@controller @requestmapping("/") public class homecontroller {    @value("#{facebookappid['app_key']}")   private static string app_key;   @value("#{facebookappsecret['secret']}")   private static string app_secret;    private facebookclient.accesstoken getfacebookusertoken(string code, string url) throws ioexception {    webrequestor web = new defaultwebrequestor();    webrequestor.response accesstokens = web.executeget("https://graph.facebook.com/oauth/access_token?client_id="+    app_key+url+"&client_secret="+app_secret+"&code=" + code);       return     defaultfacebookclient.accesstoken.fromquerystring(accesstokens.getbody());  }        @requestmapping(method= requestmethod.get)       public string hellofacebook(model model) {          string url = "https://www.facebook.com/dialog/oauth?"+app_key;         return "redirect"+url;     }    }

you can use obtainuseraccesstoken defaultfacebookclient facebookclient facebookclient = new defaultfacebookclient(version.version_2_2); facebookclient.obtainuseraccesstoken(appid, appsecret, redirecturi, verificationcode);
