AuthenticationManger in Spring security webflux

I am trying to build a custom authentication manager for my spring-webflux app. However I find that my manager is never called. My code below: 

@Bean
SecurityWebFilterChain springWebFilterChain(ServerHttpSecurity http) {
    return http
            .authorizeExchange().pathMatchers("/**").authenticated().and().httpBasic().disable()
            .securityContextRepository(webSessionServerSecurityContextRepository())
            .addFilterAfter(new AuthenticationWebFilter(bearerTokenAuthenticationManager()),
                    SecurityWebFiltersOrder.REACTOR_CONTEXT)
            .build();

}

What am I doing wrong?

Assuming you put this bean in a class annotated with @Configuration and @EnableWebFluxSecurity your problem seems that you didn't disabled csrf that is configured by default by Spring Security.

You can do that with the following:

@Bean
SecurityWebFilterChain springWebFilterChain(ServerHttpSecurity http) {
    return http
            .authorizeExchange().pathMatchers("/**").authenticated()
            .and()
            .httpBasic().disable()
            .csrf().disable() // Disable csrf
            .securityContextRepository(webSessionServerSecurityContextRepository())
            .addFilterAfter(new AuthenticationWebFilter(bearerTokenAuthenticationManager()),
                    SecurityWebFiltersOrder.REACTOR_CONTEXT)
            .build();

}

Furthermore, you have to configure correctly the AuthenticationWebFilter.

An AuthenticationWebFilter has the following dependencies:

AuthenticationWebFilter Dependencies

...most of them are provided by default as HttpBasic deps (copy and pasted from Spring Security source code):

private final ReactiveAuthenticationManagerResolver<ServerWebExchange> authenticationManagerResolver;

private ServerAuthenticationSuccessHandler authenticationSuccessHandler = new WebFilterChainServerAuthenticationSuccessHandler();

private ServerAuthenticationConverter authenticationConverter = new ServerHttpBasicAuthenticationConverter();

private ServerAuthenticationFailureHandler authenticationFailureHandler = new ServerAuthenticationEntryPointFailureHandler(new HttpBasicServerAuthenticationEntryPoint());

private ServerSecurityContextRepository securityContextRepository = NoOpServerSecurityContextRepository.getInstance(); // Stateless session

private ServerWebExchangeMatcher requiresAuthenticationMatcher = ServerWebExchangeMatchers.anyExchange();

You could set whatever you want with the setters method of AuthenticationWebFilter. An AuthenticationWebFilter has the following logic:

AuthenticationWebFilter flow

So depending of the case you have to configure one dependency or another. You could see a complete example of how Authentication and Authorization works in my repo: https://github.com/soasada/kotlin-coroutines-webflux-security (is in kotlin but for the case is the same)
