FindByIndexNameSessionRepository “RedisConnectionFactory is required” configuration error - spring

Question

Implementing the logic of limiting active sessions for each user (number of possible sessions stored in the database, sessions in Redis), I came across the problem of configuring FindByIndexNameSessionRepository.
Due to the fact that I am injecting FindByIndexNameSessionRepository spring starts to configure the bean in the RedisHttpSessionConfiguration class, and the fields are not injected into the class via setters.
As a result, I get the error:
Caused by: java.lang.IllegalStateException: RedisConnectionFactory is required

If you remove\comment out the places where FindByIndexNameSessionRepository is used, then the RedisHttpSessionConfiguration setters are called by the "guts" of the spring when the springSessionRepositoryFilter bean is created.
If I understood correctly, then I accidentally broke the order of configuring the beans. In attempts to fix it, I tried #DependsOn, #Lazy and various frauds with moving bins to different classes of configs, changing the order of loading configs, and so on.
UPD: Add bean httpSessionEventPublisher and pom.xml

Answer 1

The main problem was that spring-boot had already configured most of the bins for me.
To resolve this problem, you must remove #EnableRedisHttpSession (#EnableWebSecurity can also be deleted), beans redisConnectionFactory and httpSessionEventPublisher, and optionally you can remove the unnecessary dependency spring-session-core
Actual config code:
#Configuration
#RequiredArgsConstructor
public class CustomConfiguration extends WebSecurityConfigurerAdapter {
private final FindByIndexNameSessionRepository<? extends Session> sessionRepository;
// ....
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/**")
.authenticated()
.and()
.formLogin()
.and()
// ....
.sessionManagement()
.sessionAuthenticationStrategy(new CustomAuthenticationStrategy(sessionRegistry(), sessionsLimitRepository));
}
#Bean
public SessionRegistry sessionRegistry() {
return new SpringSessionBackedSessionRegistry<>(sessionRepository);
}
}
