Tomcat端口被占用是个老问题了，时不时就会出现，今天又遇到了，就简单记录一下这个问题的解决方式。
启动项目报错
Several ports (8005, 8080, 8009) required by Tomcat v8.0 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).
首先 win + R ，键入cmd ,再Enter
输入 netstat -ano|findstr 8080 查看8080端口的占用情况
netstat -ano|findstr 8080
再使用 taskkill /pid 9172 /f 杀掉进程即可
taskkill /pid 9172 /f
即可正常启动
