在部署heroku應用程序後創建jpa存儲庫時出錯

無法在部署後運行應用程序。添加了clearDB插件並相應地修改了數據庫網址，用戶名和密碼。

連接從SQL工作臺Heroku的cleardb和創建的表成功，但我仍然得到錯誤：

我在heroku中使用spring 1.4.3版本。我不確定這是Heroku支持的正確版本。可能是什麼問題？

Answer 1

首先，立即重置您的數據庫憑據（因爲您已經在互聯網上公開發布了它們）。你必須參考ClearDB documentation的說明。

然後use the JDBC_DATABASE_URL而不是硬編碼您的連接參數。你可以把這個在你的代碼：

dataSource.setUrl(System.getenv("JDBC_DATABASE_URL"); 

如果這仍然給你的問題，嘗試JawsDB add-on代替（它似乎有少的問題）。
