rabbitmq - Spring RabbitMQ - 在 MessageListener 中获取 ClassCastException

Question

我在使用 Spring RabbitMQ 时从 AMQP 内部获取 ClassCastException。我们在生产的应用程序日志中发现了这一点，无法重现，但这对我们来说真的很痛苦。基本上，一旦发生这种情况，似乎整个堆栈都会失败，因为我们看到在该通道上发送了无效的 DeliveryTag，这导致 RabbitMQ 关闭该通道。

我们使用的是 AMQPClient 5.4.3 和 SpringRabbit 2.1.2，RabbitMQ 缓存模式是 Connection（因为 HAProxy 和故障转移），ACK 模式是手动的，发布者返回启用并且发布者确认也是如此。

这对我来说完全是个谜。有谁知道出了什么问题？

RabbitMQ 客户端可以配置为检查 RPC 的响应类型channelShouldCheckRpcResponseType，另请参见https://github.com/rabbitmq/rabbitmq-java-client/issues/708。
