您可能在本地使用 Java 17，但在 Heroku 上您使用的是 Java 8。 This is the default :

Heroku currently uses OpenJDK 8 to run your application by default. Other OpenJDK versions are also available. Depending on the OpenJDK version you select the latest available version of that JDK will be used each time you deploy your app.

您需要explicitly request the correct version of Java 。将名为 system.properties 的文件添加到项目的根目录，其中包含

java.runtime.version=17

然后提交并重新部署。
