as i studied i feel like master of AOP but as time gone by i forget how to use
and re searching online guide of AOP
so I want summarize about use of AOP
Hope that it would be helpful me and you guys


The first wild card means method type : public, private, protected, *(all)

If AopTest.class exist in different package


execution(* com.sang.hwa.AopTest.*(..))

if AopTest.class exist in same package 

all method mapping in AopTest.class


execution(* AopTest.*(..))

//If class name has xxxxController.class it will be mapped
execution(public * com.sns.controller..*Controller.*(..))



package com.sns.common.aspect;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * {@link SnsPointDay} 의 point-cut 지정 및 결과 코드 처리를 위한 어노테이션
 * 
 */
@Target({ ElementType.METHOD, ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SnsPointDay {

	public String div() default "00";

	public String category();

	public String item();

	public int point() default 1;

	public String status() default "";

}

@Before(@annotation(com.sns.common.aspect.SnsPointDay))

@AfterReturning("@annotation(point)")
	public void afterControllerWithPoint(JoinPoint jp, SnsPoint point) throws Throwable {

        }

//Annotation Expression 

//$$(And), ||(or), !(not)

@Pointcut("operation() || execution() || @annotation(pointDay)")


@Before("execution(* *.*(..)) && target(target) && args(a,b)")
public void logParameter(Object target, dobule a, double b){
    log.info("class : " + taget.getClass().getName());
    log.info(" values : " + a + " , " + b);
}
