Spring Data Jpa 应用程序正在尝试刷新，导致@MappedSuperClass存储库错误-无法为方法公共抽象创建查询，不是实体

我有一个应用程序，计算Roto值从给定的统计。我重构了它，使用@MapperSuperclass，而不是只保存1个实体（额外的字段设置为0），现在我得到了一个错误。奇怪的是，我的应用程序仍然运行并完成其工作，只有在应该关闭时才会抛出错误。
这是我的结束语。除了遇到Exception的语句之外，这部分与重构之前完全相同。我不明白的是为什么它试图刷新。

所以很明显，这与添加@MappedSuperclass有关，但我不知道是什么。
这是我的repo-

public interface StatsRepository<T extends Stats> extends CrudRepository<T, StatsId> {
    List<T> findAllByWeek(int week);
    List<T> findAllByName(String name);
}

这两个子节点都只是用它们的Pojo扩展这个接口

public interface ChampRepository extends StatsRepository<ChampStats> { }

我的配置文件提供了我的服务的Repo bean-

@Configuration
public class RepositoryConfiguration {
    @Autowired private StatsRepository<ChampStats> champRepository;
    @Autowired private StatsRepository<PsdStats> psdRepository;

    @Bean
    public StatsRepository repository(League league) {
        if (league.equals(League.CHAMPIONS)) {
            return champRepository;
        } else if (league.equals(League.PSD)) {
            return psdRepository;
        }
        throw new BadInput("The given league is not valid");
    }
}
spring-data-jpa

我仍然不明白为什么这个错误只发生在应用运行完成之后，但错误的原因是Sping Boot 试图将StatsRepository接口初始化为Spring bean，因为它扩展了CrudRepository。
修复方法只是将@NoRepositoryBean注解添加到StatsRepository
