entitymanager.persist不会插入到数据库中

Question

我使用实体管理器来持久存入数据库。当我调用这个方法时：createCraResponse调用entitymanager。坚持（）。我在日志中看不到“插入Sql语句”。但是在我为select添加一个调用之后，它会插入到Database中但在日志中无异常地停止运行。

protected override void OnWindowCreated(WindowCreatedEventArgs args){
    base.OnWindowCreated(args);

    var window = args.Window;
    window.CoreWindow.CharacterReceived += CoreWindow_CharacterReceived;
}

private void CoreWindow_CharacterReceived(CoreWindow sender, CharacterReceivedEventArgs args)
{
    System.Diagnostics.Debug.WriteLine("Received Event KeyCode: {0}, KeyStatus: {1}", args.KeyCode, args.KeyStatus.ToString());
}

我扩展了这个类： AbstractBaseDao：

@Repository
@Transactional(propagation=Propagation.REQUIRED)
public class respDaoImp extends AbstractBaseDao implements resDao {

@Override

    public void createCraResponse(Response Response) {
        entityManager.persist(Response);
    }
