Spring Boot Redis store a list of POJOs as values

I am using Redis with Spring boot. I am using String as Key and the value against it as a List of complex POJO. Below is my config:

@Configuration@EnableCaching@Slf4jpublic class RedisCacheConfig extends CachingConfigurerSupport {private static final long DEFAULT_CACHE_EXPIRES = 60;@Beanpublic RedisTemplate<String, Object> redisTemplate(final RedisConnectionFactory redisConnectionFactory) {    final RedisTemplate<String, Object> template = new RedisTemplate<>();    setRedisTemplateConfigValues(redisConnectionFactory, template);    return template;}@Beanpublic CacheManager cacheManager(final RedisConnectionFactory redisConnectionFactory) {    Map<String, RedisCacheConfiguration> cacheConfigurations = new HashMap<>();    return RedisCacheManager            .builder(redisConnectionFactory)            .cacheDefaults(createCacheConfiguration())            .withInitialCacheConfigurations(cacheConfigurations).build();}private static RedisCacheConfiguration createCacheConfiguration() {    return RedisCacheConfiguration.defaultCacheConfig()            .entryTtl(Duration.ofSeconds(DEFAULT_CACHE_EXPIRES));}private <T> void setRedisTemplateConfigValues(final RedisConnectionFactory redisConnectionFactory,                                              final RedisTemplate<String, T> template) {    template.setConnectionFactory(redisConnectionFactory);    template.setKeySerializer(new StringRedisSerializer());    template.setValueSerializer(new GenericJackson2JsonRedisSerializer());    template.setHashKeySerializer(new StringRedisSerializer());    template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());}}

The cahcing is working fine and serialization/deserialization via my app also seems to work. But when i use redis-cli, I see the below when i use the command KEYS *

1) "schools::ABC"

Now the value against ABC key should be a list of complex objects. But when I do GET "schools::ABC"

I get the value with strange characters as below:

\xac\xed\x00\x05sr\x00\x13java.util.ArrayListx\x81\xd2\x1d\x99\xc7a\x9d\x03\x00\x01I\x00\x04sizexp\x00\x00\x00\x01w\x04\x00\x00\x00\x01sr\x00(com.example. and so on....

Why is it so?

Also, I tried updating GenericJackson2JsonRedisSerializer in the config for valueSerializer to Jackson2JsonRedisSerializer. The result was no different.

Also, I tried to get the TYPE of the key, I get the result as 'String', so the list is getting stored as String.
