FindByIndexNameSessionRepository 配置错误“RedisConnectionFactory is required”

实现限制每个用户活动会话的逻辑（会话数存储在数据库中，会话本身在 Redis 中），我遇到了一个配置问题FindByIndexNameSessionRepository。

由于我注入的事实，FindByIndexNameSessionRepositoryspring 开始在RedisHttpSessionConfiguration类中配置 bean ，而不通过 setter 将字段注入自身。

结果，我收到一个错误：

配置代码：

@EnableRedisHttpSession
@EnableWebSecurity
@Configuration
@RequiredArgsConstructor
public class CustomConfiguration extends WebSecurityConfigurerAdapter {
    private final FindByIndexNameSessionRepository sessionRepository;    
    // ....

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/**")
                .authenticated()
                .and()
            .formLogin()
                .and()
            // ....
            .sessionManagement()
                .sessionAuthenticationStrategy(new CustomAuthenticationStrategy(sessionRegistry(), sessionsLimitRepository));
    }

    @Bean
    public SpringSessionBackedSessionRegistry sessionRegistry() {
        return new SpringSessionBackedSessionRegistry(sessionRepository);
    }

    @Bean
    public LettuceConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory(new RedisStandaloneConfiguration("server", 6379));
    }

    @Bean
    public HttpSessionEventPublisher httpSessionEventPublisher() {
        return new HttpSessionEventPublisher();
   }
}

如果删除\注释掉使用它的地方FindByIndexNameSessionRepository，那么RedisHttpSessionConfiguration设置器会在创建 bean 时由 spring 的“胆量”调用springSessionRepositoryFilter。

如果我理解正确，那么我不小心打破了配置bean的顺序。为了解决这个问题，我尝试@DependsOn了各种@Lazy欺诈行为，例如将 bin 移动到不同的配置类、更改加载配置的顺序等等。

UPD 1：添加了 bean httpSessionEventPublisher
UPD 2：添加了 pom.xml
