import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.cache.RedisCacheWriter;
import org.springframework.data.redis.connection.RedisConnectionFactory;


import javax.annotation.Resource;
import java.time.Duration;

@Configuration
@EnableCaching
public class CachingConfig {

    @Bean
    public RedisCacheManager redisCacheManager(RedisConnectionFactory connectionFactory){


        RedisCacheWriter redisCacheWriter = RedisCacheWriter
                .lockingRedisCacheWriter(connectionFactory);
        RedisCacheConfiguration cacheConfiguration = RedisCacheConfiguration.defaultCacheConfig();
        cacheConfiguration = cacheConfiguration.entryTtl(Duration.ofSeconds(30));

        RedisCacheManager redisCacheManager = new RedisCacheManager(redisCacheWriter,
                cacheConfiguration);
        return redisCacheManager;
