私の春のアプリケーションのためにJUnitテストを書いています。私はこれが初めてなので、動作することがわかっているDAOクラスの単体テストを作成することから始めてみました(JBossで実行しました)。ただし、Eclipseでユニットテストとして機能させることはできません。「Beanの作成中にエラーが発生しました...フィールドを自動配線できませんでした:NoSuchBeanDefinition 」が表示され続けます。
StackOverflowや他のサイトでこれに似たエラーが発生しましたが、常に構文エラーであるか、インターフェイスではなくインターフェイスの実装を自動配線しようとしました。コードにこれらのエラーは表示されません。
プロジェクトに付属のSpring構成とは別にSpring-test.jarをダウンロードしました。どちらもSpring2.5のものなので、問題になるとは思いません:/
EclipseにはJUnit4.8がバンドルされていますが、Spring Unit Testはそれで動作しないため、JUnitを4.4を使用するようにダウングレードしました。
考慮すべきことが1つあります...単体テストのコードを見ると、2つのフィールドが自動配線されていることがわかります。テストしたいクエリサービスのSimpleJdbcTemplateです。さて、DrugDaoとそれへのすべての参照を削除すると、SimpleJdbcQueryは問題なく自動配線されます。
レビューのスタックトレースは次のとおりです。
