Spring-AOP 슬라이스 + Aspectj 프레임 사용

AOP 슬라이스 개발에는 Aspectj 프레임워크를 사용합니다.
먼저 두 개의 Jar 패키지를 가져와야 합니다. 1.aspectjrt.jar 2. aspectjweaver-XXX.jar
Aspectj에서 지원하는 5가지 메모:

@Before: 사전 통지, 방법이 실행되기 전에 실행

@After: 백업 알림, 방법이 실행된 후에 실행

@AfterReturning: 알림을 되돌려주고 방법이 결과를 되돌려준 후에 실행

@AfterThrowing: 이상 알림, 방법이 이상을 던진 후

@Around: 알림을 둘러싸고 실행

다음은 두 가지 방식으로 개발할 것이다.
형식 1: Spring, 슬라이스:Audience Advice 클래스와 메모 결합

@Aspect
public class AudienceAdvice {
    /** * 1> execution() :         * 2> * *..UserService.*(..):       * (1) * :     -->   :public  public void * (2) *. :          * (3) .UserService :      UserService     * (4) .* :       * (5) (..) :          * *   :     UserServiceImpl     ,   AOP   * 3>          ,              , *                 *   : init()      after()         * */
    @Pointcut("execution(* *..UserService.*(..))")
    public void init(){};

    /** *    */
    @After("init()")
    public void after(){
        System.out.println("after");
    }


    /** *    */
    @Before("init()")
    public void before(){
        System.out.println("before");
    }

    /** *    */
    @Around("init()")
    public void around(ProceedingJoinPoint jp){
        System.out.println("before");
        try {
            //    
            jp.proceed();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        System.out.println("after");
    }
}

UserServiceImpl 클래스

public class UserServiceImpl implements UserService{
    @Override
    public void save() {

    }
}

Test 섹션

public class UserServiceTest {  
    @Test
    public void saveTest(){
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("spr*.xml");
        UserService userDao = 
                applicationContext.getBean("userServiceImpl", UserService.class);
        userDao.save();
        applicationContext.close();
    }
}

형식2: XML 구성Aspectj를 사용하여 Spring 슬라이스와 결합:Audience Advice

public class AudienceAdvice {

    public void init(){};

    /** *    */
    public void after(){
        System.out.println("after");
    }


    /** *    */
    public void before(){
        System.out.println("before");
    }

    /** *    */
    public void around(ProceedingJoinPoint jp){
        System.out.println("before");
        try {
            jp.proceed();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        System.out.println("after");
    }

}

UserServiceImpl 서비스 계층:

public class UserServiceImpl implements UserService{

    public UserServiceImpl() {
        System.out.println("   ");
    }

    @Override
    public void save() {
        System.out.println("save");
    }

}

테스트 섹션:

public class UserServiceTest {  
    @Test
    public void saveTest(){
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("spr*.xml");
        UserService userDao = 
                applicationContext.getBean("userServiceImpl", UserService.class);
