Several ports (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).
解决办法：
不用重启电脑
windows+r cmd
输入 netstat -ano|findstr 8080 //说明：查看占用8080端口的进程
输入 taskkill /pid 6856 /f //说明，运行windows自带taskkill命令，将上面显示的进程号，结束掉。
