SpringServletContainerInitializer 在 tomcat 8.0 上给出 Unsupported major.minor 版本 52.0 问题

Question

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

Jenkins 在 AWS 上构建，并将战争部署到 AWS 上的应用服务器。我安装了一个 docker 并使用 tomcat v8.0 映像创建了一个容器。 sudo docker run -d --name tomcat-container -p 8080:8080 tomcat:8.0

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

        <springfox-version>2.9.2</springfox-version>
    </properties>

请告知可能出了什么问题。我无法使用当前版本的 tomcat，因为我的应用程序无法在其上运行。

Answer 1

感谢@PiotrPKarwasz 的建议。我使用了 tomcat v9 docker 容器，我能够克服这个问题。我没有这个问题了。
