Checking username and password in Keycloak and roles in local database - spring-security

Question

I am trying to use keycloak for authentification by username and password. But at the same time I need to check, if the user from local database with the same name as user in keycloak has some roles in local database, PostgreSQL for example. The problem, I don't need keycloak roles, but need to check roles in local database.
Now my SecurityConfig which extends from KeycloakWebSecurityConfigurerAdapter looks like this:
#KeycloakConfiguration
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {
#Autowired
RealmConfig realmConfig;
#Autowired
AuthConfig authConfig;
#Override
protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
return new NullAuthenticatedSessionStrategy();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
SimpleAuthorityMapper grantedAuthorityMapper = new SimpleAuthorityMapper();
grantedAuthorityMapper.setPrefix("ROLE_");
KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
auth.authenticationProvider(keycloakAuthenticationProvider);
}
#Bean
public KeycloakConfigResolver keycloakConfigResolver() {
return new KeycloakSpringBootConfigResolver();
}
#Override
protected void configure(HttpSecurity http) throws Exception {
super.configure(http);
//roles from local database
String roles = String.join(",", authConfig.roles());
http
.csrf().disable()
.authorizeRequests()
.antMatchers( "/api/gui*")
.hasAnyRole(roles)
.anyRequest()
.permitAll()
.and()
.exceptionHandling().accessDeniedHandler(accessDeniedHandler())
.and().logout().logoutUrl("/api/logout").logoutSuccessUrl("/api/").deleteCookies("OAuth_Token_Request_State", "JSESSIONID").invalidateHttpSession(true);
}
}
But hasAnyRoles check roles from keycloak users. Is there any way to make hasAnyRoles checking roles from local database user?
