我正在使用AMQP连接器，并且我的队列存在于集群环境中。我不确定为什么总是填充此消息。但这并不影响任何成功运行流程。但它总是试图尝试连接。
我正在使用 Amqp 传输 jar:3.4.4 (即使我尝试使用最新的 jar 3.4.6 jar 导入)，同样的错误再次发生。 Amqp 客户端:3.2.1。 我完全糊涂了。 因为我尝试了集群中不存在的相同队列，所以它工作正常。 请建议我哪里做错了。
使用 Ack(手动)也更改为“MULE_AUTO”。无奈。

最佳答案
应该有一个传递标签流变量用于跟踪连接。需要该变量才能确认消息。我怀疑流量变量在某个时候会消失。如果 ACK 是在与流程开始的线程不同的单独线程中完成的，则可能会发生这种情况。原因是传递标签变量在移动到另一个线程时无法序列化/反序列化。
有什么事情是异步完成的吗？
