RabbitMQ保持日志记录
=ERROR REPORT==== 24-Aug-2014::06:25:07 ===
connection <0.109.6880>, channel 1 - soft error:
{amqp_error,precondition_failed,"unknown delivery tag 1",'basic.ack'}
日志文件相当大
您正在打包错误的交付标签，该标签已被打包或在当前渠道中从未存在。
在我的例子中，我的消费者启用了autoAck，并且在处理后也手动确认消息。手动确认抛出了与您遇到的相同的错误。
一旦我删除了手动确认，我就不会再看到错误了。
添加到@pinepain的答案，双确认抛出一个异常，并关闭这些相关的RabbitMQ文档的通道:
When manual acknowledgements are used, it is important to consider what thread does the acknowledgement. If it's different from the thread that received the delivery (e.g. Consumer#handleDelivery delegated delivery handling to a different thread), acknowledging with the multiple parameter set to true is unsafe and will result in double-acknowledgements, and therefore a channel-level protocol exception that closes the channel. Acknowledging a single message at a time can be safe.
