'Starting Tomcat v9.0 Server at localhost' has encountered a problem. Port 8080 required by Tomcat v9.0 Server at localhost is 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). 解决方法

查找占用端口号8080的命令：netstat -aon|findstr “8080”

然后去任务管理器，把相关的PID关闭即可。
