问题描述

我刚刚下载了这个项目:

I just downloaded this project:

https://github.com/oktadeveloper/okta-spring-boot-2-angular-5-example

在本教程中解释:

https://developer.okta.com/blog/2017/12/04/basic-crud-angular-and-spring-boot

但是当我尝试使用推荐的命令运行服务器时:

But when I try to run the server with the recommended command:

./mvnw spring-boot:run

我得到以下输出:

如您所见，有一行是这样写的:

As you can see, there is one line that says:

The Tomcat connector configured to listen on port 8080 failed to start.

知道如何让服务器工作吗?

Any idea on how to make the server work?

谢谢！

推荐答案

它说BindException: Address already in use: bind"，你一定已经在 8080 端口下运行了某个应用程序.尝试终止该服务器并重新启动，或为此应用程序使用不同的端口，例如 8081.如果您无法检查哪个应用程序已经在使用端口 8080，请使用以下命令

It says "BindException: Address already in use: bind", you must already be running some application under port 8080. Try to terminate that server and start again, or use a different port for this application, like 8081. If you can't check which app is using port 8080 already, use the following command

netstat -anob

假设您使用的是 Windows，您现在可以通过任务管理器检查并终止应用程序.

You can now check and kill the application through task manager, assuming you're on windows.

这篇关于配置为监听 8080 端口的 Tomcat 连接器启动失败的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
