Tomcat出现异常：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
大意为：端口被占用

解决方法：
方法一（推荐）：

方法二：在本地tomcat的解压缩文件下找到/conf/server.xml，把8005, 8080, 8009三个端口号全部修改为（三个随意的端口号）。
