In my spring boot app, I want to keep the number of users who subscribe to each websocket channel.
I'd like to do this using a concurrent hashmap, but I don't know where I should keep this data structure, so all users share it. From my understanding, putting it in a component doesn't lead to being "shared" between requests.
I have to mention that I never touched sessions in my app, as authentication is based on JWT.

Create a Service/Bean which holds data in ehCache, good example here
I would not use a Map.
Based on Arian Hosseinzadeh below which I think is correct. Just create a normal @Service Bean, it will be a singleton by default.
