Spring项目端口占用

Description:

Web server failed to start. Port 8080 was already in use.

Action:

Identify and stop the process that's listening on port 8080 or configure this application to listen on another port.

分析：错误信息“Web server failed to start. Port 8080 was already in use.”意味着您的Spring Boot应用程序试图在端口8080上启动，但是该端口已经被另一个进程占用了。 

//解决：在demo项目中找到application.properties文件，添加别的端口号，例如
server.port=8081
