AOP Declarative Transaction Management

[Helena]

I don't think you need to declare that, just set the transactional advice

<aop:config>
        <aop:pointcut id="dataAccessOperation"
                      expression="execution(* com.foo.infrastructure.SystemArchitecture.dataAccessOperation())"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="dataAccessOperation"/>
    </aop:config>

or an interface implemented by all dao's which is proxied:

<aop:config>
        <aop:pointcut id="dataAccessOperation"
                      expression="this(com.foo.service.MyServiceInterface))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="dataAccessOperation"/>
    </aop:config>
