mac啓動springboot失敗，8080端口被佔用，mac命令行關閉端口

以下圖，idea啓動springboot失敗，8080端口被佔用

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2018-05-23 22:18:43.688 ERROR 3793 --- [  restartedMain] o.s.b.d.LoggingFailureAnalysisReporter   : 

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

Description:

Web server failed to start. Port 8020 was already in use.

Action:

Identify and stop the process that's listening on port 8020 or configure this application to listen on another port.

mac下怎麼使用命令行關閉端口呢？

打開mac終端，或者idea的終端，輸入:

lsof -i:端口號（個人是8020，那麼輸入以下命令）
lsof -i:8020

輸入 lsof -i:8020 後回車

bogon:it399_springboot chenshouyin$ lsof -i:8020
COMMAND  PID        USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
java    1472 chenshouyin  120u  IPv6 0x71c9463ce2ac6f49      0t0  TCP *:intu-ec-svcdisc (LISTEN)
bogon:it399_springboot chenshouyin$

能夠看到個人端口對應的進程id是1472，那麼kill這個進程便可

mac下關閉進程

kill 進程id，上面個人進程id是1472，那麼直接輸入以下命令便可

kill 1472

關閉佔用端口的進程以後，再啓動springboot再也不報錯了
