Das Beibehalten einer JMolecules Aggregate Association funktioniert nicht, wenn EntityManager verwendet wird ⇐ Java

[Anonymous]

Ich habe mehrere von JMolecules verwaltete Aggregatstämme, die Assoziationen verwenden. Bei der Beibehaltung mit einem Spring Data JPA-Repository werden die Zuordnungen ordnungsgemäß konvertiert.
Bei der Beibehaltung desselben Objekts und seiner Zuordnungen mithilfe einer Entity-Manager-Instanz schlägt dies jedoch fehl.
Ein Test, der beide Szenarien zeigt, ist:

Code: Select all

@DataJpaTest()
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@TestPropertySource(properties = """
spring.jpa.show-sql=true
""")
@Import([IntegrationTestConfiguration, CatalogIntegrationTestConfiguration])
class AssociationWithEntityManagerSpec extends AbstractRepositorySpecification {

@Autowired
ArticleRepository repository

@Autowired
MarketDataRepository marketDataRepository

@Autowired
RicRateRepository ricRateRepository

ArticleFactory entityFactory = new ArticleFactory()
RicRateFactory ricRateFactory = new RicRateFactory()
MarketDataFactory marketDataFactory = new MarketDataFactory()

def "find by id with repository"() {
given:
RicRate rate = ricRateFactory.newObject(id: new RicRateIdentifier('HKD'))
rate = ricRateRepository.save(rate)

MarketData marketData = marketDataFactory.newObject(rate: Association.forAggregate(rate))
marketData = marketDataRepository.save(marketData)

Article article = repository.save(entityFactory.newObject(marketData: Association.forAggregate(marketData)))

when:
Optional result = repository.findById(article.id)

then:
result.isPresent()
}

def "find by id with entity manager"() {
given:
RicRate rate = ricRateFactory.newObject(id: new RicRateIdentifier('HKD'))
rate = entityManager.merge(rate)

MarketData marketData = marketDataFactory.newObject(rate: Association.forAggregate(rate))
marketData = entityManager.merge(marketData)

Article article = repository.save(entityFactory.newObject(marketData: Association.forAggregate(marketData)))

when:
Optional result = repository.findById(article.id)

then:
result.isPresent()
}

}

Der Test mit dem Entity Manager zeigt die folgende Ausnahme, die aussieht, als würde der Datenbankschlüsselwert HKD für die Tarifzuordnung verwendet, um einen MarketDataIdentifer zu erstellen, der eine UUID ist. Es sollte wirklich einen RicRateIdentifier erstellen
Also gehe ich davon aus, dass ohne das Repository einige Metadaten fehlen, um die Zuordnung richtig zu lesen?
Da das Byte-Buddy-Plugin die Entität mit Attributkonvertern erweitert, gehe ich davon aus, dass es keine Rolle spielt, ob das Repository oder der Entitätsmanager verwendet wird.
