POJO와 XML 기반 AOP

• 기존의 어노테이션 기반으로 작성한 AOP 예제를 POJO와 XML 기반으로 전환하기 위해 변경해야할 곳은
  Aspect가 정의되어 있는 MyAspect.java와 스프링 설정 정보 XML 파일입니다.

@ 어노테이션 기반 코드

[기존] @ 어노테이션 기반 - MyAspect.java가 스프링 프레임워크에 종속

package aop001;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.JoinPoint;

@Aspect
public class MyAspect {
    @Before("execution(* runSomething())")
    public void before(JoinPoint joinPoint) {
        System.out.println("얼굴 인식 확인: 문 개방");
    }
}
