■ XML 스키마를 이용하여 Aspect를 설정하는 경우에도 '&&'(and)나 '||'(or) 연산자를 사용

<aop:config>   <aop:aspect id="test" ref="testAspect">    <aop:pointcut expression="execution(* sp.aop.service.*.get*()) and execution(* sp.aop.service.*.check*(..))" id="publicPointcut"/>    <aop:before method=""/>   </aop:aspect>  </aop:config>
