axon - Axonframework が jpa でイベント データを挿入しない

Question

入門ガイド ( http://www.axonframework.org/axon-2-quickstart-guide/ ) を実行しましたが、問題なく動作します。

FileSystemEventStore を JpaEventStore に置き換えようとしましたが、イベントが保存されません。

これが私の構成です：

public static void main(String[] args) {
    CommandBus commandBus = new SimpleCommandBus();
    CommandGateway commandGateway = new DefaultCommandGateway(commandBus);
    //EventStore eventStore = new FileSystemEventStore(new SimpleEventFileResolver(new File("./events")));

    EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory( "cqrsworkshop" );
    EntityManager entityManager = entityManagerFactory.createEntityManager();
    SimpleEntityManagerProvider entityManagerProvider = new SimpleEntityManagerProvider(entityManager);
    EventStore eventStore = new JpaEventStore(entityManagerProvider);

    EventBus eventBus = new SimpleEventBus();
    EventSourcingRepository<ToDoItem> repository = new EventSourcingRepository<ToDoItem>(ToDoItem.class, eventStore);

    repository.setEventBus(eventBus);

    AggregateAnnotationCommandHandler.subscribe(ToDoItem.class, repository, commandBus);
    AnnotationEventListenerAdapter.subscribe(new ToDoEventHandler(), eventBus);

    final String itemId = UUID.randomUUID().toString();
    commandGateway.send(new CreateToDoItemCommand(itemId, "Need to do this"));
    commandGateway.send(new MarkCompletedCommand(itemId));

    entityManagerFactory.close();
}
