在Eclipse中运行Web项目Jsp网页时提示端口被占用的解决办法：Several ports (8005, 8888, 8009) required by Tomcat v9.0 Server at localhost are already in use.

问题：

在Eclipse中运行Web项目Jsp网页启动Tomcat时提示端口被占用：

　　Several ports (8005, 8080, 8009) required by Tomcat v9.0 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：

　　在Windows操作系统中运行输入cmd

(1)输入命令netstat -ano|findstr "8080"，查看8080端口是否被占用，且得到了进程号“3084”；如果输入上述命令后再DOS窗口未出现任何信息提示，则表明所查询的端口未被占用。
(2)再输入命令tasklist|findstr "3084"，得到进程映像名javaw.exe；
(3)启动任务管理器，结束javaw.exe进程；
(4)最后再输入命令netstat -ano|findstr "8080"，查看8080端口是否被还占用
