What are the redis serialization methods?

Use the following serialization method for redis value:

1: JdkSerializationRedisSerializer: (Recommended learning: Redis Video tutorial)

2: GenericJackson2JsonRedisSerializer

3: StringRedisSerializer

4: GenericFastJsonRedisSerializer

Found only 4: GenericFastJsonRedisSerializer, the best to use, not Error reporting

The following is a brief introduction one by one

1: JdkSerializationRedisSerializer:

Serializing java objects encounters the following error reporting :

DefaultSerializer requires a Serializable payload but received an object of type [com.everestfortune.cf.bean.CaseInfoBean]

Switch to logDB

Reason: Beans serialized using JdkSerializationRedisSerializer must implement the Serializable interface

2: GenericJackson2JsonRedisSerializer

Obtaining data from redis encountered the following error:

2019-04-26 11:26:41.510 ERROR 11656 --- [nio-9076-exec-7] c.e.cf.controller.ApplyController

: redis failed to obtain data, mes=Could not read JSON: Cannot construct instance of `java.time.LocalDate`

(no Creators, like default construct, exist):
 cannot deserialize from Object value (no delegate- or property-based Creator)

Reason: LocalDate is a new class in java8, and the GenericJackson2JsonRedisSerializer serialization method cannot be recognized

3: StringRedisSerializer

cannot serialize beans, only characters. String type data, if the values ​​are all string types, can be serialized in this way

4: GenericFastJsonRedisSerializer:

No problems have been found so far, it is very easy to use
