SPI fragment can not be introduced by `@NoRepositoryBean`

[quaff]

Thanks to 4df7a16, Spring Data can introduce SPI fragments by specifying them in spring.factories, it works fine if repository extends the SPI interface, but it will fails if repository extends an @NoRepositoryBean base repository which extends the SPI interface.

Given:

public interface Fragment {
	String getName();
}

public class FragmentImpl implements Fragment {
	public String getName() {
		return "fragment";
	}
}

---

Following interface hierarchies works:

@NoRepositoryBean
interface ExcludedRepository extends JpaRepository<TestEntity, Long> {
}

interface TestEntityRepository extends ExcludedRepository, Fragment {
}

---

Following interface hierarchies fails:

@NoRepositoryBean
interface ExcludedRepository extends JpaRepository<TestEntity, Long>, Fragment {
}

interface TestEntityRepository extends ExcludedRepository {
}

It caused by FragmentMetadata::getFragmentInterfaces doesn't consider indirect super interfaces.

spring-data-commons/src/main/java/org/springframework/data/repository/config/FragmentMetadata.java

Lines 51 to 57 in 4718c45

	public Stream<String> getFragmentInterfaces(String interfaceName) {
	Assert.hasText(interfaceName, "Interface name must not be null or empty");
	return Arrays.stream(getClassMetadata(interfaceName).getInterfaceNames()) //
	.filter(this::isCandidate);
	}

I'll try to fix it later.

We intentionally do not consider super-interfaces for repository fragment detection so in that sense the code works as designed and is not broken. Super-interfaces can reside in other packages and then we open a can of worms asking for consideration of fragment implementations that can reside in other packages, regardless of the SPI feature we recently shipped.
