[keycloak-user] Keycloak fine grained permissions with Spring Boot / Spring Security

[David Marsh]

I would like to use permissions or scopes or similar to allow fine grained access to REST resource.

Ideally I would like to do something like:


@PreAuthorize("hasPermission('Brands', 'brands:write')")

ResponseEntity<Brand> getBrand(@PathVariable("brandCode") String brandCode);

where 'Brands' is a keycloak client authorization resource with scopes 'brands:write, brands:read'.

The only annotation that seems to work is @Secured with a role, I do not with to do RBAC.

@Secured({"ROLE_STAFF"})

I have looked at the PolicyEnforcer, it is unclear to me exactly how it is supposed to be used.

I can write code of the form:


KeycloakSecurityContext keycloakSecurityContext = (KeycloakSecurityContext) request.getAttribute(KeycloakSecurityContext.class.getName());
AuthorizationContext authzContext = keycloakSecurityContext.getAuthorizationContext();
if (authzContext.hasScopePermission("brands:write")) {

     // This works....
}

How can I tie the AuthorizationContext from PolicyEnforcing to the standard Spring security annotations ?

thanks
