(reply-code=406 reply-text=PRECONDITION_FAILED - unknown delivery tag 1 class-id=60 method-id=80)

RabbitMQ 报错：channel is already closed due to channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - unknown delivery tag 1, class-id=60, method-id=80)

错误说这一行错误了

//手动回执信息try {channel.basicAck(delivery.getEnvelope().getDeliveryTag(),false);}catch (Exception e){e.printStackTrace();}

找到错误点

因为是true

channel.basicConsume(queue,true,deliverCallback,consumerTag ->{ });

解决

把true改成false 就成功了

channel.basicConsume(queue,false,deliverCallback,consumerTag ->{ });

成功了
