win查看所有端口和PID

应用启动失败时端口被占用的排查:netstat 查端口 PID、taskkill 杀进程。

控制台最后会显示Application启动失败,如下:

...
 
***************************
APPLICATION FAILED TO START
***************************
 
Description:
 
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
 
...
  1. 打开cmd命令窗口  输入如下指令查看所有端口和PID
netstat -ano

2. 找到对应的端口对应的PID ,输入指令找到对应的进程

tasklist | findstr "4044"

3.杀掉该进程,再次启动就OK啦

taskkill /f /t /im java.exe
