Heroku SprinBoot Deployment is sucess but Status is 503 Service Unavailable
您好，我正在尝试将 Spring 启动应用程序部署到 Heroku。构建成功，但当我尝试 运行 应用程序时，出现 Status 503: Service Unavailable 错误。
我提到了类似的 post

我遇到了同样的问题！对于我的情况，最简单的解决方案是只使用 Java 1.8 项目 - Heroku 自动默认为 1.8。
根据Java Heroku文档here，支持的版本如下：
- Java 7 -
1.7.0_312
- Java 8 -
1.8.0_302
- Java 11 -
11.0.12
- Java 13 -
13.0.8
- Java 15 -
15.0.4
- Java 16 -
16.0.2
您似乎正在使用 Java 11. 要将此告诉 Heroku，请在您的资源文件夹中创建一个名为 system.properties 的文件。在 system.properties 中添加 java.runtime.version=11。我相信你也可以做到 java.runtime.version=11.0.12.
希望对您有所帮助！查看文档以获取更多信息。
事实证明，失败日志提到 Heroku 需要 Procfile 和 Spring 引导应用程序。
摘自 Spring 文档：
要自定义 Heroku 构建，我们需要提供一个 Procfile，它提供部署应用程序所需的指令。 Heroku 分配一个端口供 Java 应用程序使用，然后确保到外部 URI 的路由有效。
我们必须配置我们的应用程序以侦听正确的端口。这是入门 REST 应用程序的 Procfile：
web: java -Dserver.port=$PORT -jar target/demo-0.0.1-SNAPSHOT.jar
