해결 방법

기존 내 설정 파일 pom.xml을 확인해보니 아래와 같이 설정되어 있었다. AOP 구현을 위해서는 AspectJ 라이브러이와 함께 AspectJWeaver 라이브러리도 같이 사용된다. "AspectJ Weaver"는 aspect의 정보를 바탕으로 aspect를 구성한 코드를 생성하는데 필요한 유틸리티 프로그램이다.

기존 pom.xml

		<!-- AspectJ -->
		<dependency>
			<groupId>org.aspectj</groupId>
			<artifactId>aspectjrt</artifactId>
			<version>${org.aspectj-version}</version>
		</dependency>

AspectJ Weaver Dependency 추가하여 해결!

 		<!-- AspectJ -->
		<dependency>
			<groupId>org.aspectj</groupId>
			<artifactId>aspectjrt</artifactId>
			<version>${org.aspectj-version}</version>
		</dependency>
 
 		<!-- AspectJ Weaver-->
		<!-- 스프링 AOP 처리가 된 객체를 생성할 때 AspectJ Weaver라이브러리의 도움을을 받아 동작함 -->
