인프런 커뮤니티 질문&답변

안녕하세요..!

강의내용에 따르면 

class hello.core.AppConfig 이렇게 출력이 안나와야하는데,,

저는 예상과 같게

이렇게 출력이 됩니다..

뭐가 문제일까요..?????????

코드는 제가 친것을 지우고 강의자료 복사붙여넣기 한 결과입니다..

package hello.core.singleton;

import hello.core.AppConfig;
import hello.core.member.MemberRepository;
import hello.core.member.MemberServiceImpl;
import hello.core.order.OrderServiceImpl;
import org.junit.jupiter.api.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import static org.assertj.core.api.Assertions.*;
public class ConfigurationSingletonTest {
    @Test
    void configurationTest() {
        ApplicationContext ac = new
                AnnotationConfigApplicationContext(AppConfig.class);
        MemberServiceImpl memberService = ac.getBean("memberService",
                MemberServiceImpl.class);
        OrderServiceImpl orderService = ac.getBean("orderService",
                OrderServiceImpl.class);
        MemberRepository memberRepository = ac.getBean("memberRepository",
                MemberRepository.class);
        //모두 같은 인스턴스를 참고하고 있다.
        System.out.println("memberService -> memberRepository = " +
                memberService.getMemberRepository());
        System.out.println("orderService -> memberRepository = " +
                orderService.getMemberRepository());
        System.out.println("memberRepository = " + memberRepository);
        //모두 같은 인스턴스를 참고하고 있다.
        assertThat(memberService.getMemberRepository()).isSameAs(memberRepository);

        assertThat(orderService.getMemberRepository()).isSameAs(memberRepository);

    }

    @Test
    void configurationDeep() {
        ApplicationContext ac = new
                AnnotationConfigApplicationContext(AppConfig.class);
        //AppConfig도 스프링 빈으로 등록된다.
        AppConfig bean = ac.getBean(AppConfig.class);

        System.out.println("bean = " + bean.getClass());
        //출력: bean = class hello.core.AppConfig$$EnhancerBySpringCGLIB$$bd479d70
    }
}
