[질문 내용]
최근 복습을 진행하며 자동 빈 등록, 수동 빈 등록에 관해 스스로 이것저것 해보다가 궁금한게 있어 질문 드립니다.

 

우선 AppConfig.class입니다.

package com.example.asdfsadf.test;

@Configuration
public class AppConfig {

    private OrderService orderService;

    @Autowired
    public AppConfig(OrderService orderService) {
        this.orderService = orderService;
    }

    @Bean
    public OrderRepository orderRepository() {
        return new MemoryOrderRepository();
    }
}

AppConfig.class에는 OrderService를 생성자 주입을 받고 있고, 수동으로 OrderRepository를 빈으로 등록하였습니다.

 

그리고 같은 패키지에 AppScanConfig.class를 두었습니다.

package com.example.asdfsadf.test;

@ComponentScan
public class AppScanConfig {
}

 

마지막으로 OrderService는 AppScanConfig에 의해 자동 빈 주입 받습니다.

@Component
public class OrderServiceImpl implements OrderService {

    private final OrderRepository orderRepository;

    public OrderServiceImpl(OrderRepository orderRepository) {
        this.orderRepository = orderRepository;
    }
}

 

이때, 다음과 같이 단순히 AppScanConfig 정보를 바탕으로 컨테이너로 생성하도록 테스트 하였습니다.

class appConfigTest {

    @Test
    public void test() {
        AnnotationConfigApplicationContext ac 
                = new AnnotationConfigApplicationContext(AppScanConfig.class);
    }
}

결과는 다음과 같은 오류가 발생했습니다.

근데 AppConfig에서 OrderService를 생성자 주입이 아닌 필드 주입으로 하면 오류가 발생하지 않고 정상적으로 빈 등록이 완료되었습니다. (필드 주입으로 하더라도 AppConfig의 이름을 zAppConfig로 해서 패키지의 가장 아래에 놓이게 해도 에러가 발생합니다.)

 

제가 생각한 오류 원인은 이렇습니다.

  1. AppScanConfig를 설정 파일로 지정했기 때문에 가장 먼저 빈으로 등록

  2. 패키지의 가장 위에 있는 @Component 클래스인 AppConfig를 빈으로 등록

  3. AppConfig를 빈으로 등록하는 과정에서 생성자 주입으로 OrderService를 빈으로 등록하려함

  4. OrderService를 빈으로 등록하려고 봤더니 OrderRepository를 의존하고 있어서 OrderRepository를 빈으로 등록하려함

  5. OrderRepository를 빈으로 등록하기 위해서 AppConfig에 접근

  6. AppConfig는 OrderService를 의존하고 있어서 OrderService를 빈으로 등록하기 위해 이동...

    -> 순환 참조 문제

라고 생각했습니다.

 

하지만 OrderRepository만 빈으로 등록하면 될 문제 같은데 위 상황에서 왜 되지 않는건지 명확하게 이해가 가지 않아서 질문드립니다! 어떤 문제 때문에 에러가 발생하는 걸까요 ??

안녕하세요. 괭이님

AppConfig를 생성하기 위해서는 OrderService가 필요합니다.

OrderService를 생성하기 위해서는 OrderRepository가 필요합니다.

OrderRepository를 생성하기 위해서는 AppConfig가 먼저 생성되어야 합니다.

이렇게 되어서 순환 사이클이 발생한 것입니다.

이 문제를 해결하는 가장 단순한 방법은 RepositoryConfig를 만들고 그 안에서 OrderRepository를 빈으로 등록하시면 됩니다.

감사합니다.
