Facebook4j身份验证问题

Question

我正在尝试创建一个与facebook连接的java应用程序。我正在使用facebok4j来实现这一点，我在fb devolopers中创建了一个应用程序并获得了它的密钥和ID。但是当我传递它以获得一个访问令牌返回异常错误。请帮助我

java代码

import java.io.BufferedWriter; 
import java.io.File; 
import java.io.FileWriter; 
import java.io.IOException; 

import net.sf.json.JSONArray; 
import net.sf.json.JSONObject; 
import facebook4j.Facebook; 
import facebook4j.FacebookException; 
import facebook4j.FacebookFactory; 
import facebook4j.Post; 
import facebook4j.ResponseList;
import facebook4j.auth.AccessToken;
import facebook4j.auth.OAuthAuthorization;
import facebook4j.auth.OAuthSupport;
import facebook4j.conf.Configuration; 
import facebook4j.conf.ConfigurationBuilder; 
public class Fbsample {
public static  Configuration createConfiguration() 
{
    ConfigurationBuilder confBuilder = new ConfigurationBuilder();

    confBuilder.setDebugEnabled(true);
    confBuilder.setOAuthAppId("*****");
    confBuilder.setOAuthAppSecret("*****");
    confBuilder.setUseSSL(true);
    confBuilder.setJSONStoreEnabled(true);
    Configuration configuration = confBuilder.build();
    return configuration;
}
public static void main(String[] argv) throws FacebookException {
    Configuration configuration =  createConfiguration();
    FacebookFactory facebookFactory = new FacebookFactory(configuration );
    Facebook facebookClient = facebookFactory.getInstance();
    AccessToken accessToken = null;
    try{
        OAuthSupport oAuthSupport = new OAuthAuthorization(configuration );
        accessToken = oAuthSupport.getOAuthAppAccessToken();

    }catch (FacebookException e) {
        System.err.println("Error while creating access token " + e.getLocalizedMessage());
    }
    facebookClient.setOAuthAccessToken(accessToken);
//results in an error says {An active access token must be used to query information about the current user}
}

}
