【问题描述】：

我已经使用 PostgreSQL 数据库创建了 Spring Boot Gradle 应用程序并部署在 heroku 上

应用程序部署在 heroku 上，此 URL https://lawcase.herokuapp.com，我在我的 Spring Boot 应用程序中开发了 Rest API， 我还添加了 ProcFile

web: java -jar build/libs/LawCase-0.0.1-SNAPSHOT-plain.jar

但是当我尝试使用带有 Postman 的 URL 访问 API 时

 https://lawcase.herokuapp.com/getprofiles

我收到 503 服务不可用

这里是heroku日志

我尝试过***的不同解决方案

Heroku jar deployment of Spring Boot with Maven Application giving code=H10

Heroku error code H10 when Spring Boot app is deployed

Spring Boot on Heroku - H10 "app crash"

How can resolve 503 (Service Unavailable) after GET/POST on Spring Boot and Heroku?

heroku[web.1]: State changed from starting to crashed

但是我无法解决我的问题并且我的应用程序无法运行，谁能帮助我在 Heroku 上正确部署和升级我的应用程序。

【参考方案1】：

回答是因为我无法发表评论。几个想法。 Spring Boot 应用程序可能不需要 Procfile，因为有一个内置的 Web 服务器（除非你想覆盖某些东西）。还发现了 this 类似的情况，这是一个 postgres 驱动程序问题。
