TokenRelayGatewayFilterFactory protecting all URL's - spring-cloud

Question

I have a project https://github.com/ndrone/sample-gateway-oauth2login/tree/feature/allowAllToHealth That I am trying to allow specific URL's open to anyone that request it. In this case, it is the health endpoint of Actuator while protect all other Actuator endpoints. What I am finding is that the TokenRelayGatewayFilterFactory is being applied to all routes when though it is only set to be applied to one route. Not sure what I got wrong.
SecurityConfig in the Resource Service
#EnableWebFluxSecurity
public class SecurityConfig {
#Bean
SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) throws Exception {
http.authorizeExchange().pathMatchers("/manage/health").permitAll();
http
.authorizeExchange()
.pathMatchers("/resource", "/manage/**").hasAuthority("SCOPE_resource.read")
.anyExchange().authenticated()
.and()
.oauth2ResourceServer()
.jwt();
return http.build();
}
}
Gateway Routes
#Controller
#SpringBootApplication
public class GatewayApplication {
#Autowired
private TokenRelayGatewayFilterFactory filterFactory;
#Bean
public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
//#formatter:off
return builder.routes()
.route("resource-health", r -> r.path("/resource/manage/health")
.filters(f -> f.stripPrefix(1))
.uri("http://localhost:9000"))
.route("resource-actuator-protected", r -> r.path("/resource/manage/**")
.filters(f -> f.stripPrefix(1).filter(filterFactory.apply()))
.uri("http://localhost:9000"))
.route("resource", r -> r.path("/resource")
.filters(f -> f.filter(filterFactory.apply()))
.uri("http://localhost:9000"))
.build();
//#formatter:on
}
#GetMapping("/")
public String index(Model model,
#RegisteredOAuth2AuthorizedClient OAuth2AuthorizedClient authorizedClient,
#AuthenticationPrincipal OAuth2User oauth2User) {
model.addAttribute("userName", oauth2User.getName());
model.addAttribute("clientName", authorizedClient.getClientRegistration().getClientName());
model.addAttribute("userAttributes", oauth2User.getAttributes());
return "index";
}
public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);
}
}

Since I didn't have a spring security configuration detailed out in the gateway. Spring Security protected all urls. Digging into the sample more and the source of their fork from jgrandja I needed to add the following.
/**
* This code duplicates {#link org.springframework.boot.actuate.autoconfigure.security.reactive.ReactiveManagementWebSecurityAutoConfiguration}
* and enhances with oauth2Login() specific configuration
*
* and with changes defined by jgrandja #see OAuth
*

#Configuration
#ConditionalOnClass({ EnableWebFluxSecurity.class, WebFilterChainProxy.class })
#ConditionalOnMissingBean({ SecurityWebFilterChain.class, WebFilterChainProxy.class })
#ConditionalOnWebApplication(type = ConditionalOnWebApplication.Type.REACTIVE)
#AutoConfigureBefore(ReactiveSecurityAutoConfiguration.class)
#AutoConfigureAfter({ HealthEndpointAutoConfiguration.class,
InfoEndpointAutoConfiguration.class, WebEndpointAutoConfiguration.class,
ReactiveOAuth2ClientAutoConfiguration.class,
ReactiveOAuth2ResourceServerAutoConfiguration.class })
class SecurityConfig {
#Bean
SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
// #formatter:off
// gateway actuator
http.authorizeExchange()
.matchers(EndpointRequest.to(HealthEndpoint.class, InfoEndpoint.class)).permitAll();
// gateway resource actuator
http.authorizeExchange().pathMatchers("/manage/health").permitAll();
return http.authorizeExchange()
.anyExchange().authenticated()
.and()
.oauth2Login()
.and()
.exceptionHandling()
// NOTE:
// This configuration is needed to perform the auto-redirect to UAA for authentication.
.authenticationEntryPoint(new RedirectServerAuthenticationEntryPoint("/oauth2/authorization/login-client"))
.and()
.build();
// #formatter:on
}
}
