在 Heroku 上部署 Spring 引导应用程序 - 构建成功，但随后：无法提供页面
[英]Deploying Spring Boot App on Heroku - Build Success, but then: page could not be served
问题描述
The spring boot app / server works locally when I start it in IntelliJ or in the cli with $ java -jar demo-0.0.1-SNAPSHOT.jar , and the heroku build is also successful, but when I go to the url it says Application Error 。 关于为什么 heroku 没有显示我的网站的任何想法？
我已经完成了在其他 stackoverflow 问题中找到的提示（ Heroku cannot deploy Java 11 Spring Boot App ）：
1. 我确保 java 版本相同：
在我的 pom.xml 文件中：
<?xml version="1.0" encoding="UTF-8"?>

我在根目录中创建了一个 Procfile，其中包含：
web: java -jar 目标/demo-0.0.1-SNAPSHOT.jar
我检查了 SDK 设置为 11：
- 我检查了 Java 编译器设置为 11：
此外，这是我的 maven 版本：
这些是我的路径系统变量：
And all of this is actually also on my git hub: https://github.com/gkromer/test2 Here is the link to my app from heroku: https://nameless-chamber-03761.herokuapp.com/
我还通过 heroku 的入门页面上的简单演示对其进行了测试。 效果很好，没问题。 因此，我认为问题出在我的 IntelliJ 或 Maven 中，因为对于 heroku 的示例，我不需要它（示例中的所有内容都可以使用 CLI 完成）。 信息：我的 spring 应用程序中没有数据库。
当我运行时：
这是我的 heroku 日志尾部：
$ heroku logs --tail

你快到了，
Heroku 测功机公开了一个动态端口供您的应用程序绑定。 此值在
$PORTenvvar中公开。
您可以在日志中看到它8080 8090 ...
所以更新你的Procfile以绑定到这个端口，如下所示：
web: java -Dserver.port=$PORT $JAVA_OPTS -jar target/demo-0.0.1-SNAPSHOT.jar
