How-to: Implement core services with JSON-backed store

[jgrandja]

We should provide a guide that demonstrates how to implement RegisteredClientRepository, OAuth2AuthorizationService and OAuth2AuthorizationConsentService using a JSON-backed store (e.g. Redis).

Is there an implementation for Redis now

I saw a Redis implementation here before, but now it's gone

[littlefisher666]

I'm waiting.

I guess this could be used with MongoDb aswell, looking forward!

I tried implementing a RedisOAuth2AuthorizationService: https://github.com/wapkch/spring-authorization-server-demo/blob/main/src/main/java/sample/redis/RedisOAuth2AuthorizationService.java

I implemented a RedisOAuth2AuthorizationService based on redis storage in a jpa-like way
GitHub：https://github.com/vains-Sofia/authorization-example/blob/master/authorization-server/src/main/java/com/example/service/impl/RedisOAuth2AuthorizationService.java
Gitee：https://gitee.com/vains-Sofia/authorization-example/blob/master/authorization-server/src/main/java/com/example/service/impl/RedisOAuth2AuthorizationService.java

In the future, I will try to use the same method to implement RegisteredClientRepository and OAuth2AuthorizationConsentService.

[vains-Sofia]

Sorry, didn't have time to implement it until now, have now added Redis based RegisteredClientRepository and OAuth2AuthorizationConsentService implementation using the same way (similar to Jpa)

RedisRegisteredClientRepository:

RedisOAuth2AuthorizationConsentService:

How-to: Handle the expiration of the Secondary Index

There is currently no good solution. One stupid way is to manually set the expiration time of the Secondary Index.

Problem solved;
Add annotation on SpringBean: @EnableRedisRepositories(enableKeyspaceEvents = RedisKeyValueAdapter.EnableKeyspaceEvents.ON_STARTUP), as shown below: Gitee，Github
