# Redis as the Spring cache with a Jackson 3 value serializer


--- The result that was not Serializable now caches ---
find(1) called twice, method body ran 1 time(s)
second call returned: User[id=1, name=Ankur]

--- What is in Redis ---
$ redis-cli -p 6390 KEYS '*' | sort
users::1
$ redis-cli -p 6390 GET users::1
{"@class":"com.ankurm.redis.model.User","id":1,"name":"Ankur"}
$ redis-cli -p 6390 --no-raw TTL users::1
(integer) 300
spring.cache.redis.time-to-live=10m is set, and the bean says 5 minutes
