Rabbitmq 尽管DefaultRequeueRejected=false，rabbit代理中的消息仍然未确认

我的场景：我向我的兔子代理发布了两条消息，在处理第一条消息时发生了一个未经处理的异常

我的问题是：为什么消息在代理中保持未确认状态，因此为什么第二条消息没有被排队和处理

一些信息： 我正在使用SpringAMQP1.5.4和SpringIntegration4.2.4。请参阅下面的代码 我已设置死信交换，并且它正在按预期工作，即当我收到消息时，它将转发到DLX，并在那里过期。然后将其转发到主交换机

我想要的是： 我希望未处理的异常（即SimpleMessageListenerContainer捕获的异常）会导致amqp消息被Nack'd而不是保持未确认状态

我看到： 有3次重试尝试处理该消息，但由于我的强制异常而失败，请参阅下面的ErrorHandler中的代码

BlockingQueueConsumer的consumer标记是相同的，因此我猜BlockingQueueConsumer没有重新启动。但是，下面的日志显示它确实在继续等待消息

我想知道为什么BlockingQueueConsumer没有nack消息，为什么后续消息没有被消费，尽管日志中有证据表明消费者正在等待消息

欢迎提供任何建议或背景信息

对于手动确认，您负责确认或拒绝消息；如果将模式设置为自动，则容器将仅确认/确认；然后它将完全按照您的要求运行。

谢谢Gary。。。这就是我所需要做的一切。@Gary，你能帮我吗：我读了这篇文章，但SpringBoot似乎是我的另一种方法
