本文介绍了解决SpringBoot应用启动时遇到的8080端口被占用问题的方法。通过使用cmd命令检查端口占用情况，找到PID为5260的进程，并使用taskkill命令终止该进程，最终成功启动应用。

The port may already be in use or the connector may be misconfigured.

启动spring boot时发现此错误，原来是8080端口被占用了
cmd查看一下占用端口的进程：

netstat -aon|findstr 8080
在这里插入图片描述
可以看出占用端口的是PID为5260的进程，终止这个进程即可
taskkill /f /t /im 5260
![在这里插入图片描述](https://img-blog.csdnimg.cn/20190816112821550.png
再次查看端口

至此，启动正常
补充:
如拒绝访问，如图

可启动任务管理器，在详细信息列，根据对应PID线束对应进程

确定要放弃本次机会？
