How exactly are the roles checked in this scenario? Suppose you have and endpoint that has in configuration a restriction: hasRole("ADMIN"). How would the authorization filter work then?

  1. JwtAuthenticationFilter saves user data and roles into JWT when the user logs in.
  2. JwtAuthorizationFilter parses the JWT during every HTTP request and load user data and roles from JWT into Spring's security context.
  3. hasRole("ADMIN") reads roles from security context and allows request only if there is "ROLE_ADMIN".

In my example, roles and user are defined in SecurityConfiguration (in-memory user).
