싱글톤이 안먹히는 거같습니다 ㅠㅠ

아래는 테스트코드고 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 ) ; MemberRepository memberRepository1 = memberService.getMemberRepository() ; MemberRepository memberRepository2 = orderService.getMemberRepository() ; System. out .println( "memberService -> memberRepository = " + memberRepository1) ; System. out .println( "orderService -> memberRepositiory = " + memberRepository2) ; System. out .println( "memberRepository = " +memberRepository) ; Assertions. assertThat (memberService.getMemberRepository()).isSameAs(memberRepository) ; Assertions. assertThat (orderService.getMemberRepository()).isSameAs(memberRepository) ; } } 아래는 AppConfig 코드입니다.. @Configuration public class AppConfig { @Bean public MemberService memberService () { System. out .println( "call AppConfig.memberService" ) ; return new MemberServiceImpl( new MemoryMemberRepository()) ; } @Bean public MemberRepository memberRepository () { System. out .println( "call AppConfig.memberRepository" ) ; return new MemoryMemberRepository() ; } @Bean public OrderService orderService () { System. out .println( "call AppConfig.orderService" ) ; return new OrderServiceImpl( new MemoryMemberRepository() , new RateDiscountpolicy()) ; } @Bean public DiscountPolicy discountPolicy () { return new RateDiscountpolicy() ; } }
