autowired依存関係の注入に失敗しました。

Question

私は小さなJava EEにHibernate、Springアプリケーションとエラーを開発していますが登場：

package com.bd.controleur; 

    import java.util.HashMap; 
    import java.util.Map; 

    import org.springframework.beans.factory.annotation.Autowired; 
    import org.springframework.stereotype.Controller; 
    import org.springframework.web.bind.annotation.RequestMapping; 
    import org.springframework.web.servlet.ModelAndView; 

    import com.bd.service.ArticleService; 

    @Controller 
    @RequestMapping("/Article/GererArticle") 
    public class ArticleControleur { 

    @Autowired 
    ArticleService articleService; 

    public ModelAndView listarticle() { 

    Map<String, Object> model = new HashMap<String, Object>(); 
    model.put("articles", articleService.getAllArticles()); 

    // new ModelAndView("nom de la page jsp", model qui contient l'ensemble 
    // des beans que tu vas passer a cette page) 
    return new ModelAndView("GererArticle", model); 

    } 

    }

そして、ここでは、記事のリストを回復するための機能が含まれている私のコントローラArticleControleurです

これは私の記事ですサービス：

そしてここに私のアプリケーションコンテキストがあります：

Answer 1

このエラーは、com.bd.service.ArticleServiceが登録済みのBeanではないことを示しています。サイドノートとして

<context:component-scan base-package="com.bd"> 
    <context:include-filter type="aspectj" expression="com.bd.*" /> 
</context:component-scan> 

、あなたの場合：あなたはcom.bd内のすべてのサブパッケージを含めたい場合は、

<context:component-scan base-package="com.bd.service"/> 
<context:component-scan base-package="com.bd.controleur"/> 

また：あなたのアプリケーションコンテキストにautowiredされる豆を持っているパッケージを追加します。 Spring 3.1以降を使用している場合は、@ComponentScanアノテーションを利用できるため、コンポーネントスキャンに関するxml構成を使用する必要はありません。 @Configurationと組み合わせて使用​​してください。

@Controller 
@RequestMapping("/Article/GererArticle") 
@Configuration 
@ComponentScan("com.bd.service") // No need to include component-scan in xml 
public class ArticleControleur { 

    @Autowired 
    ArticleService articleService; 
    ... 
} 

Autowiringのこの春の奥行きセクションが便利でしょう。

Answer 2

idが "articleService"のコンテキストファイルで宣言されたBeanはありますか？ autowireは、あなたのコンテキストファイル内のBeanのidと、Autowireにしようとしている変数名とを一致させると信じています。
