Dreamroute opened a new issue, #468:
URL: https://github.com/apache/rocketmq-spring/issues/468
我有个消费者：
```java
@Component
@RocketMQMessageListener(topic = "xxx", consumerGroup = "yyy")
public class MyConsumer implements RocketMQListener<String> {}
```
1. `consumerGroup
`的值（上方`yyy`处）只有为：`Consumer1`和`Consumer2`，此消费者才生效，其他任何名字都无法消费消息；
2. `console`报错为`unknow`：
3. 异常信息如下：
4. console的消费者信息（consumer manage）是空的：
这个问题给我的感觉有点像是 rocketmq的nameserver或者broker把consumer
group限制死了一样，似乎只能使用被限制的那几个名称，而其他名称都不生效一样。
请问：这是什么原因呢？我百思不得其解。
