Java SpringServletContainerInitializer在tomcat 8.0上给出了不支持的主要版本52.0和次要版本52.0问题

我正在构建一个应用程序，使用Jenkins从git构建代码，并将其部署到tomcat服务器映像。以下是我的配置：

Jenkins build在AWS上，将war部署到AWS上的应用服务器。我安装了一个docker，并使用TomcatV8.0映像创建了一个容器。

sudo-docker-run-d——命名tomcat容器-p 8080:8080 tomcat:8.0

当我启动容器并尝试访问应用程序http://：/application时，我收到一个错误。下面是我看到的

请就可能出现的问题提出建议。我无法使用tomcat的当前版本，因为我的应用程序无法在该版本上运行。

谢谢@PiotrPKarwasz的建议。我使用了tomcat v9 docker容器，我能够克服这个问题。我不再有这个问题了。

这是否回答了您的问题？基本上，问题不在于Tomcat的版本（尽管2018年以来不支持8.0），而在于Java的版本（自2015年以来不支持Java 7），这对于您的Spring库来说太旧了。
