[eclipse] Several ports (8005, 8009) required by ...问题

在写一个java web程序时，每次打开eclipse都会报出下面的问题：

Several ports (8005, 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).

查了一下网上，应该是端口被占用，可以到severs文件中去改端口，也可以在任务管理器中结束javaw.exe,然后再点击运行就可以运行程序了。
