This is due to new behaviour in Spring Boot 2.1 surrounding duplicate definition of beans.
Release note:
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.1-Relea...
Overriding beans is required to follow the current documentation on integrating Keycloak
into your Spring Boot app.
You can reenable this behaviour by including the following in your application.yml:
spring:
main:
allow-bean-definition-overriding: true
Or spring.main.allow-bean-definition-overriding=true in your application.properties.
Hope this helps.
Regards,
Zed

I’m doing a simple tutorial with SpringBoot 2.1.0 and KeyCloack 4.5.0. When I start my
app, I am getting the error below. It’s like the session manager bean is being registered
more than once.

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
