Javaリフレクションを使用してSpring Beanを呼び出す

Question

静的に動的に動的にSpringを呼び出すことはできません。

私は動的にBeanを呼び出すために以下に従いましたが、以下のエラーが発生しています。

org.springframework.beans.factory.NoSuchBeanDefinitionException：

ソースコードという名前の豆：

1。メインサービスクラス

@Component 
public class ContentService 
{ 
    @Autowired 
    private ApplicationContext _appContext; 

    public void process() 
    { 
     try { 
       Object bean = _appContext.getBean("com.content.partner.Movie"); 
       Method method = bean.getClass().getMethod("parseContents"); 
       method.invoke(bean); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
    } 
} 

2。映画サービスクラス

@Component 
public class Movie 
{ 
       private static final Logger _log = LoggerFactory.getLogger(Movie.class); 

    @Autowired 
    private Environment _env; 

    public void parseContents() 
    { 
      _log.info("enter into parsecontents"); 
    } 
} 

エラー：私が理解、あなただけに

Object bean = _appContext.getBean("com.content.partner.Movie");

を変更する必要があるから

Answer 1

Object bean = _appContext.getBean("movie");

これらすべての「コンポーネント」を既にスキャンしている場合に限ります。
