Spring Boot 프로젝트에 메서드 기반 보안을 추가하려면 어떻게 해야 합니까?

Spring Boot 프로젝트에 메서드 기반 보안을 추가하려면 어떻게 해야 합니까?

스프링 부트 프로젝트에 메서드 기반 보안을 추가하고 싶습니다.

내가 필요한 것은 단지 추가하는 것뿐인 것처럼 보였습니다.PermissionEvaluator그리고.MethodSecurityExpressionHandler콩, 주석 달기 내 것WebSecurityConfigurerAdapter와 함께@EnableGlobalMethodSecurity(prePostEnabled = true)및 사용 방법@PreAuthorize("isAuthenticated() and hasPermission(#param, 'somePermissionName')").

하지만 a를 추가한 후에.PermissionEvaluator콩을

@Bean
public PermissionEvaluator permissionEvaluator() {
    HelloPermissionEvaluator bean = new HelloPermissionEvaluator();
    return bean;
}

나는 이해합니다.IllegalArgumentException"기본 서블릿 처리를 구성하려면 서블릿 컨텍스트가 필요합니다."

제가 웹에서 찾을 수 있는 것은 jUnit 테스트와 관련된 것뿐입니다.이 예외가 발생하는 이유는 무엇입니까?제가 무엇을 빠뜨리고 있나요?서블릿 컨텍스트 빈을 추가해야 합니까? 추가할 경우 어떻게 해야 합니까?

요구사항은 Gradle, Spring Boot 및 Java 구성(XML 구성 대신)최소 및 전체 소스는 다음과 같습니다.

다음을 입력해 보십시오.PermissionEvaluator별채로@Configuration수업. 당신은 그것을 강제로 인스턴스화하는 것처럼 보입니다.ServletContext준비되었습니다(스프링 보안 필터를 매우 일찍 생성해야 이러한 작업이 가능합니다).

유사한 문제가 발생했습니다.식 핸들러에서 사용자 지정 권한 평가자를 구성하려는 경우 다음과 같은 작업을 수행할 수 있습니다.

public class SecurityPermissionEvaluator implements PermissionEvaluator 
    {
    //A is a spring managed bean on which permission evaluator depends
    private A a;

    @Autowired
    public  SecurityPermissionEvaluator(A a){
        this.a = a;
    }
    @Override
    public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) {

        return false;
    }
}

then

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends GlobalMethodSecurityConfiguration {

    @Autowired private A a;

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        DefaultMethodSecurityExpressionHandler expressionHandler =
                new DefaultMethodSecurityExpressionHandler();
        PermissionEvaluator permissionEvaluator = new SecurityPermissionEvaluator(a);
        expressionHandler.setPermissionEvaluator(permissionEvaluator);
        return expressionHandler;
    }

}

권한 평가자를 명시적으로 사용하려면 위의 작업과 함께 Daveie가 제안한 대로 on config 파일에 권한 평가자 bean을 정의합니다.
