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).

1、在dos下，输入  netstat   -ano|findstr  8080

//说明：查看占用8080端口的进程，显示占用端口的进程

2、taskkill  /pid  1952  /f

//说明，运行windows自带taskkill命令，将上面显示的进程号，结束掉。

搞定
