如图所示，Tomcat 服务器似乎在正确的端口上运行，没有明显错误。但是，在我的 Chrome 搜索栏中输入 http://localhost:8080/（正确的输入地址）后，我会收到一个错误屏幕，其中包含以下消息：

此页面不工作

localhost 没有发送任何数据。

ERR_EMPTY_RESPONSE

该站点使用 H2 内存数据库，通常可以通过导航到 http://localhost:8080/h2-console 来访问该数据库，但这不起作用并产生相同的错误。

之后我尝试在端口 8080 上运行另一个应用程序，并且能够确认端口 8080 确实被我的初始 webapp 使用，因为第二个应用程序没有运行并产生错误。

假设源 GitHub 项目没有任何问题（我可以自信地声称没有），我做错了什么导致这个问题，如何解决？
