java - Spring 3.1プロジェクトをhibernate4に更新し、現在のスレッドでセッションが見つからないようになりました

Question

SpringWebFlowプロジェクトをSpring3.1に更新する必要があり、Hibernate4はMavenを機能させるために更新しました。すべてが正常に機能しているように見えますが、データベースの読み取りを実行するプロジェクトの一部で、次のエラーが発生します。

org.hibernate.HibernateException: No Session found for current thread   org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97)

hibernate3でこのエラーが発生しなかった理由はわかりませんが、誰かがこれを修正する方法を教えてください。

これが私のpom.xmlです

これをサービスに追加してみてください：

これは SpringSessionContext.java からスローされた例外です。hibernate3.SessionHolder を使用するとインスタンスから識別できないため、この問題が発生する前に、このコードをデバッグして変数値に何が起こったかを確認できます。これは役に立つかもしれません。

遅延読み込みの問題のようです。OpenSessionFactoryInViewFilter または OpenSessionFactoryInViewInterceptor を有効にしましたか? トランザクション内で実行されるコードはこの例外を受け取るべきではありませんが、ビューのレンダリングは通常、フィルター/インターセプターを必要とするトランザクションの外部で発生します。コードを見ないとなんとも言えません。
