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

二、原因

  • Tomcat 的默认8080端口被占用

三、解决方法

  • cmd输入netstat -ano|findstr 8080,找到占用8080端口的进程
  • 列对应的分别是:协议-本地地址-外部地址-状态-PID
  • 输入taskkill /f /pid PID终止8080端口进程,此例PID为5476,故输入taskkill /f /pid 5476

  • 或者打开任务管理器,找到PID为5476的进程将其结束

  • 重新Spring-boot启动Run,一直转圈但未报出SEVERE: Failed异常,表示Tomcat是正常运行的,打开浏览器输入访问地址即可
