Currently I´m trying to integrate JWT Authentication in an existing Spring Boot Webflux Project.
As a template I used this medium article: https://medium.com/@ard333/authentication-and-authorization-using-jwt-on-spring-webflux-29b81f813e78.
If I put the Annotation @EnableWebFluxSecurity inside my WebSecurityConfig the following error occurs:
The bean 'conversionServicePostProcessor', defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/security/config/annotation/web/reactive/WebFluxSecurityConfiguration.class] and overriding is disabled.
Basicaly it´s the same error as in this post Error creating bean named `conversionServicePostProcessor` when using spring-boot-admin-server but the answers didn´t help for me and I can´t comment on answers.
In the previous post two solutions are mentioned that didn´t work for me. Removing the websocket dependency didn´t help and setting "spring.main.allow-bean-definition-overriding=true" seems to override my own Configuration, because my route /auth/login/guest is still responding 401.
Here is my WebSecurityConfiguration:
package de.thm.arsnova.frag.jetzt.backend.config;
import de.thm.arsnova.frag.jetzt.backend.security.AuthenticationManager;
import de.thm.arsnova.frag.jetzt.backend.security.SecurityContextRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.security.config.annotation.method.configuration.EnableReactiveMethodSecurity;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.server.SecurityWebFilterChain;
import reactor.core.publisher.Mono;
@Configuration
@EnableWebFluxSecurity
@EnableReactiveMethodSecurity
public class WebSecurityConfig {
private final AuthenticationManager authenticationManager;
private final SecurityContextRepository securityContextRepository;
@Autowired
public WebSecurityConfig(AuthenticationManager authenticationManager, SecurityContextRepository securityContextRepository) {
this.authenticationManager = authenticationManager;
this.securityContextRepository = securityContextRepository;
}
@Bean
public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
return http
.exceptionHandling()
.authenticationEntryPoint((swe, e) ->
Mono.fromRunnable(() -> swe.getResponse().setStatusCode(HttpStatus.UNAUTHORIZED))
).accessDeniedHandler((swe, e) ->
Mono.fromRunnable(() -> swe.getResponse().setStatusCode(HttpStatus.FORBIDDEN))
).and()
.csrf().disable()
.formLogin().disable()
.httpBasic().disable()
.authenticationManager(authenticationManager)
.securityContextRepository(securityContextRepository)
.authorizeExchange()
.pathMatchers(HttpMethod.OPTIONS).permitAll()
.pathMatchers("/auth/login/guest").permitAll()
.anyExchange().authenticated()
.and().build();
}
}
and my pom.xml
