SpringBoot整合RockeyMQ

    1:添加依赖,安装的什么版本就添加什么版本的依赖包,不然要手动创建topic

<!--RockeyMQ-->
<dependency>
  <groupId>org.apache.rocketmq</groupId>
  <artifactId>rocketmq-client</artifactId>
  <version>4.4.0</version>
</dependency>

2:编写生产者案例

@Component
public class PayProduct {

    private DefaultMQProducer defaultMQProducer;

    public DefaultMQProducer getProducer() {
        return this.defaultMQProducer;
    }

    public PayProduct() {
        //设置生产者组名称
        defaultMQProducer = new DefaultMQProducer(JmsConfig.productGroup);

        //设置连接地址
        defaultMQProducer.setNamesrvAddr(JmsConfig.nameServerAddr);
        strat();
    }

    //开启服务,只在启动一次
    private void strat() {
        try {
            this.defaultMQProducer.start();
        } catch (MQClientException e) {
            e.printStackTrace();
        }
    }

    //关闭服务  一般在上下文关闭
    public void shutdown() {
        defaultMQProducer.shutdown();
    }

}

2:编写消费者案例

@Component
public class PayConsumerMasser {

    private DefaultMQPushConsumer defaultMQPushConsumer;

    public PayConsumerMasser() {
        //消费组
        defaultMQPushConsumer = new DefaultMQPushConsumer(JmsConfig.consumerGroup);
        //外网连接地址
        defaultMQPushConsumer.setNamesrvAddr(JmsConfig.nameServerAddr);
        //设置从哪里开始消费
        defaultMQPushConsumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_LAST_OFFSET);

        try {
            //接收topic
            defaultMQPushConsumer.subscribe(JmsConfig.messageTop, JmsConfig.messageTogs);
        } catch (MQClientException e) {
            e.printStackTrace();
        }
        defaultMQPushConsumer.registerMessageListener(new MessageListenerConcurrently() {
            @Override
            public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> list, ConsumeConcurrentlyContext consumeConcurrentlyContext) {
                MessageExt messageExt = list.get(0);
                int reconsumeTimes = messageExt.getReconsumeTimes(); //重试次数
                try {
                    System.out.println("重试次数" + reconsumeTimes);

                    String body = new String(messageExt.getBody(), "utf-8");

                    Map<String, Object> map = JSON.parseObject(body, Map.class);
                    String context = (String) map.get("context"); //消息内容
                    String mobile = (String) map.get("mobile"); //手机号码
                    SmsUtil.getSmsEval(mobile, context,1);
                    return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
                } catch (Exception e) {
                    //发送失败,不進行重試
                    if (reconsumeTimes > 0) {
                        return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
                    }
                    e.printStackTrace();
                    return ConsumeConcurrentlyStatus.RECONSUME_LATER;
                }
            }
        });
        try {
            defaultMQPushConsumer.start();
        } catch (MQClientException e) {
            e.printStackTrace();
        }


    }
}

问题 1:

org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException:

sendDefaultImpl call timeout

原因是阿里云存在多个网卡,rockeyMQ会根据当前的网卡选择一个ip使用,当机器有多个网卡的时候,就会出现这个问题,一个是公网ip,一个是私网ip,这要配置briker.conf
配置指定的公网ip,然后进行重启vroker.conf

在conf/broker.conf 新增一个配置   brokerIP1=公网ip

已配置文件方式启动

nohup sh bin/mqbroker -n localhost:9876 -c ./conf/broker.conf &
