Spring + Spring Data + Hibernate機能を備えた単純なJARを作成しようとしています。これは、SpringまたはHibernate + JPAを区切りにしたときに機能しますが、すべてをまとめているときは機能しません。Spring + SpringデータJava SE JPAスタンドアロン
このタイプの設定は可能ですか？
私はMavenアセンブリプラグインを使用して依存関係のあるJARを作成しています。
JPAエンティティをスキャンする具体的なパッケージも示していますが、これはEclipseで動作しますが、単一のJARを実行すると動作しません。
私の構成はXMLフリーです（persistence.xmlまたはapplication.xmlはありません）。これでpersistence.xmlが検索されます。 META-INF/persisntece.xmlにファイルを置くと、エラーは同じです。

私はSpring Bootを使用して実行可能なjarファイルを作成し、頭痛を軽減することをお勧めします。関係なく、あなたの 'ConfigPersistence'を質問に追加できますか？ –
私はSpringBootを検討していますが、私の現在の環境にとっては重すぎると思います。メモリのパフォーマンスを考慮して、SpringBootでスタンドアロンのアプリケーションの例がありますか？ – crm86
それはなぜでしょうか？ブートを実行しているコマンドラインアプリケーションと、実行しているコマンドラインアプリケーションが異なる理由Spring Bootは、Tomcatやその他のものを持っている必要があるということを意味するわけではありません。普通のコマンドラインの場合は、これを使うことができます。違いはありません。ここでの主な問題は、変更されたjarファイルにクラスパスのトリックがいくつかあることです。これは、春の読み込みには不公平なので、いくつかのトリッキーが必要です。また、メモリとパフォーマンスについての仮定を行うのではなく、実行できることは1つだけあり、それは自分のためのテストです！ –
