<tx:advice id="txAdvice" transaction-manager="transactionManager">  
    <tx:attributes>  
        <tx:method name="*" propagation="REQUIRED" />  
     </tx:attributes>  
 </tx:advice>  

 <aop:config>  
     <aop:pointcut id="interceptorPointCuts" expression="execution(* service.*.*(..))" 

/>
 <aop:advisor advice-ref=“txAdvice” pointcut-ref=“interceptorPointCuts” />
 </aop:config>
