Error 场景

启动 Java 项目失败，控制台显示

***************************
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.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

解决方法

• 查看那些进程占用了我们的端口号8080

  打开 Windows 控制台，输入命令

netstat -nao | findstr "8080"

可以看到占用 8080 端口的进程 PID 为 8404

• 杀死相应进程：

  在 Windows 控制台，继续输入命令

taskkill /pid 8404 /f
