org.springframework.beans.factory.BeanCurrentlyInCreationException:「sessionFactory」という名前のBeanの作成中にエラーが発生しました

誰かが解決策を持っていますか、なぜ私のsessionFactory Beanがエラーを出しているのですか?

前もって感謝します...

Springは問題が何であるかを正確に伝えています。ログとネストされたエラーメッセージを読むだけです。

Beanプロパティ 'sessionFactory'の設定中に、Bean'sessionFactory 'への参照を解決できません。ネストされた例外はorg.springframework.beans.factory.BeanCurrentlyInCreationExceptionです: 'sessionFactory'という名前のBeanの作成中にエラーが発生しました:現在作成中のFactoryBeanがgetObjectからnullを返しました

Googleで少し検索すると、このエラーメッセージは通常 循環依存 の結果であり、 推奨するメーリングリストの投稿 からdefault-autowire="detect"を削除することになります。 <beans>要素。
