Is it normal to create a new Keycloak instance for each request? If I were to define a spring bean that returns a Keycloak instance or a RealmResource instance just to access user details, what bean scope should I use?

[jean-baptistedioli]

Hello Thanks for the tutorial

Can we also in this way add a ROLE to the user ?
if yes, can the authenticated user can and a specific ROLE to is own profile ?

[yasiruwickramanayake]

Hi sir, can we use keycloak for permission based authorization with spring boot. That means can we use permissions instead of roles with @preauthorize annotation. If you don't mind, could you please explain this?

[aliouthiema]

HI @czetsuyatech
I successfully integrated keycloack with spring largely thanks to your tutorial. so thank you very much.
I have a problem on the other hand.
I added an add user feature but I have a problem. indeed if I leave ** super.configure (http); ** I have a spring error ** Forbidden *** and if I remove it I have a keycloack error **

"class java.lang.String cannot be cast to class (java.lang.String is in module java.base of loader 'bootstrap'; is in unnamed module of loader 'app')"

ANy idea how to solve this ?

[tommasogalati]

Hi czetsuyatech. Your video was very interesting. I saw that you implemented separately frontend and api-service. Why? Does it's a best practice or your simply choice?

[siriusmarz]

Hey can you show in a tutorial how do spring keyclaok and angular in prod mode?
