「IllegalArgumentException：[EJBインターフェイス]フィールド[マネージドBeanフィールド]をcom.sun.proxy。$ Proxy [いくつかの番号]に設定できません」OmniFacesの@Eager

debugcn 投稿 Dev

カール・リヒター

マルチモジュールのMavenJava EE 7プロジェクトでJSFマネージドBeanにEJBを挿入すると、Payara 4.xと5.x、Glassfish 4.xと5.x、WildFly11.0.0.Finalの両方で失敗します。最初に思ったように、これはPayara / Glassfishのバグではないと思います[1]。

WARモジュールの単純なJSFバッキングBean

@Named
@ApplicationScoped
@Eager
public class Init {
    @EJB
    private InitService initService;

    public Init() {
    }

    @PostConstruct
    public void init() {
        initService.init();
    }
}

JARモジュールのEJBインターフェースを使用

@Local
public interface InitService {

    void init();
}

およびEJBモジュールでの実装

@Stateless
public class DefaultInitService implements InitService {
    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public void init() {
        Long id = 1L;
        MyEntity myEntity0 = entityManager.find(MyEntity.class, id);
        if(myEntity0 == null) {
            myEntity0 = new MyEntity(Long.MIN_VALUE, "myProperty");
            entityManager.persist(myEntity0);
        }
    }
}

Payara4.1.2.174で失敗する

これは先行していますが、PrimeFacesでOmniFaces @Eagerアノテーションを使用する方法と同じではありませんか？その質問では、ロギングが正しく構成された後でも、例外やその他のフィードバックは得られなかったためです。

プレーンなDockerイメージで問題を再現するサンプルプロジェクトとGitLabCI出力は、参照されている問題から簡単に見つけることができます（異なるブランチの異なるASと対応するCIパイプラインセクションの出力）

[1] https://github.com/payara/Payara/issues/2237およびhttps://github.com/javaee/glassfish/issues/22401で報告されており、プロキシクラスのキャスト例外に関連する例がさらに少なくなっています。まあ、しかしスタックに関与する溶接はありませんでした。

カール・リヒター

...Proxyクラスキャスト例外の問題はMavenの起因compileWEBモジュール内（WEBとEJBモジュールを含むEJBの実装に次のエンティティとEJBインターフェースを含む）JARモジュールのスコープ。これにより、EJBインターフェイスクラスが異なるクラスローダーによってロードされ（このJava EEセットアップでは正しい）、クラスローダーの動作の定義によって異なるクラスと見なされます。

この問題は、スコープをprovidedWEBモジュール内に変更することで問題なく回避できます。

アプリケーションサーバー（GlassFishとWildFly、そしておそらく他のサーバー）のフィードバックは、多くの（Java EE）テクノロジーと同様にひどいものであり、改善を提案しましたが、アプリケーションが正しく機能する場合は20作業の％であり、考えられるすべての状況で有用なフィードバックを得るには、残りの80％を処理する必要があります。実現するには、ある程度の時間（数十年）がかかります。
