[keycloak-user] There is already a httpSessionManager

[Calixto Meleán]

I’m doing a simple tutorial with SpringBoot 2.1.0 and KeyCloack 4.5.0. When I start the app, I am getting the following error:

org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'httpSessionManager' defined in class path resource [com/example/demo/configuration/SecurityConfig.class]: Cannot register bean definition [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=securityConfig; factoryMethodName=httpSessionManager; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [com/example/demo/configuration/SecurityConfig.class]] for bean 'httpSessionManager': There is already [Generic bean: class [org.keycloak.adapters.springsecurity.management.HttpSessionManager]; scope=singleton; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in URL [jar:file:/Users/bigcat/.m!
2/repository/org/keycloak/keycloak-spring-security-adapter/4.5.0.Final/keycloak-spring-security-adapter-4.5.0.Final.jar!/org/keycloak/adapters/springsecurity/management/HttpSessionManager.class]] bound.

Relevant maven dependencies I have are:

<dependency>
  <groupId>org.keycloak</groupId>
  <artifactId>keycloak-spring-boot-starter</artifactId>
  <version>${keycloak.version}</version>
</dependency>

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-security</artifactId>
</dependency>

SecurityConfig.class is:

@KeycloakConfiguration
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {

   @Bean
   public KeycloakConfigResolver KeycloakConfigResolver() {
       return new KeycloakSpringBootConfigResolver();
   }

   /**
    * Registers the KeycloakAuthenticationProvider with the authentication manager.
    */
   @Autowired
   public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
       auth.authenticationProvider(keycloakAuthenticationProvider());
   }

   /**
    * Defines the session authentication strategy.
    */
   @Bean
   @Override
   protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
       return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
   }

   @Override
   protected void configure(HttpSecurity http) throws Exception
   {
       super.configure(http);
       http
               .authorizeRequests()
               .antMatchers("/customers*").hasRole("pharmacist")
               .anyRequest().permitAll();
   }
}


Appreciate any help. Thanks
