添加客户端监听

@Component
@RocketMQMessageListener(consumerGroup = "consumer-group", topic = "topic")
public class ConsumerListener implements RocketMQListener<MessageExt> {

    @Override
    public void onMessage(MessageExt message) {
        try {
            String messageKey = message.getKeys();

        }catch (Exception e){
            //重试次数
            int reconsumeTimes = message.getReconsumeTimes();
            if(reconsumeTimes >= 3){
                //重试之后依然失败的，保存到数据库

            }
        }
    }
}

启动报错

去掉

@Component注解就可以启动成功，添加了之后就启动报错

解决方法

在pom.xml文件中添加rocketmq-client依赖

<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-client</artifactId>
    <version>4.8.0</version>
</dependency>

重新启动，成功解决问题
