How to exclude a path from authentication in a spring based reactive application?

问题

In a non reactive spring application I would usually create a configuration class, extend WebSecurityConfigurerAdapter and configure the WebSecurity like such:

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/pathToIgnore");
}

How can I do the equivalent in a reactive application?

In your security config class which you have annotated with @EnableWebFluxSecurity and @EnableReactiveMethodSecurity, register a bean as follows:

@Bean
public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
    return http.authorizeExchange()
        .pathMatchers("/pathToIgnore")
        .permitAll()
        .anyExchange()
        .authenticated()
        .and()
        .formLogin()
        .and()
        .csrf()
        .disable()
        .build();
}

In this config, pathMatchers("/pathToIgnore").permitAll() would configure it to allow the paths matched to be excluded from auth and anyExchange().authenticated() would configure it to authenticate all other requests.
