Question

我尝试配置facebook集成。但是我没有正确地回忆accessToken。我收到了null。记录器向我显示变量AccesToken和UserID，它为null。

所以这是我的配置。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="customArgumentResolver" ref="facebookWebArgResolver" />
    </bean>
    <bean id="facebookWebArgResolver"
        class="org.springframework.social.facebook.FacebookWebArgumentResolver">
        <constructor-arg name="apiKey" value="${facebook.appId}"/>
    </bean>
</beans>

这是我的带有FacebookProvider和jsp页面的回调控制器。

@Controller
public class SocialTutorial {
    private static final Logger LOG = Logger.getLogger(SocialTutorial.class);
    @Autowired
    FacebookProvider facebookProvider;

    @RequestMapping(value = "/connect/facebook", method = RequestMethod.POST)
    public String connectAccountToFacebook(@FacebookAccessToken String accessToken, @FacebookUserId String facebookUserId) {
        LOG.error("HERE facebook authnticate:" + accessToken + " And user id:" + facebookUserId);
        return "redirect:/pages/social.jsp";
    }

}

@Repository("facebookProvider")
public class FacebookProvider {
    @Value("${facebook.appId}")
    private String apiKey;// = "240362226072898";
    @Value("${facebook.appSecret}")
    private String appSecret;// = "     ";

    public String getApiKey() {
        return apiKey;
    }

    public void setApiKey(String apiKey) {
        this.apiKey = apiKey;
    }

    public String getAppSecret() {
        return appSecret;
    }

    public void setAppSecret(String appSecret) {
        this.appSecret = appSecret;
    }


    public FacebookTemplate createTemplate(String accesToken) {
        return new FacebookTemplate(accesToken);
    }
}

试试这个。它应该适合你：

FacebookConnectionFactory connectionFactory = 
new FacebookConnectionFactory("clientId", "clientSecret");
OAuth2Operations oauthOperations = connectionFactory.getOAuthOperations();
OAuth2Parameters params = new OAuth2Parameters();
params.setRedirectUri("https://my-callback-url");
String authorizeUrl = oauthOperations.buildAuthorizeUrl(GrantType.AUTHORIZATION_CODE, params);
response.sendRedirect(authorizeUrl);

// upon receiving the callback from the provider:
AccessGrant accessGrant = oauthOperations.exchangeForAccess(authorizationCode,      "https://my-callback-url", null);
Connection<Facebook> connection = connectionFactory.createConnection(accessGrant);
