    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory(redisProperties.getHost(), redisProperties.getPort());
    }

    @Bean
    public RedisTemplate<?, ?> redisTemplate() {
        RedisTemplate<byte[], byte[]> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory());
        return redisTemplate;
    }
}
