大家好，又见面了，我是你们的朋友全栈君。
CMD查看端口占用情况，8080端口被TIM占用了
安装新版本dubboAdmin的时候，启动后端项目dubbo-admin-server报一下错误：

APPLICATION FAILED TO START

Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port报错原因是8080端口被占用了 cmd查看所有端口使用情况
代码语言：javascript复制netstat-anocmd查看8080端口使用情况
代码语言：javascript复制netstat -ano |findstr 8080结果如下，可以找到占用8080端口的进程的pid
任务管理器下查看，发现端口是被Tim占用了
结束TIM进程即可
