求大神帮助,spring + hibernate4事务配置不起作用
spring_XXX.xml

	<bean id="txManager"

		class="org.springframework.orm.hibernate4.HibernateTransactionManager">

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

	</bean>



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



	<tx:advice id="txAdvice" transaction-manager="txManager">

		<tx:attributes>

			<tx:method name="get*" read-only="true" propagation="REQUIRED" /><!--之前是NOT_SUPPORT -->

			<tx:method name="query*" propagation="REQUIRED" read-only="true"/>   

			<tx:method name="count*" propagation="REQUIRED" read-only="true" />

			<tx:method name="find*" propagation="REQUIRED" read-only="true" />

			<tx:method name="list*" propagation="REQUIRED" read-only="true" />

			<tx:method name="save*" propagation="REQUIRED" />

			<tx:method name="update*" propagation="REQUIRED" />

			<tx:method name="remove*" propagation="REQUIRED" />

			<tx:method name="add*" propagation="REQUIRED" />

			<tx:method name="*" read-only="true" />

		</tx:attributes>

	</tx:advice>

	

	<aop:config proxy-target-class="true"> 

		<aop:pointcut id="allManagerMethod" expression="execution(* com.core.mvc.*.*(..))" />

		<aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod" />

	</aop:config>



	<context:component-scan base-package="com.core.mvc" />

java类

	

public List<Teacher> getTeacher() {

		// TODO Auto-generated method stub

		sessionFactory.getCurrentSession().getTransaction().begin();

		System.out.println("???:" + sessionFactory.getCurrentSession().getTransaction().isActive());

		String sql = "select new Teacher(t.id,t.name) from Teacher t";

		Query query= sessionFactory.getCurrentSession().createQuery(sql);

		query.setFirstResult(0);

		query.setMaxResults(10);

		List<Teacher> list = query.list();

		for(Teacher j:list){

			System.out.println(j.getName() + "," + j.getId());

		}

		sessionFactory.getCurrentSession().getTransaction().commit();

		System.out.println("????????:" + sessionFactory.getCurrentSession().getTransaction().isActive());

		return list;

	}

原本hibernate3是没问题的,现在换了hibernate4,发现session相关方法createQuery,get等,都必须在开启事物才能工作,否则弹出XXX is not valid without active transaction(具体在hibernate源码代理类有些),但是现在hibernate4的事务配置不生效,导致要人手sessionFactory.getCurrentSession().getTransaction().begin()才能生效.

请各位大神看看,AOP事务在hibernate4上面的配置为什么不生效?
------解决方案--------------------
spring已经不给hibernate4提供getHibernateTemplate()方法做事务处理了
