我刚开始学习一些Spring，我尝试创建一个简单的CRUD应用程序。完成一些教程后，我的应用程序无法构建。我在代码中做了一些重大更改，所以最终我删除了工作区中的所有内容，并使用Spring Project Starter创建了一个新项目。仅运行启动项目我在控制台中收到此错误：

这种情况一直在继续，但我不能在这里发布单一帖子。如果您有任何想法如何帮助我，请告诉我需要什么，我将为您提供错误代码等。
谢谢
答案 0 :(得分：0)
地址已在使用中。我认为你必须在重新运行项目之前先停止运行项目的服务器。
或单击自动停止并重新启动服务器的重新启动按钮。然后您可能不会再次出现此错误。
这是因为使用了已经在使用的相同服务器端口。（例如tomcat：8080）。要停止服务器 - 单击控制台面板中的红色按钮。
答案 1 :(得分：0)
您已经拥有占用端口8080的内容，这可能是由于您在删除工作区中的所有内容时运行服务而导致的。
查看您的系统进程（如果在Windows上，则按ctrl + shift + esc），查看您是否正在运行java进程并将其终止。它应该是javaw.exe。一旦该过程停止，您将能够重新启动服务器。
