我正在使用Spring Security和WebFlux的http基本身份验证。尽管通过创建一个实现WebFluxConfigurer的类来添加corsMap，禁用cors并添加corsMap，但我仍然无法通过我的Angular应用程序发送任何请求。我添加了两个安全配置文件，代码如下所示：用于配置一般安全性

@Configuration
@EnableReactiveMethodSecurity
@EnableWebFluxSecurity
public class SecurityConfig {
    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http){
        return http
                .cors().and().csrf().disable()
                .authorizeExchange()
                .anyExchange()
                .authenticated()
                .and()
                .httpBasic()
                .and()
                .build();
    }
    @Bean
    public ReactiveAuthenticationManager authenticationManager(ReactiveUserDetailsService userDetailsService,
                                                               PasswordEncoder passwordEncoder){
        UserDetailsRepositoryReactiveAuthenticationManager manager = new UserDetailsRepositoryReactiveAuthenticationManager(userDetailsService);
        manager.setPasswordEncoder(passwordEncoder);
        return manager;
    }
    @Bean
    public ReactiveAuthenticationManager reactiveAuthenticationManager(ReactiveUserDetailsService userDetailsService,
                                                               PasswordEncoder passwordEncoder) {
        return authentication ->
            userDetailsService.findByUsername(authentication.getPrincipal().toString())
                    .switchIfEmpty(Mono.empty())
                    .flatMap(user -> {
                        final String username = authentication.getPrincipal().toString();
                        final CharSequence rawPassword = authentication.getCredentials().toString();
                        if (passwordEncoder.matches(rawPassword, user.getPassword())) {
                            System.out.println("User has been authentication " + username);
                            return Mono.just(new UsernamePasswordAuthenticationToken(username, user.getPassword(), user.getAuthorities()));
                        }
                        return Mono.just(new UsernamePasswordAuthenticationToken(username, authentication.getAuthorities()));
                    });

    }
        @Bean
    public PasswordEncoder noPasswordEncoder(){
        return NoOpPasswordEncoder.getInstance();
    }
}

对于配置CORS：

@Configuration
@EnableWebFlux
public class WebConfig implements WebFluxConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("localhost:4200")
                .allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
                .allowedHeaders("Access-Control-Allow-Origin", "Authorization", "Content-Type");
    }
}

错误消息：

Access to XMLHttpRequest at 'http://localhost:8080/course/my-courses' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
error: ProgressEvent {isTrusted: true, lengthComputable: false, loaded: 0, total: 0, type: 'error', …}

name: "HttpErrorResponse"

status: 0
statusText: "Unknown Error"

我在这里做错了什么？
