Using @Autowired Spring service in Hibernate UserType instance

Question

What I am trying to do is to use autowired Spring Service in my UserType. The problem is (as I believe) that Hibernate uses AuthorType.INSTANCE, and it's constructed with no parameters, meaning that field BookShelfService is null.

Is there any way to fix it?

PersonType (extends CommonType which implements UserType):

@Component
public class PersonType extends CommonType {
    public static final PersonType INSTANCE = new PersonType();
    private BookShelfService shelfService;

    @Autowired
    public void setShelfService(BookShelfService shelfService) {
        this.shelfService = shelfService;
        System.out.println("BSS is SET in "+ this);
    }

    public PersonType() {
        super(Person.class);
        System.out.println("PT instd: "+this);
    }

    @Override
    public int[] sqlTypes() {
        return new int[] {LongType.INSTANCE.sqlType()};
    }

    @Override
    public Object nullSafeGet(ResultSet resultSet,
                              String[] strings,
                              SharedSessionContractImplementor sharedSessionContractImplementor,
                              Object o) throws HibernateException, SQLException {
        long id = Long.parseLong(resultSet.getString(strings[0]));
        System.out.println("BSS in " + this + ": "+shelfService);
        Optional<Person> person = shelfService.findPersonById(id); ** NullPointerException HERE **

        if (person.isPresent()) {
            return person;
        } else throw new IllegalArgumentException("SEVERE: No Person found with id: "+id);
    }

    @Override
    public void nullSafeSet(PreparedStatement preparedStatement,
                            Object o, int i,
                            SharedSessionContractImplementor sharedSessionContractImplementor) throws HibernateException, SQLException {
        if (o == null) {
            preparedStatement.setNull(i, LongType.INSTANCE.sqlType());
        } else {
            preparedStatement.setLong(i, ((Person) o).getId());
        }
    }
}

BookShelfService:

@Service
public class BookShelfService {
    private BooksRepository booksRepository;
    private AuthorsRepository authorsRepository;
    private BookOwnersRepository bookOwnersRepository;
    private PeopleRepository peopleRepository;

    @Autowired
    public BookShelfService(BooksRepository booksRepository,
                            AuthorsRepository authorsRepository,
                            BookOwnersRepository bookOwnersRepository,
                            PeopleRepository peopleRepository) {
        this.booksRepository = booksRepository;
        this.authorsRepository = authorsRepository;
        this.bookOwnersRepository = bookOwnersRepository;
        this.peopleRepository = peopleRepository;
    }

    public BookShelfService() {
    }

    public List<Book> findBooksByAuthorNameAndSurname(String name, String surname) {
        Optional<Person> person = peopleRepository.findPersonByNameAndSurname(name, surname);

        if (!person.isPresent())
            throw new IllegalArgumentException("No Person found with name: " + name + ", surname: " + surname);

        Optional<Author> author = authorsRepository.findAuthorByPerson(person.get());

        if (!author.isPresent())
            throw new IllegalArgumentException("No Author found with name: " + name + ", surname: " + surname);

        return booksRepository.findBooksByAuthor(author.get());
    }
        // *** etc.
}

By the way, I noticed that AuthorType gets instantiated in my case 18 times and the 6th in the output list is always the one that is used and produces NullPointerException.
