Как да създадете RedisCacheManager в spring-data 2.0.x

опитайте следния код, той работи за мен на spring-boot 2.1.0.RELEASE

@Bean
public RedisCacheManager redisCacheManager(LettuceConnectionFactory lettuceConnectionFactory) {
    RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
            .disableCachingNullValues()
            .entryTtl(Duration.ofHours(1))
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.json()));
    redisCacheConfiguration.usePrefix();

   return RedisCacheManager.RedisCacheManagerBuilder.fromConnectionFactory(lettuceConnectionFactory)
                    .cacheDefaults(redisCacheConfiguration).build();

}
