二：項目使用總結，先來一個坑,測試環境沒問題，到了線上出問題，報下面的錯：

RabbitMQ異常注意 reply-code=404, reply-text=NOT_FOUND - no exchange 'topic' in vhost '/', class-id=50, method-id=

Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=404, reply-text=NOT_FOUND - no queue 'album.free.topaid.transcode.success..queue' in vhost '/', class-id=50, method-id=20)

1.看到這個報錯，第一想到的是，應該是queue沒有創建，一般測試環境都是設置的默認自動創建，仿真和線上是運維人員創建，那就找運維人員確認下，是不是創建了，創建的類型對不對，對下queue的名稱，type類型是fanout還是topic，確認幾個屬性，auto-declare="true" auto-delete="false" durable="true" exclusive="false"是否一致，一般auto-declare="true"是不配置的，其他是默認的，確認了這些都沒問題，陷入坑裏了，什麼原因那；

2.會不會是創建好的queue被服務再次重申覆蓋，或者聲明的有問題；這時候想到declared-by="admin"這個屬性，在有多個admin的情況下exchange以及queue都需要聲明是哪個管理的，原因找到了，測試和仿真沒有問題是因爲這兩個環境，多個admin地址都是同一個，線上卻是多個，在有多個地址的時候，不能確認是哪個admin管理的。

3.可能報403，406，530等，這些可以根據報錯直接看出問題，比如

530：connection error; protocol method: #method<connection.close>(reply-code=530, reply-text=NOT_ALLOWED - access to vhost '/' refused for user 'kumas', class-id=10, method-id=40)

說明：賬戶kumas沒有對 “/” 的權限，在 mq 管理頁面上添加權限即可

406：com.rabbitmq.client.AlreadyClosedException: channel is already closed due to channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'test_data' in vhost '/': received 'true' but current is 'false', class-id=50, method-id=10

翻譯過來就是exchange的durable已經true了不能改爲false。所以使用的時候要注意如果exchange和queue的durable已經定義好了是不能更改的。除非客戶端刪掉exchange，queue然後重新啓動。
