我已经使用带有 React 前端的 springboot 构建了一个 Web 应用程序，当我在本地运行该应用程序时，我可以毫无问题地使用我的 REST API 调用。一旦我将所有内容打包成一个 war 文件并将其部署到我的 VM 上的 tomcat 服务器上，我就无法再访问我的后端了。
catalina.out 日志文件中没有出现错误，但也没有 springboot 应用程序启动的迹象。这就是我得到的全部。

在发帖之前，我已经解决这个问题两天了，但没有效果，我实现了 servletInitializer，因为我最初没有。我通过服务器访问前端没有问题，只是无法进行任何 API 调用。
这是我第一次尝试将网络应用程序部署到服务器，因此非常感谢任何帮助/建议。如果需要更多信息我可以提供！
