私はSpringブートアプリケーションを開発中で、サーバ起動時にこのエラーが発生しました。注釈が間違って定義されているか、依存関係がないかはわかりません。どんな助けもありがとう。Springブート - リポジトリフィールドに 'entityManagerFactory'という名前のBeanが見つかりませんでした。

Description:
Field leagueRepository in com.dheeraj.service.LeagueService required a bean named 'entityManagerFactory' that could not be found.
Action:
Consider defining a bean named 'entityManagerFactory' in your configuration.
あなたはJPAの自動設定を実行していないようです。スターターとデータベース接続があることを確認してください。 – chrylis
@chrylis - JPAの自動設定を実行するにはどうすればよいですか？私はapplication.propertiesにmysqlデータベースへの接続を確立しました – Dheeraj
あなたはHibernateの依存関係が不一致です。バージョン番号を削除し、Bootでそれらを管理させるだけです。 – chrylis
