketmq_group

myrocketmq-config:
  my-topic: rocketmq_topic
  my-consumer-group: rocketmq_group_consumer

四：编写消费者，消息生产者，消息实体类(自定义)

//Rocket消费者(Push 推送型消费者,被动型消费)
@Slf4j
@Component
@RocketMQMessageListener(consumerGroup = "${myrocketmq-config.my-consumer-group}", topic = "${myrocketmq-config.my-topic}")
public class RocketConsumer implements RocketMQListener {

    @Override
    public void onMessage(RocketmqVo rocketmqVo) {
        log.info("收到RocketMQ消息:{}",rocketmqVo);
    }
}

//Rocket生产者
@Slf4j
@Component
public class RocketProduce {

    @Value("${myrocketmq-config.my-topic}")
    private String mqTopic;
    @Value("${myrocketmq-config.my-consumer-group}")
    private String mqConsumerGroup;
    @Autowired
    private RocketMQTemplate mqTemplate;

    /**
     * 同步发送
     *
     * @param title 发送消息
     * @param data  消息内容
     */
    public void sync(String title, Object data) {
        String time = new SimpleDateFormat("yyyyMMdd HH:mm:ss").format(new Date());
        RocketmqVo rocketmqVo = new RocketmqVo(mqConsumerGroup, mqTopic, title, time, data);
        SendResult sendResult = mqTemplate.syncSend(mqTopic, rocketmqVo);
        log.info("同步发送:{}", rocketmqVo);
        log.info("同步发送消息结果:{}", sendResult);
    }

    /**
     * 异步发送
     *
     * @param title 发送消息
     * @param data  消息内容
     */
    public void async(String title, Object data) {
        String time = new SimpleDateFormat("yyyyMMdd HH:mm:ss").format(new Date());
        RocketmqVo rocketmqVo = new RocketmqVo(mqConsumerGroup, mqTopic, title, time, data);
        log.info("异步发送:{}", rocketmqVo);
        mqTemplate.asyncSend(mqTopic, rocketmqVo, new SendCallback() {
            @Override
            public void onSuccess(SendResult var1) {
                log.info("异步发送成功:{}", var1);
            }

            @Override
            public void onException(Throwable var1) {
                log.info("异步发送失败:{}", var1.getMessage());
            }
        });
    }

    /**
     * 单向发送
     *
     * @param title 发送消息
     */
    public void oneway(String title, Object data) {
        String time = new SimpleDateFormat("yyyyMMdd HH:mm:ss").format(new Date());
        RocketmqVo rocketmqVo = new RocketmqVo(mqConsumerGroup, mqTopic, title, time, data);
        mqTemplate.sendOneWay(mqTopic, rocketmqVo);
        log.info("单向发送:{}", rocketmqVo);
    }
}

//Rocket消息实体
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class RocketmqVo {

    @Value("${myrocketmq-config.my-consumer-group}")
    private String group;

    @Value("${myrocketmq-config.my-topic}")
    private String topic;

    private String title;

    private String date;

    private Object data;


    public RocketmqVo(String title, String date, Object data) {
        this.title = title;
        this.date = date;
        this.data = data;
    }
}

五：测试Controller

@RestController
@RequestMapping("/mqtest")
public class RocketController {

    @Resource
    private RocketProduce producer;

    @RequestMapping("/sendMessageSync/{msg}")
    public String sendMessageSync(@PathVariable("msg") String message) {
        producer.sync(message, null);
        return "消息发送完成";
    }

    @RequestMapping("/sendMessageAsync/{msg}")
    public String sendMessageAsync(@PathVariable("msg") String message) {
        producer.async(message, null);
        return "消息发送完成";
    }

    @RequestMapping("/sendMessageOneway/{msg}")
    public String sendMessageOneway(@PathVariable("msg") String message) {
        producer.oneway(message, null);
        return "消息发送完成";
    }
}
