问题

启动javar报错，提示如下

Description:

解决方案

1. 调出命令终端
   win+r 并且输入cmd

2. 查看某个端口(8080)的被占用情况

netstat -ano |findstr 8080

显示

C:\Users\gusijin>netstat -ano |findstr 8080
  TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       17244
  TCP    192.168.10.122:60391   14.116.242.250:8080    ESTABLISHED     14908
  TCP    [::]:8080              [::]:0                 LISTENING       17244

  TCP    [::1]:8080             [::1]:55342            TIME_WAIT       0

C:\Users\gusijin>taskkill -PID 14908 -F
成功: 已终止 PID 为 14908 的进程。

3. 根据进程号(14908)关闭进程即可

taskkill -PID 14908-F 

tasklist | findstr 17244
显示
java.exe 17244 Console 3 188,908 K

杀掉该进程 再次启动就OK啦

taskkill /f /t /im java.exe
