java - WAR 文件已部署，但在尝试获取数据时响应 404

Question

在 Tomcat 10 上，当部署 war 文件时，tomcat 会进行部署，但在访问它时说资源不可用，并以 404 状态代码响应。Tomcat 日志说没有找到该 jar 的 TLD。我能够运行war文件java -jar ./Game-0.0.1-SNAPSHOT.war并在浏览器中访问它。

环境：运行 CentOS、Tomcat 10、Java 11。

我已将依赖项和打包添加到我的 pom.xml 中，并编辑了主类。

pom.xml：

我尝试过手动部署，并通过 tomcat manager gui 进行部署，这是显示在 tomcat manager gui 中部署的 war 文件的屏幕截图。 雄猫管理器
