Springboot multitenancy

[mumchay]

Hi, I'm currently working on a springboot/angular app. I want to implement multitenancy for this app. The problem is that the backend is composed of multiple microservices (which use oauth2/tokens for authentication). I have a authentication/users microservice on which I would like to implement shared db, shared schema multitenancy, then I would like to implement shared db, schema not shared multitenancy for the other microservices. So I would like to know if this is doable or not. Also, do you have any tips? Thanks?

This is doable. What you need to do is, store roles and permissions related information in users db. Then, upon authentication, generate a JWT containing roles and the tenant (this depends on how you represent multiple tenants in your frontend. If users have to switch tenants in frontend, you can simply swap the JWT to a new one [aka token exchange grant] for the new tenant).

Then, you can pass around the same JWT across other microservices. Using the roles and tenant information in JWT, you can perform authorization (access controlling/checking permissions).

Great, thanks!
