6月19日浑吟，需要修改一個BUG扼脐，打開IDEA? debug起來 竿痰，一直報錯苟弛。
查看日志：View-Tool Windows-EventLog
16:43 Error running 'tomcat9': Address localhost:1099 is already in use
16:43 Error running 'tomcat9': Unable to open debugger port (127.0.0.1:5521): java.net.SocketException "Socket closed"
嘗試了各種修改JVM端口褪测，重啟IDE猴誊，依然無效.
最后查看tomat日志：
19-Jun-2019 16:41:59.098 嚴重 [main] org.apache.catalina.core.StandardServer.await Failed to create server shutdown socket on address [localhost] and port [8005] (base port [8005] and offset [0])

Can't assign requested address (Bind failed)！Ｎ甏搿Ｐ柑尽！分扎！
最后解決的方法是澄成，在本機添加一個host:
127.0.0.1 localhost?
