AOP 사용, 어노테이션

Spring에서 AOP를 사용하면 여러가지 기능을 구현할 수 있다-
가장 간단하게 로그인 처리하는 부분을 남기려 한다-

1. pom.xml에 다음을 추가한다-

1 2 3 4 5 6 7 8 9 10 11

<!-- AOP 관련 --> <dependency> <groupid>org.aspectj</groupid> <artifactid>aspectjweaver</artifactid> <version>1.7.4</version> </dependency> <dependency> <groupid>cglib</groupid> <artifactid>cglib</artifactid> <version>2.2.2</version> </dependency>

2. Aspect.java
pointcut, advice, joinpoint 구현(?)
*req.getRequestURI()를 통해 특정 uri의 통과를 구현할 수 있다-
