Spring websocket OpenSessionInviewWinterCeptor Spring WebSocket

有人在SpringWebSocket消息上实现了OpenSessionInView吗？我需要实现这一点，并希望一些现有的材料

我创建了一些测试内容，如下面所示，但我遇到了TransactionException，可能是因为当您发回回复时，您的会话需要同时处理发送和接收消息

public class OpenSessionInViewChannelInterceptor extends ChannelInterceptorAdapter{

    @Inject
    private SessionFactory sessionFactory;

    @Override
    public Message<?> preSend(Message<?> message, MessageChannel channel) {
        SessionFactory sf = sessionFactory;
        if (!TransactionSynchronizationManager.hasResource(sf)) {
            // New Session to be bound for the current method's scope...
            Session session = openSession();
            try {
                TransactionSynchronizationManager.bindResource(sf, new SessionHolder(session));
                return super.preSend(message, channel);
            }
            finally {
                SessionFactoryUtils.closeSession(session);
                TransactionSynchronizationManager.unbindResource(sf);
            }
        }
        else {
            // Pre-bound Session found -> simply proceed.
            return super.preSend(message, channel);
        }       

    }

    protected Session openSession() throws DataAccessResourceFailureException {
        try {
            Session session = sessionFactory.openSession();
            session.setFlushMode(FlushMode.MANUAL);
            return session;
        }
        catch (HibernateException ex) {
            throw new DataAccessResourceFailureException("Could not open Hibernate Session", ex);
        }
    }

}

是的，我创造了这个。我现在的解决方法是在控制器上使用“@Transactional”，这很难看，在ListenableFuture场景中不起作用（还没有测试），这是您想要的“@MessageMapping，也是Spring使用反应式方法的方向
