springboot启动失败，8080端口被占用

mac下启动springboot失败，8080端口被占用，mac命令行关闭端口

如下图，idea启动springboot失败，8080端口被占用

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

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

Description:

Web server failed to start. Port 8080 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.

第一步：打开mac终端，或者idea的终端
输入: lsof -i:8080 (lsof -i:端口号)

查看进程可以看到我的端口对应的进程id是1472，那么kill这个进程即可

COMMAND  PID        USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
java    1472 test  120u  IPv6 0x71c9463ce2ac6f49      0t0  TCP *:intu-ec-svcdisc (LISTEN)

第二步：mac下关闭进程，使用kill命令

kill 1472

关闭进程后重新运行SpringBoot,就可以正常运行了。

如果有一同学习java的同学可以加我qq裙：636984730，一起交流。
