当我第一次在localhost中运行应用程序时，它可以工作。但是我更改代码并重新运行，它显示了这个错误消息。终止所有进程并重新运行时。再次显示下面的消息。

但是我换了服务器。应用程序属性中的端口。它的工作原理。但我试着再运行一次，我得到了以上的错误。当我一直运行时，我应该想要更改application.properties中的服务器端口。有解决这个问题的办法吗?

用于tomcat 8006的端口已被使用。您需要终止该进程并重新运行项目

在cmd上使用此命令获取进程的PID号:

netstat -ano | findstr :8006

然后使用以下命令终止该进程:

taskkill /PID <PID> /F
