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 or change the port number(s).

eclipse运行web时出现上述报错，这是由于你已经在外面通过starup.bat打开了tomcat,而在eclipse中运行时会再一次通过server打开Tomcat，这就造成了上面端口被占用的发中生，解决方法就是找到Tomcat的文件夹下bin文件夹然后双击shutdown.bat关闭Tomcat后再在eclipse中运行即可。
