我需要使用 Hibernate、Spring 和 Lombok 制作一个空白项目。我做到了，但决定通过添加一些逻辑来进行实验。为 SessionFactory 添加 bean 后，项目停止启动并出现错误

描述：组件需要一个名为“entityManagerFactory”的 bean，但无法找到。操作：考虑在您的配置中定义一个名为“entityManagerFactory”的 bean。

请告诉我可能出了什么问题？

请告诉我可能是什么原因造成的。使用 PATCH 方法执行端点时，CrudRepository 中的 save() 方法不起作用。没有发生异常，端点执行后数据库中根本没有任何影响。端点更改用户银行卡的状态。

public boolean changeStatus(UUID cardId, String newStatus) {
    boolean result = false;
    Optional<Card> cardOpt = cardRepository.findById(cardId);
    if (cardOpt.isPresent()) {
        Card card = cardOpt.get();
        card.setStatusType(StatusType.valueOf(newStatus));
        cardRepository.save(card);
        result = true;
    }
    return result;
}

public interface CardRepository extends JpaRepository<Card, UUID> {
    List<Card> findCardsByAccountId(UUID accountId);
    List<Card> findCardsByClientId(UUID clientID);
    @Query(value = "SELECT status FROM card WHERE id = :cardId", nativeQuery = true)
    Optional<String> findStatusById(@Param("cardId") UUID cardId);
}
