我花了幾個小時試圖讓Twitter集成與Spring Social一起使用XML配置方法。我可以在網上找到的所有實例（和計算器）始終使用@Config方法如圖所示samples如何通過XML配置Spring Social
無論出於何種原因bean定義來獲得一個實例到Twitter API拋出一個AOP例外：
Caused by: java.lang.IllegalStateException: Cannot create scoped proxy for bean 'scopedTarget.twitter': Target type could not be determined at the time of proxy creation.
下面是完整的配置文件，我有：

令我百思不解的是，connectionRepository實例工作完全正常（我註釋掉嘰嘰喳喳豆和測試代碼！）？！？它使用相同的功能：請求範圍和接口AOP代理和工作，但twitter bean實例化失敗？！？
彈簧社會配置代碼如下（我看不出任何差異，可以嗎？）：
@Configuration
public class SocialConfig {
@Inject
private Environment environment;
@Inject
private DataSource dataSource;
@Bean
@Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES)
public ConnectionFactoryLocator connectionFactoryLocator() {
ConnectionFactoryRegistry registry = new ConnectionFactoryRegistry();
registry.addConnectionFactory(new TwitterConnectionFactory(environment.getProperty("twitter.consumerKey"),
environment.getProperty("twitter.consumerSecret")));
return registry;
}
@Bean
@Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES)
public UsersConnectionRepository usersConnectionRepository() {
return new JdbcUsersConnectionRepository(dataSource, connectionFactoryLocator(), Encryptors.noOpText());
}
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public ConnectionRepository connectionRepository() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication == null) {
throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
}
return usersConnectionRepository().createConnectionRepository(authentication.getName());
}
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public Twitter twitter() {
Connection<Twitter> twitter = connectionRepository().findPrimaryConnection(Twitter.class);
return twitter != null ? twitter.getApi() : new TwitterTemplate();
}
@Bean
public ConnectController connectController() {
ConnectController connectController = new ConnectController(connectionFactoryLocator(), connectionRepository());
connectController.addInterceptor(new PostToWallAfterConnectInterceptor());
connectController.addInterceptor(new TweetAfterConnectInterceptor());
return connectController;
}
@Bean
public ProviderSignInController providerSignInController(RequestCache requestCache) {
return new ProviderSignInController(connectionFactoryLocator(), usersConnectionRepository(), new SimpleSignInAdapter(requestCache));
}
}
任何幫助/指針將不勝感激！
那麼，正如我所說......官方文件不包括我的問題涉及到的缺失部分。 spring-social-showcase應用程序使用基於註解的@Config配置。你的例子不包括缺少的部分 - 「twitter」的bean定義 - 但是，儘管如此，謝謝！乾杯! –
