而且我可以确认应用程序的某些部分 运行 没问题，例如某些 restful json 端点（它们响应正确 json 数据）
但是任何 JSP 页面呈现都死了...错误日志如下所示：

所以我认为这与 java 8 env 问题有关？但是在 heroku 上，我相信 tomcat 版本默认为 9 https://devcenter.heroku.com/changelog-items/1724
但是我不知道如何使用 heroku cli 实际检查我的 tomcat 版本，有人知道吗？
或者看起来像 heroku tomcat 问题？如果是这样，我应该使用哪个版本的 tomcat？
请指教
谢谢
能否请您尝试将 web-runner 依赖项升级到 9.0.27.1？目前设置为，

所以我认为这与 java 8 env 问题有关？但是在 heroku 上，我相信 tomcat 版本默认为 9 https://devcenter.heroku.com/changelog-items/1724 但是我不知道如何使用 heroku cli 实际检查我的 tomcat 版本，有人知道吗？
或者看起来像 heroku tomcat 问题？如果是这样，我应该使用哪个版本的 tomcat？ 请指教 谢谢
能否请您尝试将 web-runner 依赖项升级到 9.0.27.1？目前设置为，
