    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
