스프링 부팅에서 @EnableWebFluxSecurity를 사용할 때 오류 발생

스프링 부팅에서 @EnableWebFluxSecurity를 사용할 때 오류 발생

현재 기존 스프링 부트 웹플럭스 프로젝트에 JWT 인증을 통합하려고 합니다.템플릿으로 이 매체 기사를 사용했습니다. https://medium.com/ @ard333/인증-인증-사용-스프링-웹플럭스-29b81f813e78.
WebSecurityConfig에 Annotation @EnableWebFluxSecurity를 넣으면 다음 오류가 발생합니다.

클래스 경로 리소스 [org/springframework/security/config/annotation/web/config/WebSecurityConfiguration.class]에 정의된 'conversionServicePostProcessor'를 등록할 수 없습니다.클래스 경로 리소스 [org/springframework/security/config/annotation/web/reactive/WebFluxSecurityConfiguration.class]에 해당 이름의 빈이 이미 정의되어 있으며 재정의가 사용되지 않습니다.

기본적으로 이 게시물과 동일한 오류입니다. spring-boot-admin-server를 사용할 때 'conversionServicePostProcessor'라는 이름의 빈을 만드는 중 오류가 발생했지만 답변이 도움이 되지 않아 답변에 대해 언급할 수 없습니다.

이전 게시물에는 저에게 효과가 없는 두 가지 해결책이 언급되어 있습니다.웹 소켓 종속성을 제거해도 도움이 되지 않고 "spring.main.allow-bean-definition-definition-definition=true"를 설정하는 것이 제 자신의 구성을 재정의하는 것 같습니다. /auth/dll/dll이 여전히 401에 응답하고 있기 때문입니다.

다음은 내 웹 보안 구성입니다.

        this.authenticationManager = authenticationManager;

    }

    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
        return http
                .exceptionHandling()
                .authenticationEntryPoint((swe, e) ->
                        Mono.fromRunnable(() -> swe.getResponse().setStatusCode(HttpStatus.UNAUTHORIZED))
                ).accessDeniedHandler((swe, e) ->
                        Mono.fromRunnable(() -> swe.getResponse().setStatusCode(HttpStatus.FORBIDDEN))

                .anyExchange().authenticated()
                .and().build();
    }
}

그리고 나의 pom.xml.

테스트 속성/앱 속성에 추가할 수 있습니다.

spring.main.web-application-type=reactive

servlet과 webflux가 모두 클래스 경로에 있는 경우 이 작업이 필요하기 시작합니다.여기를 확인하십시오. https://docs.spring.io/spring-boot/docs/2.3.1.RELEASE/reference/html/spring-boot-features.html#boot-features-testing-spring-boot-applications-detecting-web-app-type

비테스트 시나리오에서는 @WesternGun에서 지정한 속성을 클래스 경로(resources/application.properties)에 추가합니다.클래스 경로에 스프링 MVC 및 스프링 웹 플럭스가 있을 때 두 번째 변환 ServicePostProcessor bean 등록을 방지하는 것 같습니다.
