Компонент не может быть автоматически подключен и возвращать исключение NullPointerException

#java #spring #hibernate #jpa

#java #весна #спящий режим #jpa

Вопрос:

Я разрабатываю ERP с использованием фреймворков Spring MVC и JPA / Hibernate. Моя проблема в том, что компонент construireBilanImpl на уровне сервиса не может быть создан, потому opmanimpl что поле не может быть автоматически подключено и возвращено NullPointerException

com.ensi.erp.metier.CreerBilanImpl:

 @Transactional
@Component

public class ConstruireBilanImpl implements ConstruireBilan {

    @Autowired(required=true)
    private  OperationManager opmanimpl ;

    private float immobilisations_corporelles=sommeComptes(1266,1322);
public ConstruireBilanImpl(){};
    public void setOpmanimpl(OperationManagerImpl x){opmanimpl=x;}

    public float sommeComptes(int... doubles){
        if (this.opmanimpl==null){System.out.println("BAAAAAAAAAAAAAADDDDDDDDDD");}
        return opmanimpl.sommeComptes(doubles);


    }

com.ensi.dao.OperationMnagerImpl:

 @Component
public class OperationManagerImpl implements OperationManager {

    @PersistenceContext(unitName="ERP")
        private EntityManager em;

        public OperationManagerImpl(){};

        public void setEm(EntityManager emm){em=emm;}


        public void creerOperation(opération op) {
            if (em!=null){System.out.print(" manager de bean initialisé");}

              em.persist(op);



            System.out.println("dou5oul---------2");}

        public opération rechercherOperation(int clé){

Комментарии:

1. просто любопытно: это «компонент» в названии?

2. @AdrianShum Это было до тех пор, пока оно не подверглось вандализму.

Ответ №1:

Интерфейс OperationManager может иметь и другие классы реализации. Следовательно, Spring не сможет определить, какая реализация должна быть создана. Если это так, то приведенное ниже должно помочь. Также интерфейс не обязательно должен быть помечен как Component .

@Autowired(required=true)
@Qualifier("operationManagerImpl")
private OperationManager opmanimpl ;

Ответ №2:

Это связано с тем, что Spring не находит компонент opmanimpl , используя 

 @Autowired(required=true)
@Qualifier("operationManagerImpl")
private  OperationManager opmanimpl ;

ДОКУМЕНТ

Ответ №3:

Трассировка стека четко указывает, что у вас есть несколько компонентов, подходящих для автоматического подключения. Вы не показали свою конфигурацию, но я подозреваю, что вы используете сканирование компонентов, а затем также явно определяете компонент. Выберите один.
