记录java.net.BindException: Address already in use: bind及如何查看端口占用

on 2017-12-27 | by ancongcong 关注作者

这个问题很常见，解决起来也不难，就是你想要开启的端口被占用了,那么如何排查是哪个进程占用了呢？比如看windows下80端口被哪个程序占用，Linux下80端口被那个程序占用。

windows下查看80端口占用

直接打开cmd，执行netstat -ano | findstr "80"，最后一栏是进程ID：

netstat -ano | findstr "80"

可以通过tasklist | findstr 1324 找到是哪个任务在使用

tasklist | findstr 1324
httpd.exe                     1324 Services                   0      4,084 K

taskkill可以终止PID

taskkill /pid 1324 /F
成功: 已终止 PID 为 1324 的进程。
