在服务器上安装了一个RabbitMq,并新创建了一个用户授予了管理员角色，登录控制台查看一切正常，兴高采烈启动项目进行连接，结果一盆冷水下来，报如下错误：

o.s.a.r.l.SimpleMessageListenerContainer : Failed to check/redeclare auto-delete queue(s).

起先以为是配置错误，确认配置没问题后，百度一下，发现是给用户授予了角色，只能登录控制台，但是没有给读写以及管理队列的权限，通过控制台admin按钮查看

通过命令授权

语法： set_permissions [-p <vhostpath>] <user> <conf> <write> <read>

执行： rabbitmqctl set permissions -p / admin .* .* .* 完成对admin的授权,然后启动项目就正常了

真实示例，楼主成功试验： rabbitmqctl set_permissions -p / lzj ".*" ".*" ".*"

rabbitmqctl set_permissions -p /vhost_db0 logan "^logan-.*" ".*" ".*"
