如何爲facebook畫布應用程序配置spring-social-facebook

Question

查看Keith Donald's和Roger Hughes's春季教程，流程如下;

IF user is signed in to to application THEN 
    IF user is signed in to Facebook 
     read Facebook data, 
     display Facebook data 
    ELSE (facebook handles) 
     ask user to loging to Facebook 
     goto if user is signed in to Facebook step 
    ENDIF 
ELSE 
    ask user to sign in 
    create user object with an id 
    when user has signed in, go back to the beginning 
END IF 

但是作爲我的應用程序將在Facebook的帆布我想跳過登錄到應用階段（因爲它是無意義的運行爲用戶顯式登錄到已被上運行我的應用程序Facebook）的流量將會是這樣的;

create a user (session scope) 
    IF user is signed in to Facebook 
     update user object with facebook id 
     read Facebook data, 
     display Facebook data 
    ELSE (facebook handles) 
     ask user to loging to Facebook 
     goto if user is signed in to Facebook step 
    ENDIF 

真的很感謝樣品。

我剛剛注意到在gitspring-social-samples上有一個樣本專門用於畫布使用。
