[Spring Framework] AOP 활용하기~!

1. POM파일

<dependency>

<groupId>org.springframework</groupId>

    <artifactId>spring-aop</artifactId>

    <version>${org.springframework-version}</version>

       </dependency>

<dependency>

<groupId>org.aspectj</groupId>

   <artifactId>aspectjrt</artifactId>

   <version>${org.aspectj-version}</version>

      </dependency>

      <dependency>

   <groupId>org.aspectj</groupId>

   <artifactId>aspectjweaver</artifactId>

   <version>${org.aspectj-version}</version>

      </dependency>

2. Class 파일 (해당 클래스에 구현된 모든 함수에서 User를 리턴하는 함수에 패스워드를 null로 해주는 것 구현)

@Aspect

public class UserAspect {

@Around (value = "execution (public 패키지.User 패키지.UserDaoImpl.*(..))")

public User removeUserPasswordMethod (final ProceedingJoinPoint joinPoint) {

try {

final User user = (User) joinPoint.proceed();

if (user != null) {

user.setPassword(null);

}//end if

return user;

} catch (Throwable e) {

e.printStackTrace();

}//end try/catch

return null;

}//end removeUserPasswordMethod Method

3. 설정파일 설정
