***************************
APPLICATION FAILED TO START
***************************

Description:

The Tomcat connector configured to listen on port 8097 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8097, or configure this application to listen on another port.

运行java调试时一直不成功，一看时端口号8097被占用了，一脸懵逼，问了一下度娘。总结如下方法

解决办法

1.打开cmd命令窗口 输入指令查看所有端口和PID

netstat -ano

2.找到对应的端口对应的PID 输入指令找到对应的进程

tasklist | findstr "7620"

3.杀掉该进程

 taskkill /f /t /im java.exe

4.再次重新启动程序就可以了
