***************************
APPLICATION FAILED TO START
***************************

Description:

The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.
 

 一開始沒發現問題在哪裡，就在網上找了下對應的異常類解決方法。網上的部落格都是說少了jar包。但是我這個明顯不是jar包導致的，後來懷疑是埠被佔用。換了埠號為8080，重啟專案。BUG依然存在。

後來仔細檢視日誌，發現一個IP

 感覺有問題啊，馬上檢視下本機IP 這不是我的IP地址啊。 問題大概知道了。一看springBoot的配置檔案

server.address=172.30.200.50
server.port=8080

 不知道那個哥們吧這個配置提交上GIT了。然後我這邊拉取下來就這樣。啟動springboot的時候他去把專案繫結到這個IP上。但是IP又不存在。直接導致這個異常的發生

解決方法 註釋掉這個配置server.address=172.30.200.50
