在 spring cloud 项目中启动多个实例，希望消息能在多个实例中广播消费

2. Provide any additional detail on your proposed use case for this feature.
项目中用到了 websocket 推送，然后借助消息队列实现消息转发

```txt
A Producer -> sendMessage -> RocketMQ -> A PushConsumer 接受 -> websocket 发送到页面
-> B PushConsumer 接受 -> websocket 发送到页面
```
> A、B 为同一个服务的多个实例

我尝试按照文档使用多个 consumerGroup 但是会报错
