I have a keycloak instance running and that i access normally. All keycloak endpoints are running as they should. I tried connecting my Spring app to keycloak through the following
App.yaml :
(https://i.sstatic.net/tLXfhxyf.png)
SecurityConfig:
``@Configuration
@EnableWebSecurity
public class SecurityConfig {
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.csrf(csrf -> csrf.disable())
.authorizeHttpRequests(auth -> auth
.requestMatchers("/public/**", "/oauth2/**", "/login/**").permitAll()
.anyRequest().authenticated()
)
.oauth2Login(oauth2 -> oauth2
.loginPage("/oauth2/authorization/keycloak")
.defaultSuccessUrl("/", true)
)
.logout(logout -> logout
.logoutSuccessUrl("/")
.permitAll()
);
return http.build();
}
@Bean
protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
return new NullAuthenticatedSessionStrategy();
}
@Bean
public OAuth2AuthorizedClientManager authorizedClientManager(
ClientRegistrationRepository clientRegistrationRepository,
OAuth2AuthorizedClientRepository authorizedClientRepository) {
OAuth2AuthorizedClientProvider authorizedClientProvider =
OAuth2AuthorizedClientProviderBuilder.builder()
.authorizationCode()
.refreshToken()
.build();
DefaultOAuth2AuthorizedClientManager authorizedClientManager =
new DefaultOAuth2AuthorizedClientManager(
clientRegistrationRepository, authorizedClientRepository);
authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);
return authorizedClientManager;
}
}``
KeycloakConfig:
@Configuration
public class KeycloakConfig {
@Value("${spring.security.oauth2.client.provider.keycloak.issuer-uri}")
private String serverUrl;
@Value("${spring.security.oauth2.client.registration.keycloak.client-id}")
private String clientId;
@Value("${spring.security.oauth2.client.registration.keycloak.client-secret}")
private String clientSecret;
@Bean
public Keycloak keycloak() {
return KeycloakBuilder.builder()
.serverUrl("http://localhost:8080") // Remove realm from server URL
.realm("FlowUsers") // Hardcode realm or make it configurable if needed
.clientId(clientId)
.clientSecret(clientSecret)
.grantType("client_credentials")
.build();
}
}`
Yet i keep getting this error whenever I run the Spring app :
‘clientRegistrationRepository’ threw exception with message: Unable to resolve Configuration with the provided Issuer of "http://localhost:8080/realms/FlowUsers"
I tested Keycloak endpoints and they are returning the correct outputs, Double-checked every url in my yaml.
