The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=406, text='PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'queue2' in vhost '/': received 'false' but current is 'true'', classId=50, methodId=10
因为已存在的队列“queue2” 是非持久化时 （durable=false）。
解决方法：
删除名为“queue2” 的队列
或
换个队列名，如“queue3” 。
