Spring cloud stream rabbit：当rabbit服务器不可用时创建队列

Question

我正在使用
spring-cloud d-stream： 3.1.4
spring-cloud d-stream-binder-兔子：3.1.4

我在“属性”下的此处配置了一个消费者。我的问题是，当使用者在rabbitmq服务器可用之前启动时，我可以看到使用者会重新启动，直到连接可用为止。然而，DLX和DLQ之间创建的绑定并不相同。

• 如果消费者启动时Rabbitmq可用：DLQ绑定到DLX，路由密钥为worker.request.queue.name和worker.request.dlq.name
• 如果消费者在重试后启动时Rabbitmq不可用：DLQ仅使用例程Key'worker.request.dlq.name'绑定到DLX。

问题是我需要两者都有约束力。任何人都可以帮助我理解我做错了什么？

谢谢

查看sprint cloud stream rabbit投标人代码后，我可以在以下位置看到问题：https://github.com/spring-cloud/spring-cloud-stream-binder-rabbit/blob/97c6f79fff15d985434e24c6b48c85caa962a4e6/spring-cloud-stream-binder-rabbit-core/src/main/java/org/springframework/cloud/stream/binder/rabbit/provisioning/RabbitExchangeQueueProvisioner.java#L659

每个队列/Exhcnage/绑定声明初始化一次，并在每次尝试后重试。但是声明列表是一个带有字符串键的bean映射。如果在同一队列上进行双重绑定，则密钥相同，因此只保存第一个声明。请参见此处：https://github.com/spring-cloud/spring-cloud-stream-binder-rabbit/blob/97c6f79fff15d985434e24c6b48c85caa962a4e6/spring-cloud-stream-binder-rabbit-core/src/main/java/org/springframework/cloud/stream/binder/rabbit/provisioning/RabbitExchangeQueueProvisioner.java#L629
