spring - 同じインターフェースを実装する複数の Bean

Question

正確な使用法は次のとおりです。

    @Slf4j
public class Client<E, Key> {
    @Getter @NonNull private final UpdateListener<E, Key> updateListener;
    @NonNull private final SubscriptionFactory subscriptionFactory;
    @NonNull private final Map<Key, Instant> updatedRegistry = new ConcurrentHashMap<>();

    public Client(UpdateListener<E, Key> updateListener,
                  SubscriptionFactory subscriptionFactory) {
        this.updateListener = updateListener;
        this.subscriptionFactory = subscriptionFactory;
        this.subscriptionFactory.registerSnapshotClient(updateListener);
        log.info("Created new snapshot client for entity key [{}], update type [{}] and component qualifier [{}]",
            updateListener.getEntityKey(),
            updateListener.getOptionalChangeType(),
            updateListener.getComponentQualifier());
    }

    @RabbitListener(queues = {"#{@queueNameCreator.createUpdateQueueName(snapshotClient.getUpdateListener())}",
                                "#{@queueNameCreator.createSnapshotQueueName(snapshotClient.getUpdateListener())}"})
    public void handleMessage(Message<E> rawUpdate, @Header("last_updated") Instant newUpdatedTime) {
        ...//more code
    }
}

各「クライアント」インスタンスには、互いに衝突しないように独自の Bean ID があります。

SpEl を使用して、このオブジェクトの正確な updateListener を取得するにはどうすればよいですか?

プログラムによるアプローチと登録方法を使用した後、次の例外が発生します。

完了したら、目的の動作を実現するために次のことを行う必要があります。

@Configuration
@EnableRabbit
public static class OmbeRabbitListenerConfigurer implements RabbitListenerConfigurer {
    @Autowired ApplicationContext applicationContext;
    @Autowired SnapshotClientQueueNamesCreator snapshotClientQueueNamesCreator;
    @Autowired RabbitListenerContainerFactory rabbitListenerContainerFactory;
    @Autowired MessageConverter messageConverter;

    @Override
    public void configureRabbitListeners(RabbitListenerEndpointRegistrar registrar) {
        final Collection<SnapshotClient> snapshotClients = applicationContext.getBeansOfType(SnapshotClient.class).values();
        System.out.println(snapshotClients);

        snapshotClients.stream().forEach(bean -> {
            final String snapshotQueueName = snapshotClientQueueNamesCreator.createSnapshotQueueName(bean.getUpdateListener());
            final String updateQueueName = snapshotClientQueueNamesCreator.createUpdateQueueName(bean.getUpdateListener());

            Method method = Stream.of(bean.getClass().getMethods()).filter(x -> x.getName().equals("handleMessage")).findAny().get();

            MethodRabbitListenerEndpoint endpoint = new MethodRabbitListenerEndpoint();

            final DefaultMessageHandlerMethodFactory messageHandlerMethodFactory = new DefaultMessageHandlerMethodFactory();
            messageHandlerMethodFactory.afterPropertiesSet();

            endpoint.setMessageHandlerMethodFactory(messageHandlerMethodFactory);

            endpoint.setBean(bean);
            endpoint.setMethod(method);

            endpoint.setId(snapshotQueueName + ":" + updateQueueName + UUID.randomUUID());
            endpoint.setQueueNames(snapshotQueueName, updateQueueName);
            endpoint.setExclusive(false);

            registrar.registerEndpoint(endpoint, rabbitListenerContainerFactory);
        });
    }
}
