SSH事务的管理配置异常

    <!-- 定义事务管理器（声明式的事务） -->    
    <bean id="transactionManager"  
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">  
        <property name="sessionFactory" ref="sessionFactory" />  
    </bean>   

<bean id="txManager" abstract="true" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
   <property name="transactionManager" ref="transactionManager" />
   <property name="transactionAttributes">
    <props>  
     <prop key="add*">PROPAGATION_REQUIRED</prop>
     <prop key="update*">PROPAGATION_REQUIRED</prop>
     <prop key="handle*">PROPAGATION_REQUIRED</prop>
     <prop key="save*">PROPAGATION_REQUIRED</prop>
     <prop key="create*">PROPAGATION_REQUIRED</prop>
     <prop key="*">PROPAGATION_REQUIRED</prop>
    </props>
    </property>
</bean>

配置完之后还是报只读权限的异常
