<aop:config>

<!-- <aop:pointcut expression="execution(* say*(..))" id="sayPointcut"/> -->

<aop:pointcut expression="execution(* say*(java.lang.String))" id="sayPointcut"/>

                  <aop:aspect ref="logAspect">

                  <aop:before method="beforeLogging" pointcut-ref="sayPointcut"/>

                  </aop:aspect>

</aop:config>

 

 

</beans>

 

                  public void beforeLogging(JoinPoint joinPoint){

                                   System.out.println(joinPoint.getSignature().getName() + "메소드 호출 전 :" +

                                                                       joinPoint.getArgs()[0]);

                  }

 

결과
