@Configuration
public class RedisConfig extends CachingConfigurerSupport {
    @Bean
    public RedisTemplate<Object,Object> redisTemplate(RedisConnectionFactory connectionFactory){
        RedisTemplate<Object ,Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setConnectionFactory(connectionFactory);
        return redisTemplate;
