jhipster

Question

使用 jhipster 生成器后，我能够使用本地 PostgresQL 在本地网络服务器上成功运行应用程序。我也设法将它部署到 Heroku，但是现在当我尝试在 IntelliJ 中本地运行它时（就像我在部署之前所做的那样），（选择 'dev profile'，单击 spring-boot :运行) 或运行应用程序主方法，
我收到以下错误（未配置 Heroku 数据库 url）：

请原谅我的问题..这是设计使然还是我遗漏了一些步骤？

Answer 1

从日志的第一行来看，Heroku 数据库URL 未配置

Caused by: org.springframework.context.ApplicationContextException: Heroku database URL is not configured, you must set --spring.datasource.heroku-url=$DATABASE_URL 希望以下示例对您有所帮助：

https://github.com/jhipster/generator-jhipster/blob/master/heroku/templates/src/main/java/package/config/_HerokuDatabaseConfiguration.java

Answer 2

因为this error，已经在最新版本修复了

jhipster - 在将应用程序部署到 Heroku 后无法运行本地开发配置文件

jhipster - can't run local dev profile after deploying app to Heroku

postgresql

heroku

intellij-idea

spring-boot
