Spring、埋め込みDerby-Jetty自動再デプロイDB接続問題を持つHibernate

私は、ダービーDbを埋め込んだ春の休止状態のアプリケーションを実行し、自動再デプロイメントを使用してそれをjetty上で実行しています。今すぐ自動再デプロイを行う上で、私は、DB接続エラーが発生します：Spring、埋め込みDerby-Jetty自動再デプロイDB接続問題を持つHibernate

あなたの問題については、以下の記事を見てください。http://stackoverflow.com/questions/24491328/stopping-tomcat-doesnt-delete-derby-db-lck – shankarsh15

@ shankarsh15これは彼らの言うことです：最初の問題：組み込みデータベースとしてDerbyを使用する場合、データベースは最初の接続時に起動されますが、明示的にシャットダウンする必要があります。そうでない場合は、db.lockファイルは削除されず、アプリケーションを再起動すると問題が発生する可能性があります。 Tomcatや（デフォルトでは）春にはこのようなデータベースを自動的にシャットダウンするものはありません...しかし、その解決策は何ですか？ – Harinder

Harのinder、

私はあなたがいくつかのコードを編集する必要があると思います。
