Error: Springboot ArgumentResolver를 거치지 않는 예외

발생 상황

• 관리자 권한 검증을 위한 어노테이션과 ArgumentResolver를 구현했음에도 예외가 발생하였습니다.

• 대충 파라미터가 null로 들어오고 있는 상황으로보입니다. 디버깅 모드로 찍어봤을 때 filter까지는 잘 거치나 controller에서는 파라미터가 못들어오고 있었습니다.

 

• 아래는 구현한 코드입니다.

// controller

@GetMapping("/bills")
    public BaseResponse<AdminBills.Response> getbills(AdminBills.Request request, @Admin MemberSummary memberSummary) throws MemberException {
        AdminBills.Response allBills = adminFacade.getAllBills(request, memberSummary);
        return BaseResponse.send("조회가 완료되었습니다.", allBills);
    }

// annotation

@Target(ElementType.PARAMETER)
@Retention(RetentionPolicy.RUNTIME)
public @interface Admin {
    String value() default "";
}

// argument resolver

@Slf4j
@Component
@RequiredArgsConstructor
public class AdminArgumentResolver implements HandlerMethodArgumentResolver {

    @Override
    public boolean supportsParameter(MethodParameter parameter) {
        return parameter.hasParameterAnnotation(Admin.class);
    }

    @Override
    public Object resolveArgument(MethodParameter parameter, ModelAndViewContainer mavContainer, NativeWebRequest webRequest, WebDataBinderFactory binderFactory) throws Exception {
        HttpServletRequest httpServletRequest = (HttpServletRequest) webRequest.getNativeRequest();
        Object logined = httpServletRequest.getAttribute("logined");
        log.debug("test = {}",((MemberSummary)logined).getMemberId().toString());
        if (logined==null) {
            throw new AuthorizationServiceException("로그인이 필요한 기능입니다.");
        }
        if (((MemberSummary) logined).getRole()!= Role.ADMIN) {
            throw new AccessDeniedException("관리자 권한이 필요한 기능입니다.");
        }
        return logined;
    }
}

• 디버깅 모드에서 ArgumentResolver 브레이킹 포인트도 안먹고 로그도 안찍히는 것으로 보아 아예 ArgumentResolver를 거치지 않고 있음이 확인되었습니다.

 

발생 원인

• 어이없게도 원인은 WebMvcConfigurer에 ArgumentResolver로 등록하지 않았기 때문이었습니다.
• 어이없는 실수에 황당하지만 잊지 않기 위해서 이렇게 실수를 기록해둡니다. (내 2시간... 🥲)

 

대처

• ArgumentResolver를 등록하였습니다..

@Configuration
@RequiredArgsConstructor
public class WebConfig implements WebMvcConfigurer {

    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> resolvers) {
        resolvers.add(new LoginArgumentResolver());
        resolvers.add(new AdminArgumentResolver());
    }
    // 기타등등
}
