スタックトレースからコピー:
BeanInstantiationException:Beanクラスをインスタンス化できませんでした[com.gestEtu.project.model.dao.CompteDAOHib]:デフォルトのコンストラクターが見つかりません。ネストされた例外はJava.lang.NoSuchMethodExceptionです:com.gestEtu.project.model.dao.CompteDAOHib。<init>()
デフォルトでは、Springはデフォルト(引数なし)コンストラクターを呼び出してBeanのインスタンス化を試みます。あなたの場合の問題は、CompteDAOHib
の実装にSessionFactory
引数を持つコンストラクタがあることです。 @Autowired
注釈をコンストラクターに追加することにより、Springは一致するタイプのBean、あなたの場合はSessionFactory
を見つけようとし、コンストラクター引数として提供します。
@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
// ...
}
同様のエラーが発生していますが、皆さんと共有したいだけです。多分それは誰かを助けるでしょう。
EntityManagerFactory
を使用してEntityManager

プロジェクトをきれいにして再構築してください。
org.springframework.beans.factory.BeanCreationException:「MyController」という名前のBeanの作成エラー
ライブラリにojdbc14.jar
を追加したことを確認してください。
ここではOracle11g
を使用していますが、ojdbc14.jar
はありません。私に何ができる?
@Controllerから@ServiceにCompteControllerに変更し、@ ServiceアノテーションをCompteDAOHibに追加します。それでもこの問題に直面している場合はお知らせください。
例外は問題を明確に示しています。
CompteDAOHib: No default constructor found
SpringがBeanをインスタンス化するには、クラスCompteDAOHib
に空のコンストラクターを提供する必要があります。
必要な注釈をすべて追加しても何も起こらない場合は、この依存関係をpom.xml
に追加してみてください。同じ問題に直面したため、ここに追加して解決しました。
