问从reids读取数据时有一个ClassCastException

EN

There is a ClassCastException when reading data from reids, but the actual quantity type is correct, and this happens for a period of time. After restarting the service, the problem is solved, but it appears again in some days!
``` @Configuration

public class RedisConfig {

    /**

     * FastJson序列化
     *
     * @param factory
     * @return
     * @author Hes
     */
    @Bean
    public RedisTemplate fastJsonRedisTemplate(RedisConnectionFactory factory) throws Exception {
        RedisTemplate redisTemplate = new RedisTemplate();
        redisTemplate.setConnectionFactory(factory);
        FastJsonSerializer serializer = new FastJsonSerializer<Object>(Object.class);
        redisTemplate.setValueSerializer(serializer);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    /**

     * fst序列化
     *
     * @param factory
     * @return
     * @author Hes
     */
    @Bean
    public RedisTemplate<String, Object> fstRedisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
        FSTSerializer<Object> serializer = new FSTSerializer<>();
        redisTemplate.setDefaultSerializer(serializer);
        redisTemplate.setKeySerializer(RedisSerializer.string());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

    List<DataMap> datas = RedisKit.getMapValue(CACHE_AREA, orgNo);

    return datas;

}

    T t = null;

    if (StrUtil.isNotBlank(cacheKey) && redisTemplate != null) {

        t = (T) redisTemplate.opsForHash().get(cacheKey, valueKey);

    }

    return t;

}
