我有一个可运行的spring mvc webapp,它是基于xml的,因此我必须使用相同的过程,而不是“ pure java configs”。
我正在尝试将Facebook登录集成到我的应用中,并且我尝试按照许多教程进行操作,但无法使其正常运行。
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:

家用控制器:
@Controller
公共类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
由以下原因引起:org.springframework.beans.factory.NoSuchBeanDefinitionException:未定义名为“ scopedTarget.connectionFactoryLocator”的bean
如果我删除了facebook:config标签,由于没有这样的bean,它会给我以下错误:
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
有什么建议么?
最佳答案
您无需将spring的facebook接口添加为xml中的类。而是使用您的Facebook客户端ID和使用xml或Java代码的密钥创建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")));
}
...
}
要么
使用Spring Social Facebook的XML配置名称空间:
<facebook:config app-id="${facebook.clientId}"
app-secret="${facebook.clientSecret}"
app-namespace="socialshowcase" />
