接收成功但是日志显示messageGroup=null
group为空，为什么控制台还能打印NormalTopicConsumer,接收成功:MessageViewImpl{messageId=0100155D939C9A3C18088D7E5500000000.....

换**rocketmq-spring-boot-starter**状态变成CONSUMED

Start with the rocketmq-spring-boot-starter configuration, @RocketMQMessageListener usage, and MessageView.getMessageGroup in the provided producer and consumer example. Reproduce the NormalTopic flow and compare the received MessageView and console status before and after changing the starter; done means explaining or correcting why messageGroup is empty while consumption succeeds.
