/**
 * Add this annotation to a {@code Configuration} class to have Spring Security WebFlux
 * support added. User's can then create one or more {@link ServerHttpSecurity}
 * {@code Bean} instances.
 *
 * A minimal configuration can be found below:
 *
 * <pre class="code">
 * &#064;Configuration
 * &#064;EnableWebFluxSecurity
 * public class MyMinimalSecurityConfiguration {
 *
 *     &#064;Bean
 *     public MapReactiveUserDetailsService userDetailsService() {
 *          UserDetails user = User.withDefaultPasswordEncoder()
 *               .username("user")
 *               .password("password")
 *               .roles("USER")
 *               .build();
 *          return new MapReactiveUserDetailsService(user);
 *     }
 * }
 * </pre>
 *
 * Below is the same as our minimal configuration, but explicitly declaring the
 * {@code ServerHttpSecurity}.
 *
 * <pre class="code">
 * &#064;Configuration
 * &#064;EnableWebFluxSecurity
 * public class MyExplicitSecurityConfiguration {
 *     &#064;Bean
 *     public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
 *          http
 *               .authorizeExchange()
 *                    .anyExchange().authenticated()
 *                         .and()
 *                    .httpBasic().and()
 *                    .formLogin();
 *          return http.build();
 *     }
 *
 *     &#064;Bean
 *     public MapReactiveUserDetailsService userDetailsService() {
 *          UserDetails user = User.withDefaultPasswordEncoder()
 *               .username("user")
 *               .password("password")
 *               .roles("USER")
 *               .build();
 *          return new MapReactiveUserDetailsService(user);
 *     }
 * }
 * </pre>
