Spring Tomcat未重定向到index.html

出于某种原因，我部署到tomcat中的spring boot war没有为index.html中的站点根请求提供服务。（index.html位于上下文根目录下）

当我使用一个可执行的war时，一切正常-自动加载index.html。出于某种原因，当我将同一个war部署到tomcat并导航到时，我得到了SpringBoot的404页面。不过，这很好。我在可执行war和tomcat日志的启动日志中看到了“o.s.b.a.w.s.WelcomePageHandlerMapping:Adding welcome page:ServletContext resource[/index.html]”。然而，在tomcat的访问日志中，有一个404，没有重定向：

GET/HTTP/2.0“404286

My web.xml具有以下内容，似乎在任何地方都不会被覆盖

Tomcat（404）
