我试图通过创建MethodInterceptor channel.basicReject()并将其添加到SMLC ConsumerAdvice来基于某种条件来factor.setAdviceChain(new ConsumerAdvice())重新排队消息。我还具有设置为10的并发消费者配置。当我的拒绝条件得到满足时，我发出basicReject命令，它被另一个使用者重新传递和处理。在重新交付过程中，出现以下错误，

我的消息并没有丢失，但是我看到了很多上述错误，无法理解为什么会这样。如果有人有任何线索，请指导我。

您需要显示代码和配置。
SMLC似乎具有自动确认消息的默认配置，而此失败是因为您已经拒绝了它；您为什么直接与该频道进行交互？
您可以简单地引发异常，容器将代表您拒绝该消息。

我不知道它是否对某人有帮助。
由于输入数据无效，我遇到了同样的错误。但是当我添加下一个属性时：
"rabbit.listener.acknowledgeMode": "MANUAL",
"rabbit.listener.defaultRequeueRejected": "true",
"rabbit.listener.prefetchCount": "1",
问题停止破坏我的程序，但只停止了我的听众
