SpringBoot整合阿里云RocketMQ对接,商业版

1.需要阿里云开通商业版RocketMQ

普通消息新建普通主题,普通组,延迟消息新建延迟消息主题,延迟消息组

2.结构目录

3.引入依赖

<!--阿里云RocketMq整合-->
        <dependency>
            <groupId>com.aliyun.openservices</groupId>
            <artifactId>ons-client</artifactId>
            <version>1.8.8.5.Final</version>
        </dependency>

4.延迟消息配置

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.HashMap;
import java.util.Map;
import java.util.Properties;

/**
 * 延迟消息配置类
 */
@Configuration
public class BatchConsumerClient {

    @Autowired
    private MqConfig mqConfig;

    @Autowired
    private BatchDemoMessageListener messageListener;

    @Bean(initMethod = "start", destroyMethod = "shutdown")
    public BatchConsumerBean buildBatchConsumer() {
        BatchConsumerBean batchConsumerBean = new BatchConsumerBean();
        //配置文件
        Properties properties = mqConfig.getMqPropertie();
        properties.setProperty(PropertyKeyConst.GROUP_ID, mqConfig.getDelayGroupId());
        //将消费者线程数固定为20个 20为默认值
        properties.setProperty(PropertyKeyConst.ConsumeThreadNums, "20");
        batchConsumerBean.setProperties(properties);
        //订阅关系
        Map<Subscription, BatchMessageListener> subscriptionTable = new HashMap<Subscription, BatchMessageListener>();
        Subscription subscription = new Subscription();
        subscription.setTopic(mqConfig.getDelayTopic());
        subscription.setExpression(mqConfig.getDelayTag());
        subscriptionTable.put(subscription, messageListener);
        //订阅多个topic如上面设置
        batchConsumerBean.setSubscriptionTable(subscriptionTable);
        return batchConsumerBean;
    }

}

        for (Message message : messages) {
            byte[] body = message.getBody();
            String s = new String(body);
            Date date = new Date();
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            String formatTime = sdf.format(date);
            System.out.println("接收到消息时间:"+formatTime);
            log.info("接收到消息内容:"+s);
        }
        try {
            //do something..
            return Action.CommitMessage;
        } catch (Exception e) {
            //消费失败
            return Action.ReconsumeLater;
        }
    }
}
