如何为facebook画布应用程序配置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 

但是作为我的应用程序将在Facebook的帆布我想跳过登录到应用阶段（因为它是无意义的运行为用户显式登录到已被上运行我的应用程序Facebook）的流量将会是这样的;

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 

真的很感谢样品。

我刚刚注意到在gitspring-social-samples上有一个样本专门用于画布使用。
