JdkSerializationRedisSerializer in Spring Boot not not change

My objects do not implement serialization and I do not want to rewrite for this. I tried to replace JdkSerializationRedisSerializer with Jackson2JsonRedisSerialize, I have tried many options but it doesn't change. What's the problem?

@EnableCaching@Configurationpublic class RedisConfig {  @Bean  public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();    redisTemplate.setConnectionFactory(redisConnectionFactory);    Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);    redisTemplate.setKeySerializer(jackson2JsonRedisSerializer);    redisTemplate.setDefaultSerializer(jackson2JsonRedisSerializer);    return redisTemplate;  }}

Error
