mysqlまたはmongodbをgrailsに統合する方法3.2.10

Question

私はWebアプリケーションプロジェクトを開始しています.MysqlをGrails 3に統合しようとしています。すべてのオンラインチュートリアルでは、現在（Application.ymlがあります）。

私はApplication.ymlを公式ドキュメントに記載されているように変更しようとしましたが、大きなエラーが出ます。その新しいプロジェクトであり、それに他の変更はありません。私は以前にgrails 2.4を使っていましたが、それは本当に簡単でしたが、今、私は戻ってくることを考えています。

変更：私が得る

Answer 1

問題は、あなたのデータソースにMAXAGE値を設定しようとしている方法である：

タイプ 'java.lang.String'のプロパティ値を に変換するのに失敗しました。プロパティ 'maxAge'に 'long'が必要です。ネストされた例外は java.lang.NumberFormatExceptionです：入力文字列の場合：「10 * 60000」

だけで計算するのではなく、具体的な値を設定してみてください。

Answer 2

もしあなたがYML標準に慣れていないなら、単にapplication.groovyという名前の新しいファイルを作成し、それをconfディレクトリの中に置き、そのgroovyファイルにデータソースブロックを追加してください。 application.ymlファイルからデータソースブロックを削除することを忘れないでください。
