SpringブートServiceバインディング付きPCFへのアプリケーションのデプロイ

Question

PCF経由で単純なアプリケーションをPivotal Webサービスにデプロイしようとしましたが、postgresqlまたはmysqlサービスのようなサービスをバインドするとアプリケーションがクラッシュします。

これらのコネクタは、あなたのVCAP_SERVICES環境変数を検査し、DataSource豆を作成するために、春のランタイムで使用することができますServiceInfoオブジェクトを作成します：あなたのコードを見た後、私はあなたのPOMに次と再び試みる追加することをお勧め。
