报错：Several ports (8005, 8080, 8009) required by Tomcat v7.0 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).
解决办法：
ctrl+shift+esc打开任务管理器找到java.exe进程关闭，启动tomcat就行了。
