spring - 尝试在我的 WAR 中运行 Spring @Transactional 服务方法时出现 "transaction is not active"

Question

我正在使用 Spring 3.1.1.RELEASE、Hibernate 4.1.0.Final 和 JBoss 7.1.1.Final。当我尝试运行已将方法注释为 @Transactional 的服务方法时，事务完成后出现以下错误:

19:25:43,968 WARN  [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (http--127.0.0.1-8080-1) SQL Error: 0, SQLState: null

这是我在 Spring 应用程序上下文中设置数据源/实体管理器的方式:

有什么想法可以解决这个问题吗？

编辑:添加我标记为@Transactional的方法...

@Service("trainingSessionService")
@Transactional
public class TrainingSessionServiceImpl implements TrainingSessionService
{
    …
    public TrainingSession createOrUpdateTrainingSessionFromOrder(final Order order)
    {
        TrainingSession trSession = m_trainingSessionDao.findByOrderNumber(order.getId());

        LOG.info("Creating/updating training session associated with order #" + order.getId() + " associated with account " + (order.getAccount() != null ? order.getAccount().getAccountName() : "unknown"));;
        if (trSession == null)
        {
            trSession = new TrainingSession();
        } // if
