我已经实现了Spring Social，并且已经成功实现了ProviderSignInController来验证与Facebook的连接。
作为其中的一部分，我需要实现SignInAdapter接口。我理解这个接口用于与提供者成功认证的最后步骤，特别是我重写了signIn方法，以便在与提供者成功认证后以编程方式将客户端记录到我的应用程序中。
我的问题是，当我实现SignInAdapter时，它不会在成功登录时触发signIn（）方法。
代码几乎直接来自Spring showcase examples：
public class SimpleSignInAdapter implements SignInAdapter {
private static final Logger logger = LoggerFactory.getLogger(SimpleSignInAdapter.class);
private final RequestCache requestCache;
@Inject
public SimpleSignInAdapter(RequestCache requestCache) {
this.requestCache = requestCache;
logger.debug("Constructing " + SimpleSignInAdapter.class.getCanonicalName());
}
@Override
public String signIn(String localUserId, Connection<?> connection, NativeWebRequest request) {
/* A social profile has been found. Now we need to log that user into the
* application programatically.
*
* No other credentials are necessary here because by the time this method
* is called the user will have signed into the provider and their connection
* with that provider has been used to prove the user's identity.
*/
logger.debug("A social profile has been found. Now we need to log that user into the app.");
SignInUtils.signin(localUserId);
return null;
}
private String extractOriginalUrl(NativeWebRequest request) {
HttpServletRequest nativeReq = request.getNativeRequest(HttpServletRequest.class);
HttpServletResponse nativeRes = request.getNativeResponse(HttpServletResponse.class);
SavedRequest saved = requestCache.getRequest(nativeReq, nativeRes);
if (saved == null) {
return null;
}
requestCache.removeRequest(nativeReq, nativeRes);
removeAutheticationAttributes(nativeReq.getSession(false));
return saved.getRedirectUrl();
}
private void removeAutheticationAttributes(HttpSession session) {
if (session == null) {
return;
}
session.removeAttribute(WebAttributes.AUTHENTICATION_EXCEPTION);
}
}
有趣的是，SimpleSignInAdapter是构造的，因为我可以通过该步骤调试并在日志中查看我的调试输出，因此看起来Bean正在实例化而不是触发signIn方法。
这是我的Spring配置：
@Configuration
@ComponentScan(basePackages = "com.mycompany.webclient")
@PropertySource("classpath:app.properties")
@ImportResource("/WEB-INF/spring/appServlet/security-app-context.xml")
public class MainConfig {
@Bean
public PropertySourcesPlaceholderConfigurer propertyPlaceHolderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
我的Spring Social配置是：
@Configuration
@EnableSocial
public class SocialConfig implements SocialConfigurer {
private SocialUserDAO socialUserDao;
//
// SocialConfigurer implementation methods
//
@Override
public void addConnectionFactories(ConnectionFactoryConfigurer cfConfig, Environment env) {
cfConfig.addConnectionFactory(new FacebookConnectionFactory("XXXXXXXXX", "XXXXXXXXX"));
cfConfig.addConnectionFactory(new TwitterConnectionFactory("XXXXXXXXX", "XXXXXXXXX"));
}
@Override
public UserIdSource getUserIdSource() {
return new UserIdSource() {
@Override
public String getUserId() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication == null) {
throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
}
return authentication.getName();
}
};
}
@Override
public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
return new HibernateUsersConnectionRepository(socialUserDao, connectionFactoryLocator, Encryptors.noOpText());
}
//
// API Binding Beans
//
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public Facebook facebook(ConnectionRepository repository) {
Connection<Facebook> connection = repository.findPrimaryConnection(Facebook.class);
return connection != null ? connection.getApi() : null;
}
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public Twitter twitter(ConnectionRepository repository) {
Connection<Twitter> connection = repository.findPrimaryConnection(Twitter.class);
return connection != null ? connection.getApi() : null;
}
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public LinkedIn linkedin(ConnectionRepository repository) {
Connection<LinkedIn> connection = repository.findPrimaryConnection(LinkedIn.class);
return connection != null ? connection.getApi() : null;
}
//
// Web Controller and Filter Beans
//
@Bean
public ConnectController connectController(ConnectionFactoryLocator connectionFactoryLocator, ConnectionRepository connectionRepository) {
ConnectController connectController = new ConnectController(connectionFactoryLocator, connectionRepository);
connectController.addInterceptor(new PostToWallAfterConnectInterceptor());
connectController.addInterceptor(new TweetAfterConnectInterceptor());
return connectController;
}
@Bean
public ProviderSignInController providerSignInController(ConnectionFactoryLocator connectionFactoryLocator, UsersConnectionRepository usersConnectionRepository) {
return new ProviderSignInController(connectionFactoryLocator, usersConnectionRepository, new SimpleSignInAdapter(new HttpSessionRequestCache()));
}
@Bean
public DisconnectController disconnectController(UsersConnectionRepository usersConnectionRepository, Environment env) {
return new DisconnectController(usersConnectionRepository, env.getProperty("facebook.clientSecret"));
}
@Bean
public ReconnectFilter apiExceptionHandler(UsersConnectionRepository usersConnectionRepository, UserIdSource userIdSource) {
return new ReconnectFilter(usersConnectionRepository, userIdSource);
}
}
有没有办法让我确认为什么signIn（）没有被解雇，或者即使它正在被注册。
