解决rabbitmq 启动报错 Caused by: com.rabbitmq.client.ShutdownSignalException

?

?

报错信息如下:

?

Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; reason: {#method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - cannot redeclare exchange 'defaultExchange' in vhost '/' with different type, durable, internal or autodelete value, class-id=40, method-id=10), null, ""}

?

?

原因:

? ? ? ?rabbitmq服务通道是持久通道,该queue?已经存在,?而且通道属性跟最近修改后的属性不一致,而导致无法更新queue.?

?

解决办法:

? ? ? ?进入rabbitmq-management?将queue删除即可.
