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.
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 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。
