1、问题描述
项目启动的时候报:
org.apache.catalina.LifecycleException: Protocol handler start failed at
2、问题原因
端口在系统已经被占用了,启动会报这个错误
3、问题解决
方案一:
修改端口,本人觉得大部分程序员都不太愿意修改端口(我个人以为哈【手动调皮】),除非是一些应用占了不得不改一下
方案二:
Windows+R >cmd
netstat -ano,列出所有端口的情况
netstat -aon|findstr “8081”, 最后一位数字,即PID
tasklist|findstr “9088”, 进程或者程序占用了9088端口
kill 端口
