Spring Session Token

Question

Explored spring session and redis it looks really good.

Trying to solve one question for a long time , how to retrieve list of session token from redis db based on the spring session token value in the hash .

I know its not a relational database and there is no straightforward way to achieve but is that a way to figure this out which is really important for us to solve problems

I read in blogs we need to keep a set to track , are there any ways to acheive this when using spring session. i am not even sure how to do this

Any help is highly appreciated .

Thank you

Useful Commands:

1. redis-cli : To enter into redis console Example:

   root@root>redis-cli

2. keys * :Shows all keys stored in redis DB
   Example:

   127.0.0.1:6379>keys *

   “spring:session:expirations:1440354840000“

   “spring:session:sessions:3b606f6d-3d30-4afb-bea6-ef3a4adcf56b“

3. monitor : To monitor the redis DB

4. hgetall SESSION_ID :To check all the keys stored inside a session
