The starter only gives you a default authorization page. It's a nice start, but you probably won't want to actually use it because it's rather plain looking. Instead, you'd create your own authorization page with a form that POSTs to /connect/facebook. In that form, you provide a hidden field named "scope" that contains a comma-separated list of any of the permissions you'd like from Facebook.
First, you'll want to make sure that you do NOT set the spring.social.auto_connection_views property (or, if you do, set it to false). Then create a view (JSP, Thymeleaf, whatever) that matches "connect/facebookConnect". Within that, include the form that POSTs to /connect/facebook with a "scope" hidden field.
As an example, have a look at https://github.com/spring-projects/spring-social-samples/tree/master/spring-social-showcase-boot. That project uses Thymeleaf templates and you can find the facebookConnect.html template in src/main/resources/templates/connect/facebookConnect.html.
