"BeanDefinitionStoreException: Failed to process import candidates for configuration class" 将 JHipster 单体应用程序部署到 Heroku 时
"BeanDefinitionStoreException: Failed to process import candidates for configuration class" when deploying a JHipster monolithic app to Heroku
我以前从未部署过任何类型的 JVM Web 应用程序，所以我真的不知道发生了什么。从 Heroku 日志中，错误看起来如下：
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [tld.domain.webapp.FinancialServicesStationApp]; nested exception is java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$EmbeddedDatabaseConfiguration**
我使用 MariaDB 作为我的数据库，Gradle 用于构建，后端是用 kotlin 编写的。我使用了在我自己的机器上编译源代码的选项，我认为这应该有效，因为我可以 运行 开发模式下的站点就好了。有人知道导致此错误的原因以及我该如何解决吗？

错误的重要部分是：
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'JDBC_DATABASE_URL' in value "${JDBC_DATABASE_URL}"
Heroku 部署无法将数据库属性注入您的应用程序上下文，因此无法启动。
所以，也许您没有订阅 jawsdb 插件或者您没有注册付款方式。在 Whosebug
上几乎没有类似的问题
我想您是按照文档中的描述使用 jhipster heroku 部署的：https://www.jhipster.tech/heroku/
我以前从未部署过任何类型的 JVM Web 应用程序，所以我真的不知道发生了什么。从 Heroku 日志中，错误看起来如下：
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [tld.domain.webapp.FinancialServicesStationApp]; nested exception is java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$EmbeddedDatabaseConfiguration**
