启动项目报错：The Tomcat connector configured to listen on port 8080 failed to start.

启动SpringBoot项目，报错：

org.apache.catalina.LifecycleException: Failed to start component [Connector[HTTP/1.1-8080]]
    ....
 
Caused by: org.apache.catalina.LifecycleException: Protocol handler start failed
    ....
 
Caused by: java.net.BindException: Address already in use: bind
    ....

错误描述：

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.

意思就是说8080端口一直被占用着，从而无法启动项目。此时很懵啊，因为本地并没有其他项目跑着…

解决：

1. cmd打开黑窗口，输入下面指令显示所有端口和PID进程ID

   netstat -ano
   

2. 找到8080端口对应的PID，通过tasklist指令找到对应的进程

   tasklist | findstr "7676"
   

3. 通过杀死此进程

   taskkill /f /t /im java.exe
