Caused by: java.net.BindException: Address already in use: bind

##场景 Idea开启多个springboot程序后

##看到 Caused by: java.net.BindException: Address already in use: bind 知道端口占用引起的

##解决方案(windows下)

     #查询出8080端口被那些进程占用着
    netstat -ano | findstr 8080
    #关闭进程
    tasklist | findstr <进程号>
    #强制关闭
    taskkill -PID <进程号> -F
