프록시팩토리 - 적용 2

이번에는 인터페이스가 없고, 구체 클래스만 있는 v2 애플리케이션에 LogTrace 기능을 프록시 팩토리를
통해서 프록시를 만들어 적용해보자.

 

Advice는 동일하니 Config만 새로 만들면 된다.

 

 

1. Config

---

@Slf4j
@Configuration
public class ProxyFactoryConfigV2 {

    @Bean
    public OrderControllerV2 orderControllerV2(LogTrace logTrace){
        OrderControllerV2 orderController = new OrderControllerV2(orderServiceV2(logTrace));
        ProxyFactory proxyFactory = new ProxyFactory(orderController);
        proxyFactory.addAdvisor(getAdvisor(logTrace));
        OrderControllerV2 proxy = (OrderControllerV2) proxyFactory.getProxy();
        log.info("Proxyfactory proxy={}, target={}", proxy.getClass(), orderController.getClass());

        return proxy;
    }

    @Bean
    public OrderServiceV2 orderServiceV2(LogTrace logTrace){
        OrderServiceV2 orderService = new OrderServiceV2(orderRepositoryV2(logTrace));
        ProxyFactory proxyFactory = new ProxyFactory(orderService);
        proxyFactory.addAdvisor(getAdvisor(logTrace));
        OrderServiceV2 proxy = (OrderServiceV2) proxyFactory.getProxy();
        log.info("Proxyfactory proxy={}, target={}", proxy.getClass(), orderService.getClass());

        return proxy;
    }
    @Bean
    public OrderRepositoryV2 orderRepositoryV2(LogTrace logTrace){
        OrderRepositoryV2 orderRepository = new OrderRepositoryV2();

        ProxyFactory proxyFactory = new ProxyFactory(orderRepository);
        proxyFactory.addAdvisor(getAdvisor(logTrace));
        OrderRepositoryV2 proxy = (OrderRepositoryV2) proxyFactory.getProxy();

        log.info("Proxyfactory proxy={}, target={}", proxy.getClass(), orderRepository.getClass());
        return proxy;
    }

    private Advisor getAdvisor(LogTrace logTrace) {
        //point cut
        NameMatchMethodPointcut pointcut = new NameMatchMethodPointcut();
        pointcut.setMappedNames("request*", "order*", "save*");

        //advice
        LogTraceAdvice advice = new LogTraceAdvice(logTrace);

        return new DefaultPointcutAdvisor(pointcut, advice);

    }
}

 

 

2. 실행

---

@Import(ProxyFactoryConfigV2.class)
@SpringBootApplication(scanBasePackages = "hello.proxy.app") //주의
public class ProxyApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProxyApplication.class, args);
    }

    @Bean
    public LogTrace logTrace(){
        return new ThreadLocalLogTrace();
    }

}

Proxyfactory proxy=class hello.proxy.app.v2.OrderRepositoryV2$$EnhancerBySpringCGLIB$$90482bf4, target=class hello.proxy.app.v2.OrderRepositoryV2
Proxyfactory proxy=class hello.proxy.app.v2.OrderServiceV2$$EnhancerBySpringCGLIB$$e4985a17, target=class hello.proxy.app.v2.OrderServiceV2
Proxyfactory proxy=class hello.proxy.app.v2.OrderControllerV2$$EnhancerBySpringCGLIB$$924f52aa, target=class hello.proxy.app.v2.OrderControllerV2

• V2 애플리케이션은 인터페이스가 없고 구체 클래스만 있기 때문에 프록시 팩토리가 CGLIB을 적용한다.
• 애플리케이션 로딩 로그를 통해서 CGLIB 프록시가 적용된 것을 확인할 수 있다.
