业务应用场景

消息队列的应用场景:主要用于处理高并发作削峰处理、业务解耦等,比如说 大规模的短信推送、订单抓取、库存同步、消息同步等。

 

下载

wget https://archive.apache.org/dist/rocketmq/4.5.1/rocketmq-all-4.5.1-bin-release.zip

安装

unzip rocketmq-all-4.5.1-bin-release.zip

启动

cd rocketmq-all-4.5.1-bin-release/bin

启动nameServer、并验证

nohup sh mqnamesrv &

tail -f ~/logs/rocketmqlogs/namesrv.log

# 如果成功启动,能看到类似如下的日志:
2019-07-18 17:03:56 INFO main - The Name Server boot success. ...

 

启动Broker 并验证 (如果启动失败,调整内存参数)

nohup sh mqbroker -n localhost:9876 autoCreateTopicEnable=true &

tail -f ~/logs/rocketmqlogs/broker.log

# 如果启动成功,能看到类似如下的日志:
2019-07-18 17:08:41 INFO main - The broker[itmuchcomdeMacBook-Pro.local, 192.168.43.197:10911] boot success. serializeType=JSON and name server is localhost:9876

 

关闭MQ

sh mqshutdown namesrv


注意

如果一直报错 172.17.0.11:10911 连接失败,需要新增ip配置文件并指定

brokerIP1=xxx

 

nohup sh mqbroker -n 172.17.0.11:9876 autoCreateTopicEnable=true -c conf/broker.conf &

 

实战

 

pom依赖

        org.apache.rocketmq
            rocketmq-spring-boot-starter
            2.1.1

  

 

发送消息

    @Resource
    private RocketMQTemplate rocketMQTemplate;

    @Value("${pet.topic.order}")
    private String orderTopic;

    @Scheduled(cron = "0 0 0 1/1 * ? ")
    public void send() {
        rocketMQTemplate.syncSendOrderly(orderTopic, "这是一条MQ消息", UUID.randomUUID().toString());
        log.info("MQ发送消息成功");
    }

  

 

接收消息

package agatha.pet.mq;

import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;

/**
 * @author oak
 * @date 2021/1/11
 */
@Slf4j
@Component
@RocketMQMessageListener(consumerGroup = "pet_group", topic = "${pet.topic.order}")
public class OrderConsumer implements RocketMQListener {

    @Override
    public void onMessage(String msg) {
        log.info("MQ.order.msg:{}", msg);
    }

}
