私はこの問題をかなり前から取り組んでおり、動作させることはできません。あなたの何人かが私を助けるためにあなたの時間を惜しまないことを願ってくださいSpringデータリポジトリの自動ワイヤリングが失敗します
シナリオ
私はSpring MVCを使用するWebアプリケーションを構築しています。このWebアプリケーションは、永続レイヤを含む別のMavenプロジェクトを使用することになっています。現在、パーシスタンス層はサービスとSpring Dataリポジトリのみで構成されています。持続層自体は、ローカルのMySQLインスタンスに対して動作します。
私の問題
私は、永続層のためのJUnitテストを持っています。テストはエンティティをロードして保存します。これはサービス上で処理されます。どちらの操作も正常に動作します。
私はwebappのMavenプロジェクト内のJUnitテストでこれを試しています。私はエンティティを保存して読み込もうとしています。しかし今回は失敗します。 Springは、サービス内のリポジトリ参照がautowiredにならず、適合するbeanが存在しないことを示しています。
私はこれを解決するために複数のアプローチを試みました。たとえば、直接配線を使用して、修飾子などを与えます。私のアプローチのどれも働かなかった。私はシナリオを簡略化した2つの完全なMavenプロジェクトを新たに構築しましたが、必要な要素は同じままにしました。そこには魅力のように働いた。私は実際の設定からの設定を適用したので、私が何を間違っているのか分かりません。

インタフェースQuestionRepositoryの実装は何ですか？ –
'QuestionRepository'の実装はありません。バネデータの魔法を使って、必要なリポジトリのBeanを作成します。インターフェースを '@ Repository'に注釈を付けて、そのパッケージを'
Okはそれを知らなかった:)そしてなぜ' QuestionService'が 'QuestionRepository'インターフェースから継承するのか。これは 'QuestionServiceImpl'によって実装されているため、ある種の循環依存性に遭遇することがあります。 –
