一、Tomcat异常：Several ports (8005, 8080, 8009) required by Tomcat v8.5 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).

这表示端口被占用了，我们首先要检查所使用的端口是否有被占用的情况
最简单的就是打开任务管理器查看

发现正在运行的javaw.ee，将其关闭就可以了

此时，服务已经可以正常运行
