안녕하세요 아래와같이 prototype bean 에대해서 proxy mode 를 적용했는데.. 테스트 결과가실패하네요. 보면 prototype 이 제대로 만들어지지 않는거같은데 ComponentScan 으로 만든게아닌 임의의 AnnotationApplicationContext 를통해서 만들어서 그런가요??

    @Test
    void prototypeFInd() {
        AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(PrototypeBean.class);
        PrototypeBean bean = ac.getBean(PrototypeBean.class);
        bean.addCount();
        Assertions.assertThat(bean.getCount()).isEqualTo(1);

        PrototypeBean bean2 = ac.getBean(PrototypeBean.class);
        bean2.addCount();
        Assertions.assertThat(bean2.getCount()).isEqualTo(1);
    }


    @Test
    void singletonCLientUsePrototype() {
        AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(ClientBean.class, PrototypeBean.class);

        ClientBean clientBean1 = ac.getBean(ClientBean.class);
        int count1 = clientBean1.logic();
        Assertions.assertThat(count1).isEqualTo(1);

        ClientBean clientBean2 = ac.getBean(ClientBean.class);
        int count2 = clientBean2.logic();
        Assertions.assertThat(count2).isEqualTo(1);
    }

    @Scope("singleton")
    @RequiredArgsConstructor
    static class ClientBean {
        private final PrototypeBean prototypeBean;

        public int logic() {
            System.out.println("prototypeBean Add = " + prototypeBean);
            prototypeBean.addCount();
            return prototypeBean.getCount();
        }
    }

    @Scope(value = "prototype", proxyMode = ScopedProxyMode.TARGET_CLASS)
    static class PrototypeBean  {
        private int count = 0;

        public void addCount() {
            count++;
        }

        public int getCount() {
            return count;
        }

        @PostConstruct
        public void init() {
            System.out.println("PrototypeBean.init " + this);
        }

        @PreDestroy
        public void destroy() {
            System.out.println("PrototypeBean.destroy");
        }
    }
