GlassFish にデプロイする単純なテストアプリケーションがあります (1 つの単純なクラスが注入された 1 つのリソースのみ)。GlassFish では、すべて正常に動作しています (FINE をログに記録するときの例外を除きます。ここを参照してください)。リソースを正常に呼び出すことができ、Weld CDI が注入を行っています。
Java SE でアプリケーションを起動して JUnit で単体テストを実行すると、HK2 がインジェクションを提供しようとしているように見え、それが UnsatisfiedDependencyException につながります。
InjectMe クラスをバインドする AbtractBinder を定義して、HK2 が認識できるようにします。その後、注射はうまくいきます。ただし、Weld CDI は、クラスを HK2 ではなく、Jersey リソースに挿入する必要があります。
ブートストラップは、カスタム JUnit ランナー (WeldJUnit4Runner) とアノテーションを作成することによって行われます@RunWith(WeldJUnit4Runner.class)。
Weld CDI は Java SE 環境で正常にブートストラップされ、Jersey リソースではなく、実際の JUnit テストクラスに InjectMe クラスを正常に挿入できます。InjectMe クラスは、Weld ブートストラップによって検出されます。
2014-07-16 10:41:12,730 [DEBUG] org.jboss.weld.Bootstrap - WELD-000106: Bean: Managed Bean [class com.test.rest.InjectMe] with qualifiers [@Any @Default]
質問: Java SE で実行しているときに、HK2 が Weld ではなく InjectMe クラスを注入しようとするのはなぜですか?
編集: Netbeans プロジェクトを作成したので、このテストを簡単に再現できます: simple-service.zip。java ロギングのプロパティを logging.properties ファイルに設定することを忘れないでください。
java.util.logging.config.file=C:\glassfish4\glassfish\domains\domain1\config\logging.properties
これは、Netbeans の「テスト ファイル」アクション用に定義することで実現しました。プロパティ ファイルで、次のフラグを定義する必要があります。
org.glassfish.jersey.level=FINEST
昨日テストしていたとき、この正確なセットアップが実際に機能する時がありましたが、それらの例外はありませんでした. HK2が最初に初期化されることがある静的初期化に問題があると思いますが、これがこのエラーにつながると思います。
