我正在尝试使用 Spring Social Facebook 来阅读我的应用程序（目前是一个简单的 Java 类测试）

但我遇到了一些问题。我创建了一个非常简单的项目（面向 maven），我正在使用 Spring social 1.1.0

我创建了以下 Java 类：

import it.eng.comi.spring.service.CoMiSocialNetworkingSvc;
import java.util.List;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.impl.client.HttpClients;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.core.env.Environment;
import org.springframework.http.client.ClientHttpRequestFactory;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.social.connect.support.ConnectionFactoryRegistry;
import org.springframework.social.facebook.api.Facebook;
import org.springframework.social.facebook.api.PagedList;
import org.springframework.social.facebook.api.Post;
import org.springframework.social.facebook.api.impl.FacebookTemplate;
import org.springframework.social.facebook.connect.FacebookConnectionFactory;
import org.springframework.social.oauth2.AccessGrant;
import org.springframework.social.oauth2.OAuth2Operations;
import org.springframework.social.twitter.api.Tweet;
import org.springframework.social.twitter.api.Twitter;
import org.springframework.social.twitter.api.impl.TwitterTemplate;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;

@Service
public class CoMiSocialNetworkSvcImpl implements CoMiSocialNetworkingSvc
{
    private static final Log logger = LogFactory.getLog(CoMiSocialNetworkSvcImpl.class.getName());
    @Value("${facebook.appId}")
    private String facebookAppId;
    @Value("${facebook.appSecret}")
    private String facebookAppSecret;
    @Value("${facebook.appNamespace}")
    private String facebookAppNamespace;
    @Autowired
    private ConnectionFactoryRegistry cfr;

    @Override
    public PagedList<Post> getPosts() throws Exception
    {

        try
        {

            FacebookConnectionFactory fcc = (FacebookConnectionFactory)cfr.getConnectionFactory("facebook");
            OAuth2Operations oauthOper = fcc.getOAuthOperations();
            String scope = "publish_stream,offline_access,read_stream,user_about_me,manage_pages";
            AccessGrant ag = oauthOper.authenticateClient(scope);
            String accessToken = ag.getAccessToken();
            logger.info("Access Token: "+accessToken);
            Facebook facebook = new FacebookTemplate(accessToken);
            PagedList<Post> result = facebook.feedOperations().getHomeFeed();
            result.addAll(facebook.feedOperations().getFeed());
            return result;
        }
        catch (Exception e)
        {
            String messagge = "Errore nel recupero feed: "+e.getMessage();
            logger.fatal(messagge, e);
            throw e;
        }
    }
}

我创建了这个简单的 JUnit 测试：

import java.util.List;
import it.eng.comi.spring.service.CoMiSocialNetworkingSvc;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.social.facebook.api.PagedList;
import org.springframework.social.facebook.api.Post;
import org.springframework.social.twitter.api.Tweet;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

@ContextConfiguration(value={
        "classpath:application-context-social.xml"
})

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class ComiSocialTests
{
    private static final Log logger = LogFactory.getLog(ComiSocialTests.class.getName());
    @Autowired
    private CoMiSocialNetworkingSvc social;
    @Test
    public void testFeeds()
    {
        try
        {
            PagedList<Post> feeds = social.getPosts();
            for (Post post : feeds)
            {
                logger.info("Caption "+post.getCaption()+" like counts "+post.getLikeCount()+" comments count: "+post.getCommentCount()+" descrizione "+post.getDescription());
            }
        }
        catch (Exception e)
        {
            logger.error(e.getMessage(), e);
        }
    }   
}

这是我的应用程序上下文 XML：

                </bean>
            </list>
        </property>
    </bean>
</beans>

当我尝试使用显示的实现（显示类的方法 getPosts()）与 FB 联系时，我收到此错误：

11:35:39,501 INFO  [CoMiSocialNetworkSvcImpl] Access Token: 868557579830099|4JH01Jwud-Ot0UTd_FoF_439r50

谁能建议我如何解决这个问题？我被困在这几天了，我无法解决它

谢谢安吉洛
