Class ServerHttpSecurity

java.lang.Object

org.springframework.security.config.web.server.ServerHttpSecurity

public class ServerHttpSecurity
extends java.lang.Object

A ServerHttpSecurity is similar to Spring Security's HttpSecurity but for WebFlux. It allows configuring web based security for specific http requests. By default it will be applied to all requests, but can be restricted using securityMatcher(ServerWebExchangeMatcher) or other similar methods. A minimal configuration can be found below:

 @EnableWebFluxSecurity
 public class MyMinimalSecurityConfiguration {

     @Bean
     public MapReactiveUserDetailsService userDetailsService() {
         UserDetails user = User.withDefaultPasswordEncoder()
             .username("user")
             .password("password")
             .roles("USER")
             .build();
         return new MapReactiveUserDetailsService(user);
     }
 }
 

Below is the same as our minimal configuration, but explicitly declaring the ServerHttpSecurity.

 @EnableWebFluxSecurity
 public class MyExplicitSecurityConfiguration {

     @Bean
     public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
         http
             .authorizeExchange()
               .anyExchange().authenticated()
             .and()
               .httpBasic().and()
               .formLogin();
             return http.build();
     }

     @Bean
     public MapReactiveUserDetailsService userDetailsService() {
         UserDetails user = User.withDefaultPasswordEncoder()
             .username("user")
             .password("password")
             .roles("USER")
             .build();
         return new MapReactiveUserDetailsService(user);
     }
 }
