春のデータリポジトリを扱うときに奇妙な振る舞いを見つけました。春のデータリポジトリStackOverflow
私は、これらのクラスとインタフェースを書いた：私はUserRepositoryImplをテストしようとすると
@Transactional(readOnly = true)
public interface UserRepository extends Repository<User, Integer> {
@Transactional
@Modifying
@Query("DELETE FROM User u WHERE u.id=:id")
int delete(@Param("id") int id);
@Transactional
User save(User user);
User findOne(Integer id);
List<User> findAll();
}
public interface AbstractRepository<T> {
T save(T user);
// false if not found
boolean delete(int id);
// null if not found
T get(int id);
List<T> getAll();
}
@Repository
public class UserRepositoryImpl implements AbstractRepository<User> {
@Autowired
private JpaUserRepository repository;
@Override
public User save(User user) {
return repository.save(user);
}
@Override
public boolean delete(int id) {
return repository.delete(id) != 0;
}
@Override
public User get(int id) {
return repository.findOne(id);
}
@Override
public List<User> getAll() {
return repository.findAll();
}
}

を投げている私は、保存（といくつかの問題があることを確認）方法。また、delete（）メソッドでstackoverflowがスローされます。
私はすでに解決策を見つけました。私の問題は、リポジトリインタフェースを拡張するインタフェースの名前を（例えば）JpaUserRepositoryに変更すると消えます。
質問は「何が起こっているのですか」です。スプリングデータリポジトリを実装するインターフェイス名がパターンと一致すると、stackoverflowがスローされる理由Classnameリポジトリ？
