在服務器上安裝了一個RabbitMq,并新創建了一個用戶授予了管理員角色，登錄控制臺查看一切正常，興高采烈啟動項目進行連接，結果一盆冷水下來，報如下錯誤：

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

起先以為是配置錯誤，確認配置沒問題后，百度一下，發現是給用戶授予了角色，只能登錄控制臺，但是沒有給讀寫以及管理隊列的權限，通過控制臺admin按鈕查看

通過命令授權

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

執行： rabbitmqctl set_permissions -p / admin .* .* .* 完成對admin的授權,然后啟動項目就正常了
