私はSpringとJavaの世界にまったく慣れていません。サンプルで提供されているペットクリニック アプリケーションを参照して、Web アプリを作成しようとしています。しかし、昨日からこの障害にぶつかっています。誰かが私を正しい方向に向けることができれば、それは素晴らしいことです. Googleで多くのリンクを調べましたが、解決策はどれもうまくいきませんでした.

ここにエラーの根本原因があります

org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

これがWEB-INFの私のweb.xmlです

<display-name>Game's List</display-name>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/applicationContext-hibernate.xml</param-value>
</context-param>

<session-config>
    <session-timeout>10</session-timeout>

</servlet>

<servlet-mapping>
    <servlet-name>gamelist</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

これがapplicationContext-hibernate.xmlです

これは gamelist-servlet.xml です

<context:component-scan base-package="com.gamelist"/>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/pages/"/>
    <property name="suffix" value=".jsp"/>
</bean>

これはコントローラークラスです

    public class GameLibraryController {

    private IDataStore gameDataStore;

    @Autowired
    public GameLibraryController(GameItemDataStore gameDataStore){
        this.gameDataStore = gameDataStore;
    }

    @RequestMapping("/addGame")
    public String addNewGame(Model model){
        model.addAttribute("gameItem",new GameItem());
        return "library/addgameform";
    }

    @RequestMapping("/addGameSubmit")
    public void add(@ModelAttribute GameItem gameItem,BindingResult result, SessionStatus status){
        this.gameDataStore.add(gameItem);
        status.setComplete();
    }
}

これは休止状態の実装クラス GameItemDataStore です

  @Repository
    @Transactional
    public class GameItemDataStore implements IDataStore{
    private SessionFactory sessionFactory;

    @Autowired
    public GameItemDataStore(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    public void add(BaseItem newGame){
        sessionFactory.getCurrentSession().save(newGame);
    }
}

これは IDataStore インターフェイスです

 public interface IDataStore {

    public void add(BaseItem newGame);
}

取り除く

<bean id="gameDataStore" class="com.gamelist.datastore.GameItemDataStore"/>

@Repositoryあなたのクラスのため、あなたは必要ありません

<context:annotation-config />

あなたは二度持っています。それから加えて

<context:component-scan base-package="com.your.package" />

クラスをcom.your.package含む最上位パッケージですGameItemDataStore。
