Role with Spring security

Help

Hi, All.

I wanted to add “role” claim to access token but it’s not possible.
I can use custom namespace with the role claim.
So…how can I configure “hasRole” method in Spring Security if the token value is ‘http://example.com/roles’=['admin’]?

        http.authorizeRequests()
                .mvcMatchers("/public").permitAll()
                .mvcMatchers("/private").authenticated()
                .mvcMatchers("/private-scoped").hasAuthority("SCOPE_read:messages")
                .mvcMatchers("/private-role").hasRole("admin") //how can?
                .and()
                .oauth2ResourceServer().jwt();

Thanks!
