How to do it…

Here are the steps to retrieve the profile of a Facebook user:

   @RequestMapping("/fb")
   public String fb(HttpServletRequest request, Model model) {

2. In the if(facebook.isAuthorized()) block, use the Facebook object to retrieve the user's profile:

   FacebookProfile profile = facebook.userOperations().getUserProfile(); 

3. Pass the user profile to the JSP view:

   model.addAttribute("profile", profile);

   id: ${profile.id}<br />
   username: ${profile.username}<br />
