# Jackson 3 serializers: JacksonJsonRedisSerializer and GenericJacksonJsonRedisSerializer
|
|
|
|
|
|
--- JacksonJsonRedisSerializer<User>: one type, plain JSON ---
|
|
value serializer: org.springframework.data.redis.serializer.JacksonJsonRedisSerializer
|
|
userTemplate.opsForValue().set("user:1", new User(1, "Ankur"))
|
|
$ redis-cli -p 6390 KEYS '*'
|
|
user:1
|
|
$ redis-cli -p 6390 GET user:1
|
|
{"id":1,"name":"Ankur"}
|
|
read back: User[id=1, name=Ankur] (User)
|
|
|
|
--- GenericJacksonJsonRedisSerializer with an allow-list: any type, plus @class ---
|
|
value serializer: org.springframework.data.redis.serializer.GenericJacksonJsonRedisSerializer
|
|
jsonTemplate.opsForValue().set("user:2", new User(2, "Ankur"))
|
|
$ redis-cli -p 6390 GET user:2
|
|
{"@class":"com.ankurm.redis.model.User","id":2,"name":"Ankur"}
|
|
read back: User[id=2, name=Ankur] (User)
|
|
|
|
--- GenericJacksonJsonRedisSerializer with no typing configured ---
|
|
plain.opsForValue().set("user:3", new User(3, "Ankur"))
|
|
$ redis-cli -p 6390 GET user:3
|
|
{"id":3,"name":"Ankur"}
|
|
read back: {id=3, name=Ankur} (LinkedHashMap)
|
|
|
|
--- Two different shapes of the same JSON ---
|
|
$ redis-cli -p 6390 GET user:1
|
|
{"id":1,"name":"Ankur"}
|
|
$ redis-cli -p 6390 GET user:2
|
|
{"@class":"com.ankurm.redis.model.User","id":2,"name":"Ankur"}
