解决关于The Tomcat connector configured to listen on port 9100 failed to start.

The Tomcat connector configured to listen on port 9100 failed to start. The port may already be in use or the connector may be misconfigured.在springcloud学习编译经常会出现的问题。

错误提示：

Description:

The Tomcat connector configured to listen on port 9100 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 9100, or configure this application to listen on another port.

Process finished with exit code 1

出现原因：端口号被占用。

解决方法：

1、同时按win+R，弹出命令窗口，输入cmd，如图所示：

 

2、输入指令：netstat -ano

3、找到所需端口对应的PID

 输入指令找到对应的进程

tasklist | findstr " 16228"

4、输出：taskkill /f /t /im java.exe，杀死该进程

End：这样这个端口号就可以用了。
