Simplify Configuring Realm Name for WebFlux Applications

[tensberg]

Summary

I'd like to be able to change the HTTP BASIC Realm configured by the WebFlux ServerHttpSecurity http.httpBasic(). It looks to me like there is no way to get at the underlying HttpBasicSpec.entryPoint to change the default.

Actual Behavior

ServerHttpSecurity http.httpBasic() always uses the default realm Realm.

Expected Behavior

Add API ServerHttpSecurity http.httpBasic().realmName("myRealm") similar to HttpSecurity to change the realm.

Configuration

@Bean
    public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        http
            .authorizeExchange()
                .anyExchange().authenticated()
                .and()
            .httpBasic()
        return http.build();
    }

Version

Spring Boot 2.1.1.RELEASE
Spring Security 5.1.2.RELEASE
