Я пытаюсь предоставить общий репозиторий Parrent для всех моих репозиториев «для каждого агрегированного корня», который я могу позже использовать полиморфно.

Я создал родительский «составленный репозиторий». Который должен быть реализован другими конкретными репозиториями.

 @Repository
public interface ZoneNameJpaRepository extends GenericJpaRepository<ZoneDTO, GenericPJM_Id> {
}
  

 public interface GenericJpaRepository<T extends GenericPJM, ID extends GenericPJM_Id>
    extends JpaRepository<T, ID>, GenericFindRepository<T, ID> {}
  

 @Repository
public interface GenericFindRepository<T extends GenericPJM, ID extends GenericPJM_Id> {
    List<T> findAll(boolean isLazySufficient) throws ClassNotFoundException;
    T find(ID id,boolean isLazySufficient) throws ClassNotFoundException;
}
  

 public class GenericFindRepositoryImpl<T extends GenericPJM, ID extends GenericPJM_Id> implements GenericFindRepository<T, ID> {

  @Autowired EntityManager entityManager;
  @Autowired DTO_NameAndClassMap dto_nameAndClassMap;

  private Class<T> genericType;

  public GenericFindRepositoryImpl() {
    genericType =
            (Class<T>) GenericTypeResolver.resolveTypeArgument(getClass(), GenericFindRepository.class);
    System.out.println("GenericFindRepositoryImpl Constructor: "   genericType.getSimpleName());
  }

  @Override
  public List<T> findAll(boolean isLazySufficient) throws ClassNotFoundException {
    if (isLazySufficient) {
      return lazyFindAll();
    } else {
      return findAll();
    }
  }

  @Override
  public T find(ID id, boolean isLazySufficient) throws ClassNotFoundException {
    if (isLazySufficient) {
      return lazyFind(id);
    } else {
      return find(id);
    }
  }

  private T find(ID id) {
    System.out.println("_________________GenericFIndRepository find_____________________");
    return entityManager.find(genericType, id);
  }

  private T lazyFind(ID id) throws ClassNotFoundException {
    EntityGraph entityGraph = entityManager.getEntityGraph("Generic_lazy_loading");
    Map hints = new HashMap();
    hints.put("javax.persistence.fetchgraph", entityGraph);
    System.out.println("_________________GenericFIndRepository find_____________________");
    return (T) entityManager.find(genericType, id, hints);
  }

  private List<T> lazyFindAll() throws ClassNotFoundException {
    EntityGraph entityGraph = entityManager.getEntityGraph("Generic_lazy_loading");
    List<T> results =
        entityManager
            .createQuery(getQueryStringToFindAll(), genericType)
            .setHint("javax.persistence.fetchgraph", entityGraph)
            .getResultList();
    System.out.println("_________________GenericFIndRepository lazyFindAll()_____________________");
    return results;
  }

  private List<T> findAll() throws ClassNotFoundException {
    EntityGraph entityGraph = entityManager.getEntityGraph("Generic_lazy_loading");
    List<T> results =
        entityManager.createQuery(getQueryStringToFindAll(), genericType).getResultList();
    System.out.println("_________________GenericFIndRepository lazyFindAll()_____________________");
    return results;
  }

  private String getEntityNameBasedOnClass(Class desiredClass) {
    // Class<?> aClass = T;
    Table table = genericType.getAnnotation(Table.class);
    String tableName = table.name();
    System.out.println("GENERIC_FIND_REPOSITORY findAllByClass() table name found: "   tableName);
    return desiredClass.getSimpleName();
  }

  private String getQueryStringToFindAll() {
    StringBuilder query = new StringBuilder();

    query.append("from "   getEntityNameBasedOnClass(genericType));
    return query.toString();
  }
}
  

Я получаю следующую ошибку:
