해결법

==============================
1.비 JSF 개발자를위한 순진한 솔루션은 getter 내부의 변수를 초기화하여 속성의 null 값을 해결하는 것입니다. 이것은:

비 JSF 개발자를위한 순진한 솔루션은 getter 내부의 변수를 초기화하여 속성의 null 값을 해결하는 것입니다. 이것은:
```
public List getListeAnnees() {
    listeAnnees = getAnneeMetier().getAllAnnees();
    return listeAnnees;
}

public AnneeMetier getAnneeMetier() {
    if (anneeMetier == null) {
        anneeMetier = new AnneeMetierImpl();
    }
    return anneeMetier;
}
```
하지만 AnneeMetier # getAllAnnees ()가 데이터베이스에서 데이터를 검색하는 경우 서버로부터 많은 오버 헤드가 발생할 수 있습니다. 여기서는 JSF가 getter를 여러 번 호출하는 이유에 대해 설명합니다.

이를 해결하기 위해 다음 두 가지 작업을 수행합니다.

그리고이 결과는 다음과 같습니다.

따라서 코드는 다음과 같습니다.
```
@ManagedBean
@ViewScoped
public class AnneeBean {
    private AnneeMetier anneeMetier;
    private List<Annee> listeAnnees;

    @PostConstruct
    public void init() {
        anneeMetier = new AnneeMetierImpl();
        listeAnnees = anneeMetier.getAllAnnees();
    }

    public List getListeAnnees() {
        return listeAnnees;
    }

    public void setListeAnnees(List listeAnnees) {
        this.listeAnnees = listeAnnees;
    }

    public AnneeMetier getAnneeMetier() {
        return anneeMetier;
    }

    public void setAnneeMetier(AnneeMetier anneeMetier) {
        this.anneeMetier = anneeMetier;
    }
}
```
그러나 JSF를 Spring과 통합하려고하기 때문에 Spring이 아직 JSF 2 @ViewScoped 주석을 완전히 지원하지 않는다는 점을 고려해야한다. 이 경우 사용자가 직접 구현해야합니다. 이것에 관해 그물에 대한 많은 예제들이 있으며, 가장 인기있는 것이 Cagatay 's에서 나온 것 같습니다. 이런 식으로 양쪽에서 힘을 얻을 수 있습니다. 그러면 빈은 다음과 같이 보일 것입니다.
```
@Component
@Scope("view")
public class AnneeBean {
    @Autowired
    private AnneeMetier anneeMetier;
    private List<Annee> listeAnnees;

    @PostConstruct
    public void init() {
        listeAnnees = anneeMetier.getAllAnnees();
    }

    public List getListeAnnees() {
        return listeAnnees;
    }

    public void setListeAnnees(List listeAnnees) {
        this.listeAnnees = listeAnnees;
    }
}
```

Spring을 배우므로 구성 요소 검사를 사용하고 주석을 사용하여 스프링 빈을 구성하는 것이 가장 좋습니다. 다음을 수행하십시오.

프로젝트를 컴파일하고 실행하십시오.
==============================
2.당신은 초기화되지 않은 anneeMetier라는 private 객체의 메소드를 호출 할 곳인 getListeAnnees를 사용하고 있습니다. 코드에서 초기화되지 않은 setAnneeMetier 메소드를 통해 해당 객체를 초기화하므로 null입니다. 다음 중 하나를 수행하여 문제를 해결할 수 있습니다.

편집 : pL4GU33의 의견을 유용 할 수 있으므로 답변에 그의 의견을 추가 할 :

공용 목록 getListeAnnees () { if (anneeMetier == null) { return Collections.emptyList (); } listeAnnees = anneeMetier.getAllAnnees (); return listeAnnees; }

그의 해결책은 더 유형에 구속력이 없으므로 나는 그의 말을 포기한다.
