私は と が初めてspring mvcですhibernate。理解しやすくするために、このチュートリアルhttp://viralpatel.net/blogs/spring3-mvc-hibernate-maven-tutorial-eclipse-example/に従い ました。このエラー org.hibernate.HibernateException: No Session found for current thread が発生しています。サービスの実装と dao にトランザクション マネージャーと @transaction を含めました。以下のエラーとコード スニペットを見つけてください

spring 構成ファイルでこの行のコメントを解除すると、機能するはずです。これがないと @Transactional アノテーションは無視されます。最初に持っているタグは mvc 名前空間 (あなたの場合はデフォルトの名前空間) からのものです - その目的はこれとは異なります。したがって、両方を持っている必要があります。
