一个应用只允许一个gid，但是有好几个消费类（不同业务不同的topic），导致订阅关系不一致

[hachikozjq]

如题，有没有好的解决方案？
@RocketMQMessageListener(
topic = "topic1",
consumerGroup = "spring-application-name",
messageModel = MessageModel.CLUSTERING
)
public class A{
}

@RocketMQMessageListener(
topic = "topic2",
consumerGroup = "spring-application-name",
messageModel = MessageModel.CLUSTERING
)
public class B{
}

难道要用一个类去监听所有的topic，然后再通过topic判断分别再去调用其他的类？

最简单的解决方案，不要让gid和应用绑定，gid本身就是一个消费组集群的概念，和应用不应该绑定。

The simplest solution is not to bind the gid with the application, as the gid itself represents the concept of a consumer group cluster and should not be tied to the application.

在rocketmq中，可以通过consumer多次调用subscribe，使得一个consumer能够同时订阅多个topic；阅读了一下rocketmq-spring的代码，org.apache.rocketmq.spring.support.DefaultRocketMQListenerContainer，看起来是不支持这种做法的。

In RocketMQ, a consumer can subscribe to multiple topics by calling the subscribe method multiple times, allowing a single consumer to simultaneously subscribe to multiple topics. After reviewing the code of rocketmq-spring, specifically org.apache.rocketmq.spring.support.DefaultRocketMQListenerContainer, it appears that this approach is not supported.

最后使用RocketMQPushConsumerLifecycleListener实现，写在了一个消费类里，多次subscribe，gid一个应用一个是公司限制，不允许自己创建。

可以将你的代码示例贴出来吗，这样别人碰到相同的问题看到你的issue也就可以解决了；
另外，group确实不应当和应用一对一绑定，可以是一个多对一的关系，从最佳实践来看，变更订阅关系的时候也是建议新建group来启用新的订阅关系

Can you post your code example? This way, others facing the same problem can find a solution when they see your issue. Additionally, it is indeed not advisable to bind a group one-to-one with an application; it can be a many-to-one relationship. From best practices, it is recommended to create a new group when changing subscription relationships to enable the new subscriptions.
