java - 将 Spring Socials (Facebook) 与基于 XML 的 Spring MVC 集成

Question

我有一个正在运行的 spring mvc webapp，它是基于 xml 的，所以我必须使用相同的过程，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，并且我尝试遵循许多教程，但无法使它们正常工作。

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

编辑:

我的 XML 现在是这样的:

<?xml version="1.0" encoding="UTF-8"?>

        <bean id="connectionRepository" factory-method="createConnectionRepository"

        </bean>

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

        <bean class="org.springframework.social.connect.web.ConnectController">

            <property name="applicationUrl" value="${application.url}" />
        </bean>



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

</beans>

家庭 Controller :

@ Controller 公共(public)类 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";
}

}

现在错误是导致:org.springframework.beans.factory.NoSuchBeanDefinitionException:没有定义名为“scopedTarget.connectionFactoryLocator”的bean

如果我删除 facebook:config 标签，则会出现以下错误，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

你不需要在你的xml中添加spring的facebook接口(interface)作为类。相反，使用 xml 或 java 代码使用您的 facebook 客户端 ID 和 key 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" />
