Question

我有一个工作的spring mvc webapp，它是基于xml的，所以我必须使用相同的程序，而不是“纯java配置”。

我正在尝试将facebook登录集成到我的应用程序中，我试图遵循许多教程，但却无法让它们发挥作用。

以下是我的尝试之一：（https://spring.io/guides/gs/accessing-facebook/）

修改

我的XML现在是这样的：

        </bean>

        <bean id="connectionRepository" factory-method="createConnectionRepository" 
              factory-bean="usersConnectionRepository" scope="request">

            <aop:scoped-proxy proxy-target-class="false" />
        </bean>

        <bean class="org.springframework.social.connect.web.ConnectController">
            <!-- relies on by-type autowiring for the constructor-args -->

    <facebook:config app-id="962223610477458" app-secret="b7dfec28b08ac4e8c2a09cbac4662c15" app-namespace="setelog_selectandwin" />

</beans>

HomeController中：

@Controller 公共课HomeController {

private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

private Facebook facebook;
private ConnectionRepository connectionRepository;

@Inject
public HomeController(Facebook facebook, ConnectionRepository connectionRepository) {
    this.facebook = facebook;
    this.connectionRepository = connectionRepository;
}

/**
 * Simply selects the home view to render by returning its name.
 */
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
     if (connectionRepository.findPrimaryConnection(Facebook.class) == null) {
            return "redirect:/connect/facebook";
        }

        model.addAttribute("facebookProfile", facebook.userOperations().getUserProfile());
        PagedList<Post> feed = facebook.feedOperations().getFeed();
        model.addAttribute("feed", feed);
        return "facebook/hello";
}

}

现在错误是引起：org.springframework.beans.factory.NoSuchBeanDefinitionException：没有定义名为'scopedTarget.connectionFactoryLocator'的bean

如果我删除了facebook：config标签，它会给我以下错误，因为没有这样的bean：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.springframework.social.facebook.api.Facebook] found for dependency: expected at least 1 bean which

有什么建议吗？

Answer 1

您无需在xml中将spring的facebook界面添加为类。而是使用你的facebook客户端id和秘密使用xml或java代码创建FacebookConnectionFactory。

@Configuration
public class SocialConfig implements SocialConfigurer {

    @Override
    public void addConnectionFactories(ConnectionFactoryConfigurer cfConfig, Environment env) {
        cfConfig.addConnectionFactory(new FacebookConnectionFactory(
            env.getProperty("facebook.clientId"),
            env.getProperty("facebook.clientSecret")));
    }

    ...
}

或

使用Spring Social Facebook的XML配置命名空间：

<facebook:config app-id="${facebook.clientId}"
                 app-secret="${facebook.clientSecret}"
                 app-namespace="socialshowcase" />

参考：Spring Social Facebook Reference

Answer 2

摘自春季社交快速启动示例。可能你不能自己注射它，而是你必须使用类似工厂的方法：

@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)   
public Facebook facebook() {
    return connectionRepository().getPrimaryConnection(Facebook.class).getApi();
}

它需要其他依赖项，没有必要在这里复制粘贴它们。看看：https://github.com/spring-projects/spring-social-samples/blob/master/spring-social-quickstart/src/main/java/org/springframework/social/quickstart/config/SocialConfig.java
