WebArgumentResolver

public class FacebookWebArgumentResolver
extends java.lang.Object
implements WebArgumentResolver

Web argument resolver that resolves arguments annotated with FacebookAccessToken or FacebookUserId.

After a user has authenticated with Facebook via the XFBML <fb:login-button> tag, their user ID and an access token are stored in a cookie whose name is "fbs_{application key}". This web argument resolver extracts that information from the cookie (if available) and supplies it to a controller handler method as String values.
