JSF/Spring/JPA/Hibernateアプリケーションのtype = PersistenceContextType.EXTENDEDとjavax.persistence.OptimisticLockExceptionの間の競合

Question

純粋なJSF/Hibernate WebアプリケーションをJSF/Spring 3.0/Hibernate/JPAアプリケーションに移植しようとしています。 依存性注入を使用して、DAOクラスにEntityManagerのインスタンスを挿入します。 @PersistenceContext注釈でtype = PersistenceContextType.EXTENDED属性を使用すると、 状態はブラウザ間で共有され、ログインページは表示されません。私は最近、と呼ばれるものを知った私は、EXTENDEDを指定いけない場合、私は最初の更新の後に私のレコードを更新することができませんちょうどJSF - session scoped bean shared by browsers on different machines のように異なるブラウザだけでなく、異なるウィンドウ を試してみましたが、javax.persistence.OptimisticLockException

を取得しますスコープを表示しますが、それが解決策であるかどうかはわかりません。両方の目的を達成する方法を提案してください a。後続の更新時にOptimisticLockExceptionを避ける b。

おかげ サーガルR. Kapadia

私の設定とソースファイルブラウザ間で共有状態を避ける

Answer 1

は永続コンテキストがするまで閉じられないことを意味しますあなたは明示的にクローそれを見てください。 DatabaseはシングルトンBeanであるため、EntityManagerはBeanが実行する限り（永遠に）存続します。そのため、実際にはEXTENDEDシナリオで作成されたトランザクションマネージャは1つだけなので、すべてのスレッドで同じトランザクションマネージャが表示されます。

エンティティマネージャ（永続コンテキスト）は、トランザクションだけでなくリクエストの間オープンされたままになるように、「ビュー内のオープンエンティティマネージャ」パターンが必要です。たとえば、OpenEntityManagerInViewFilterを見てください。
