@Transactional配置事务未提交到数据库

小弟在研究事务，目前在学习@Transactional来配置全局事务，但无法更新数据库，请大哥们指点一下

appliactioncontext.xml

	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

		<property name="username" value="scott"></property>

		<property name="password" value="tiger"></property>

		<property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"></property>

		<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>

	</bean>

	<bean id="sessionFactory"

		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

		<property name="dataSource" ref="dataSource"></property>

		<property name="mappingResources">

			<list>

				<value>com/data/UserInfo.hbm.xml</value>

			</list>

		</property>

		<!-- 方言 -->

		<property name="hibernateProperties">

			<value>

				hibernate.dialect=org.hibernate.dialect.Oracle10gDialect

			</value>

		</property>

	</bean>

	<!-- 事务管理器 -->

	 <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

		<property name="sessionFactory" ref="sessionFactory"></property>

	</bean>

 	<tx:annotation-driven transaction-manager="transactionManager"/> 

DAO层

@Repository("workoutBusiness")

@Transactional

public class WorkoutBusiness implements IWorkoutBusiness {

	@Resource(name="sessionFactory")

	SessionFactory sessionFactory;

	@Transactional(propagation=Propagation.REQUIRED)

	public void saveNewUser(UserInfo user)  {

	//	Session session = sessionFactory.openSession();

		Session session =	sessionFactory.getCurrentSession();

	//	Transaction tran = session.beginTransaction();

	//	tran.begin();

			session.save(user);

		//tran.commit();

		//session.close();

	}



}

使用HIBERNATE的事务提交后能插进数据，但用spring @Transactionnal就没反映，也没报错。。。。
