如何在Heroku上運行Spring MVC應用程序？

我在IDEA中的tomcat 7.0.72上運行的Spring MVC上有簡單的應用程序。我如何在Heroku上運行這個應用程序（如果可能的話）。我有Heroku帳戶，我確實在其上創建了應用程序。我使用Maven進行部署，並使用Gi​​t將其推送到Heroku中。應用程序的文件將在下面。所以，當我通過tomcat在localhost上運行它時，它就可以工作。但是，當我推在Heroku我明白了：如何在Heroku上運行Spring MVC應用程序？

我看到了，並試圖做到這一點。但應用程序錯誤。並在其中指導應用程序以不同的方式/類型寫。 – Dmitry

它在日誌中顯示什麼？ –

有（至少）爲Java的Web兩種部署方式應用：

第一個在這裏詳細描述：

https://devcenter.heroku.com/articles/create-a-java-web-application-using-embedded-tomcat

第二個在這裏詳細描述：

https://devcenter.heroku.com/articles/java-webapp-runner

你似乎有兩種機制的混合元素在你的POM：例如web應用的領先者只在第二種樣式中需要。

刪除這些衝突並檢查配置。

那麼，我無法創建可以在IDEA中通過tomcat和heroku運行的應用程序？ – Dmitry

我嘗試以第二種方式做到這一點。 – Dmitry

您可以從IDEA進行部署：https：//devcenter.heroku.com/articles/deploying-java-applications-to-heroku-from-eclipse-or-intellij-idea或閱讀spring boot in action chapter 8 –
