@Stateful Beanを別の@Stateful Beanに挿入する

Question

glassfish 3.1サーバーでは、別のステートフルセッションBeanに注入される@StatefulセッションBeanがあります。

注入されたステートフルセッションBeanは、自分のエンティティアクセスレイヤーを表示します。それ自体は@PersistenceContextでエンティティマネージャーが挿入されており、このように見えます。

@Stateful 
MyEAO { 
    @PersistenceContext 
    EntityManager em; 

    MyEAO() { 
     // default constructor 
    } 

    .... 
} 

このアクセス層は、他のステートフルBeanに注入されています

@Stateful 
public class ShopAdmin implements ShopAdminInterface { 
    @EJB MyEAO; 

    .... 
} 

これは働いていました！ - 今すぐ、別のコンストラクタをMyEAOに追加するとすぐに、2番目のBeanにMyEAOを注入すると例外が発生します。

奇妙なことは、両方の豆が以前はセッション豆の@Statelessだったことです。全く問題はありませんでした。

私は2番目のコンストラクタを使用して、glassfishコンテナの外で動作するJUnitテストのエンティティマネージャを渡しました。

ショート：「無国籍時代」では、すべてが期待通りに機能しました！

私はEJBについて非常に新しかったので、ここで何が欠けていますか？ここで

Answer 1

私はあなたがあなたのクラスの明示的な引数なしのコンストラクタを持っていないと思われます。

IMOテストのフィールドを に設定する必要があるため、Beanクラスに特別なコンストラクタを追加するのは良い解決策ではありません。あなたのための多くのトリックを行うことができるいくつかの素晴らしいツールがあります。 http://unitils.org/cookbook.html - > JPA DAOをテストしてください。これは必要なものです。
