netstat -ano | findStr [端口号]

查看某个端口被哪个进程占用
netstat -ano | findStr 2436

  TCP    127.0.0.1:2436         127.0.0.1:9999         ESTABLISHED     22588
  TCP    127.0.0.1:9999         127.0.0.1:2436         ESTABLISHED     12308

这里pid为22588的进程和pid为12308建立了本地tcp连接,分别占用了端口2436和9999,第四列是tcp的状态,参考https://www.cnblogs.com/jessezeng/p/5617105.html
