org.springframework.data.mapping.model.MappingException: Kann ein komplexes Objekt nicht als Schlüsselwert verwenden

Question

arbeite mit Spring Boot und MongoDB. habe das Repository für mein Modell geschrieben und meine eigene Logik geschrieben, um die ID mit mongo inc zu erhöhen.

gradle Test

die Tests mit der folgenden Ausnahme fehlschlagen, während tun.

kann mir empfehlen, was falsch mache

EDIT: Zum Beispiel: Anwendungsklasse ist die Domäne

class Application implements Serializable { 

String id 
APIKey apiKey 
Map actions = [:] 

Application() { 
} 

Application(APIKey apiKey) { 
    this.apiKey = apiKey 
    List customerActionsList = [] // added some actions 
    actions.put(Role.User, customerActionsList) 
} 

apikey:

String apiKey 
String application 
DateTime whenCreated 
boolean active 

APIKey() { 
} 

APIKey(String application, DateTime whenCreated, boolean active) { 
    this.apiKey = generateAPIKey(application) 
    this.application = application 
    this.whenCreated = whenCreated 
    this.active = active 
} 

Repository Klasse ist wie folgt:

@Component 
class ApplicationRepositoryImpl implements ApplicationRepository { 

private final Logger logger = LoggerFactory.getLogger(ApplicationRepositoryImpl.class) 

@Autowired 
ApplicationRepositoryMongo applicationRepositoryMongo 

@Autowired 
SequenceRepository sequenceRepository 

@Override 
Serializable save(Application application) { 
    application.id = application.id?:sequenceRepository.getNextSequenceId(Application.simpleName).sequence 
    return applicationRepositoryMongo.save(application).id 
} 

@Override 
Application find(String id) { 
    return applicationRepositoryMongo.findOne(id) 
} 

ich die ID der Anwendungsklasse am Inkrementieren als

public SequenceId getNextSequenceId(String type) { 
    //get sequence type 
    Query query = new Query(Criteria.where("id").is(type)) 
    //increase sequence id by 
    Update update = new Update() 
    update.inc('sequence', 1) 
    //return new increased i 
    FindAndModifyOptions options = new FindAndModifyOptions() 
    options.returnNew(true) 
    //this is the magic happened 
    SequenceId seqId = mongoOperation.findAndModify(query, update, options, SequenceId.class) 
    return seqId 
} 

folgt Während das Domänenobjekt Speichern der oben Ausnahme bekommen. Ich habe alle Mongo-Konfiguration gemacht. Die Konfiguration funktioniert für andere Domänen.

Answer 1

Es gibt eine offene Verbesserung im Frühjahr Don't require Converters for Complex classes that are used as Ids. Momentan hat Spring entschieden, es nicht zu unterstützen.

beschlossen, es nicht überhaupt scheint ganz klar
