Several ports (8005, 8080, 8009) required by Tomcat v8.5 Server at localhost are already in use.

Several ports (8005, 8080, 8009) required by Tomcat v8.5 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：

1 运行cmd->netstat -avo，

找出占据了8005, 8080, 8009端口的PID

2 任务管理器

找出该PID的任务，右键->结束任务

3 回到Eclipse，重新Start
