我想实现这里提到的jpa存储库。我想我的问题是我想使用jpa存储库本身的一些函数 @Autorwired 是的，但我不能完全肯定
错误消息：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'addBothStudentsHandler': Unsatisfied dependency expressed through method 'setMajorRepository' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'majorRepository' defined in io.asiam.tansiq.repositories.MajorRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot create inner bean '(inner bean)#78f146b5' of type [org.springframework.data.repository.core.support.RepositoryFragmentsFactoryBean] while setting bean property 'repositoryFragments'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#78f146b5': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customMajorRepositoryImplFragment': Cannot resolve reference to bean 'customMajorRepositoryImpl' while setting constructor argument; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customMajorRepositoryImpl': Unsatisfied dependency expressed through field 'majorRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'majorRepository': FactoryBean threw exception on object creation; nested exception is java.lang.NullPointerException

到目前为止，我所尝试的：
1-尝试使用基于setter的 @Autowired 而不是基于字段（但无更改）
2-尝试使用 @Lazy 也没有什么变化

代码：

custommajorrepository.java

public interface CustomMajorRepository {
    void addStudentToMajor(Student student, Major major);
    void increaseMajorLimit(UUID majorId, int amount);
}

custommajorrepositoryimpl.java

private MajorRepository majorRepository;
    public MajorRepository getMajorRepository() {
        return majorRepository;
    }
    @Autowired
    public void setMajorRepository(MajorRepository majorRepository) {
        this.majorRepository = majorRepository;
    }
// rest of implementation details

majorrepository.java

@Lazy
public interface MajorRepository extends JpaRepository<Major, UUID>, CustomMajorRepository {
}
