依存関係の見つかりません：この依存関係の自動配線候補として適格な少なくとも1つのBeanが必要です。依存関係の注釈：

Springを使用してSOAPサービスを記述しようとしていますが、Dependency Injectionの問題が発生します。私はこのようなサービスで@Autowiredを使用して問題が発生しています：

    public interface UserDao {
    User getUser(String username);
}

以下のようなDaoの実装：

  @Controller("userDao")
    public class UserDaoImpl implements UserDao {
    private static Log log = LogFactory.getLog(UserDaoImpl.class);

    @Autowired
    @Qualifier("sessionFactory")
    private LocalSessionFactoryBean sessionFactory;

    @Override
    public User getUser(String username) {
        Session session = sessionFactory.getObject().openSession();
        // Criteria query = session.createCriteria(Student.class);
        Query query = session
                .createQuery("from User where username = :username");
        query.setParameter("username", username);
        try {
            System.out.println("\n Load Student by ID query is running...");
            /*
             * query.add(Restrictions.like("id", "%" + id + "%",
             * MatchMode.ANYWHERE)); return (Student) query.list();
             */
            return (User) query.uniqueResult();
        } catch (Exception e) {
            // TODO: handle exception
            log.info(e.toString());
        } finally {
            session.close();
        }
        return null;
    }

}

そして

public interface UserBo {
    User loadUser(String username);
}

そして

public class UserBoImpl implements UserBo {
    @Autowired
    private UserDao userDao;

    @Override
    public User loadUser(String username) {
        // TODO Auto-generated method stub
        return userDao.getUser(username);
    }

}


@WebService
@Component
public class UserService {

    @Autowired
    private UserBo userBo;

    @WebMethod(operationName = "say")
    public String sayHello(String name) {
        return ("Hello Java to " + name);
    }

    @WebMethod(operationName = "getUser")
    public User getUser(String username) {
        return userBo.loadUser(username);
    }
}

例外を見てください：

No qualifying bean of type [edu.Java.spring.ws.dao.UserDao] found for dependency

これは、その依存関係を満たすBeanがないことを意味します。はい、インターフェースの実装はありますが、その実装用のBeanを作成していません。次の2つのオプションがあります。

  • UserDaoImplに@Componentまたは@Repositoryで注釈を付け、UserServiceで行ったとおりにコンポーネントスキャンに作業を任せます。
  • UserBoImplで行ったのと同じように、Beanを手動でxmlファイルに追加します。

Beanを明示的に作成する場合は、コンポーネントスキャンの前に定義を配置する必要があることに注意してください。この場合、順序は重要です。

注釈@RepositoryをUserDaoImplの実装に追加します

@Repository
public class UserDaoImpl implements UserDao {
    private static Log log = LogFactory.getLog(UserDaoImpl.class);

    @Autowired
    @Qualifier("sessionFactory")
    private LocalSessionFactoryBean sessionFactory;

    //...

}

Implクラスの前に@Serviceを追加しましたが、エラーはなくなりました。

@Service
public class FCSPAnalysisImpl implements FCSPAnalysis
{}

私の場合、@DataJpaTest注釈を追加するため、アプリケーションコンテキストは読み込まれません。 @SpringBootTestに変更すると機能します。

@DataJpaTestは、Spring BootアプリケーションのJPA部分のみをロードします。 JavaDocで：

一般的なJPAテストで@RunWith(SpringRunner.class)と組み合わせて使用​​できる注釈。テストがJPAコンポーネントにのみをフォーカスしている場合に使用できます。この注釈を使用すると、完全な自動構成が無効になり、代わりにJPAテストに関連する構成のみが適用されます。

デフォルトでは、@DataJpaTestアノテーションが付けられたテストは、埋め込みインメモリデータベースを使用します（明示的または通常自動構成されたDataSourceを置き換えます）。 @AutoConfigureTestDatabase注釈を使用して、これらの設定をオーバーライドできます。完全なアプリケーション構成をロードしたいが、埋め込みデータベースを使用する場合は、このアノテーションではなく、@SpringBootTestと組み合わせた@AutoConfigureTestDatabaseを検討する必要があります。

インターフェイスUserDaoの実装が欠落しているようです。例外をよく見ると、

依存関係のタイプ[edu.Java.spring.ws.dao.UserDao]の修飾Beanは見つかりませんでした。

@Autowiredが機能する方法は、インターフェイスを介して注入する依存関係の実装を自動的に検索することです。この場合、UserDaoインターフェースの有効な実装がないため、エラーが発生します。このクラスの有効な実装があり、エラーが発生することを確認してください。

お役に立てば幸いです。

この問題に直面していますが、別の理由がありました。ここに理由があります：

このプロジェクトでは、同じBean名を持つ複数のBeanエントリが見つかりました。 applicationcontext.xmlに1つ＆dispatcherServlet.xmlに1つ

例：

<bean name="dataService" class="com.app.DataServiceImpl">
<bean name="dataService" class="com.app.DataServiceController">

＆我々はdataService名で自動配線しようとしています。

解決策： Bean名を変更し、解決しました。

私の場合、@Serviceアノテーションをインターフェイスから実装クラスに移動する必要がありました。

DAO実装クラスの前にリポジトリアノテーションを追加します。例：

@Repository
public class EmpDAOImpl extends BaseNamedParameterJdbcDaoSupportUAM 
implements EmpDAO{ 
}

追加するのを逃した

@Controller("userBo") into UserBoImpl class.

これに対する解決策は、このコントローラーをImplクラスに追加することです。
