org.springframework.beans.factory.wiring.BeanWiringInfo.BeanWiringInfo가 null 이름으로 초기화되었습니다.

Question

스프링 세션과 Aspectj를 사용하여 세션 직렬화 후 Redis로 @Autowired 필드를 다시 연결하려고합니다.

@UIScope() 
@SpringComponent(value = AboutView.VIEW_NAME) 
@SpringView(name = AboutView.VIEW_NAME)  
// 
@Configurable(autowire = Autowire.BY_NAME, value = AboutView.VIEW_NAME, dependencyCheck = false, preConstruction = true) 
public class AboutView extends AbstractView { 

    public static final String VIEW_NAME = "butterfly-effect-frontend-system:about"; 

    private Table tableFrontEndInformation; 

    private GridLayout backendLayout; 

    private GridLayout frontendLayout; 

    @Autowired 
    private transient DiscoveryClient discoveryClient; 

이 빈은 @Configurable과 빈 정의 (값)의 이름을 사용하고 있습니다 :

이

는 빈입니다. 불행하게도 aspect는 null bean 이름을 가진 BeanWiringInfo을 생성하고있다. 이것은 이름이 필요하기 때문에 에러를 발생시킬 것이다.

:이 오류가

protected BeanWiringInfo buildWiringInfo(Object beanInstance, Configurable annotation) { 
     if (!Autowire.NO.equals(annotation.autowire())) { 
      return new BeanWiringInfo(annotation.autowire().value(), annotation.dependencyCheck()); 
     } 
     else { 
      if (!"".equals(annotation.value())) { 
       // explicitly specified bean name 
       return new BeanWiringInfo(annotation.value(), false); 
      } 
      else { 
       // default bean name 
       return new BeanWiringInfo(getDefaultBeanName(beanInstance), true); 
      } 
     } 
    } 

:

@Configurable(autowire = Autowire.BY_NAME, value = AboutView.VIEW_NAME, dependencyCheck = false, preConstruction = true)

누구든지이 구성에서 무엇이 잘못 될 수 있는지 알고 있습니까?

귀하의 도움에 감사드립니다.

Answer 1

아직 이해가 안되지만 @Configuration에서 autowire = Autowire.BY_NAME을 제거하는 것이 문제를 해결하는 것 같습니다.

이제 클래스는 다음과 같습니다

@UIScope() 
@SpringComponent(value = AboutView.VIEW_NAME) 
@SpringView(name = AboutView.VIEW_NAME) 

// 
@Configurable(value = AboutView.VIEW_NAME) 
public class AboutView extends AbstractView {
