为什么我的Spring Boot存储库没有被识别为bean

我的小应用程序应该是电影界的潮流先锋。 我想使用一个In-Memory H2数据库来进行票务预订和其他操作。

预订实体

package fr.univlyon1.m2tiw.tiw1.metier;
...

@Entity
public class Reservation {
  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column
  private Long id;

  @Column
  private String prenom;

  @Column
  private String nom;

  @Column
  private String email;

  @Column
  private boolean paye;

  @Column(nullable = false)
  private String seanceId;

  public Reservation() {
  }
  ...

存储库 

@Repository
public interface SpringJPAReservationDAO extends CrudRepository<Reservation, Long> {
  List<Reservation> getBySeanceId(String seanceId);

  Reservation getByEmail(String email);

  Reservation getByEmailAndSeanceId(String email, String seanceId);
}

SpringBoot运行 

@SpringBootApplication
@EnableTransactionManagement
@EnableAspectJAutoProxy(proxyTargetClass = true)
@EnableJpaRepositories("fr.univlyon1.m2tiw.tiw1.dao")
@EntityScan("fr.univlyon1.m2tiw.tiw1.metier")
public class Application {

  public static void main(String[] args) throws IOException, URISyntaxException, BeansException, ClassNotFoundException {
     SpringApplication.run(Application.class, args);
  }
}

应用程序属性

至少在intelij中，似乎该存储库被识别为bean。 我找不到问题所在。

pom.xml 应用程序中的其他类使用了某些依赖项。我认为他们没有任何问题，但谁知道

我解决了。

我实际上有一个带有声明的bean的SpringConfig文件。

SpringConfig.java 

@Configuration
public class SpringConfig 
{
    @Bean
    public JSONCinemaDAO jsonCinemaDAO() throws IOException{
        return new JSONCinemaDAO();
    }

    @Bean
    public SalleDAOImpl  salleDAOImpl(JSONCinemaDAO cinemaDAO) throws IOException{
        return new SalleDAOImpl(cinemaDAO);
    }

    @Bean
    public ProgrammationDAOImpl programmationDAOImpl(SalleDAOImpl salleDAO,JSONCinemaDAO cinemaDAO)
            throws IOException, ParseException{
        return new ProgrammationDAOImpl(salleDAO,cinemaDAO);
    }

    @Bean
    public SeanceManager seanceManager(ProgrammationDAOImpl p_DAO, SpringJPAReservationDAO r_DAO) throws IOException, ParseException{
        return new SeanceManager(p_DAO,r_DAO);
    }

    @Bean
    public CinemaRessourceFilms cinemaRessourceFilms(ProgrammationDAOImpl p_DAO,SpringJPAReservationDAO r_DAO,
                                                     SeanceManager child) throws IOException, ParseException{
        return new CinemaRessourceFilms(p_DAO,r_DAO,child);
    }

    @Bean
    public CinemaRessourceReservations cinemaRessourceReservations(ProgrammationDAOImpl p_DAO,SpringJPAReservationDAO r_DAO,
                                                                   SeanceManager child) throws IOException, ParseException{
        return new CinemaRessourceReservations(p_DAO, r_DAO, child);
    }

    @Bean
    public CinemaRessourceSalles cinemaRessourceSalles(ProgrammationDAOImpl p_DAO, SpringJPAReservationDAO r_DAO, SeanceManager child,
                                                       SalleDAOImpl salleDAO) throws IOException, ParseException{
        return new CinemaRessourceSalles(p_DAO,r_DAO,child, salleDAO);
    }

    @Bean
    public CinemaRessourceSeances cinemaRessourceSeances(ProgrammationDAOImpl p_DAO,SpringJPAReservationDAO r_DAO,
                                                         SeanceManager child) throws IOException, ParseException{
        return new CinemaRessourceSeances(p_DAO,r_DAO,child);
    }
}

我刚刚删除了它，并根据其角色在类中添加了 @Component 或 @Service 批注
