经常出现这种问题。。。。。。

Several ports (8005, 8080, 8009) required by Tomcat v6.0 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).

    在eclipse非正常关闭或者没关闭掉tomcat情况下，虽然eclipse关掉了，但是Tomcat服务器没有关。若重新使用eclipse会出现上述错误。这种状况解决方法把占用的端口关掉就可以了。

打开windows 任务管理器，强制关闭所有的javaw.exe ,重新打开Eclipse 就可以了。

tomcat端口冲突
