heroku webapp runner发动战争的麻烦

我正试图使用Heroku教程中的说明来启动一场非常简单的造波战争：

本教程使用以下java语法运行war： $java-jar target/dependency/webapp-runner.jar target/*.war

当我部署到Heroku或在本地运行此命令时，我也会遇到同样的错误行为。页面打开时显示一个永不停止旋转的计时器。应用程序永远不会启动

我本来会发布一个屏幕截图，但我显然没有足够的“堆栈溢出点”。：（。这有一个附件有屏幕截图

有什么想法可以纠正这个问题吗？

你说得对，问题不是Heroku；它很可能是由您的构建（包括servlet api jar）引起的。看看，它应该可以帮助您解决问题
