Okay, this chapter is titled Securing Your App with Spring Boot, yet we have spent a fair amount of time... NOT securing our app! That is about to change. Thanks to this little bit of restructuring, we can move forward with locking things down as desired.

    @EnableWebFluxSecurity 
    public class SecurityConfiguration { 
 
      @Bean 
      SecurityWebFilterChain springWebFilterChain(HttpSecurity http) { 
        return http

The preceding security policy can be defined as follows:

• @EnableWebFluxSecurity activates the Spring WebFlux security filters needed to secure our application
• @Bean marks...
