前言

IDEA 突然崩溃后重启项目，报错

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2020-09-30 16:10:15.312 ERROR 2712 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

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

Description:

Web server failed to start. Port 8091 was already in use.

Action:

Identify and stop the process that's listening on port 8091 or configure this application to listen on another port.


Process finished with exit code 1

原因

其中这句话写的很清楚，端口被占用，因为着急启动，选择换了个端口
Web server failed to start. Port 8091 was already in use.

解决

这里解决的是关闭之前的端口，因为还想用
访问我以前接口还是可以访问通，但是idea没有这个项目

通过CMD的命令窗口 netstat -a -n
可以清楚的看到已运行的端口

如何关闭这个进程？
使用命令netstat -nao | findstr 8091

看到PID后执行

taskkill /pid 7960 /F

复查端口，发现已经关闭
