前言
上一篇博客講述了ubuntu 16.04上如何安裝RabbitMq，并通過web管理界面遠程訪問。
緊接著我在自己搭建的spring boot項目中，整合了RabbitMq，本地啟動項目，發現控制臺一直報錯。。。

項目啟動報錯
org.springframework.amqp.AmqpIOException: java.io.IOException….

具體報錯如下截圖：

問題分析
其實在我上一家公司，開發過程中，本地啟動項目也會一直報這個錯！！

首先，我確定rabbitmq正常啟動了，可以遠程訪問，且項目中配置文件是正確的：

# ?rabbitmq:
# ? ?host: 127.0.0.1
# ? ?port: 5672
# ? ?virtual-host: /
# ? ?username: guest # 默認的guest用戶
# ? ?password: guest
? rabbitmq:
? ? ? host: 132.232.54.106 ? # 服務器IP
? ? ? port: 5672 ? ?# 端口
? ? ? virtual-host: /
? ? ? username: demo ? #新增用戶名
? ? ? password: demo

將rabbitmq主機改為127.0.0.1，username：guest。然后將項目打成war包，放到安裝rabbitmq的服務器上面運行。
啟動成功后，本地瀏覽器訪問項目swagger接口，并調用測試接口，查看日志，是ok的。

經過一番百度，最終得到的解決辦法：
將rabbitmq新增的用戶授權就可以了。具體解決辦法如下：

操作步驟：
1.打開RabbitMq web管理界面，進入該頁面，點擊用戶名稱

2.點擊 set premission 按鈕，就ok了

over，這個時候再去本地啟動一下項目，使用這個用戶。。是不是發現就沒報錯了。QAQ
最后說一下，rabbitmq的這個可視化工具還是挺好用的。
