我在facebook登录集成方面遇到了一些问题。 这是我的社交配置：
@Configuration
@EnableSocial
public class SocialConfig implements SocialConfigurer {
private final Logger log = LoggerFactory.getLogger(SocialConfig.class);
@Inject
Environment environment;
@Inject
ConnectionRepository customSocialConnectionRepository;
@Inject
SocialUserConnectionRepository socialUserConnectionRepository;
@Bean
public ConnectController connectController(ConnectionFactoryLocator connectionFactoryLocator) {
ConnectController controller = new ConnectController(connectionFactoryLocator, customSocialConnectionRepository);
controller.addInterceptor(new FacebookCustomConnectInterceptor());
return controller;
}
@Override
public void addConnectionFactories(ConnectionFactoryConfigurer connectionFactoryConfigurer, Environment environment) {
// Facebook configuration
String facebookClientId = environment.getProperty("spring.social.facebook.clientId");
String facebookClientSecret = environment.getProperty("spring.social.facebook.clientSecret");
if (facebookClientId != null && facebookClientSecret != null) {
log.debug("Configuration FacebookConnectionFactory");
connectionFactoryConfigurer.addConnectionFactory(
new FacebookConnectionFactory(
facebookClientId,
facebookClientSecret
)
);
} else {
log.error("Cannot configure FacebookConnectionFactory id or secret null");
}
}
@Override
public UserIdSource getUserIdSource() {
return new AuthenticationNameUserIdSource();
}
@Override
public UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
return new CustomSocialUsersConnectionRepository(socialUserConnectionRepository, connectionFactoryLocator);
}
}
我有商店SocialUserConnection的域对象。
我覆盖了ConnectionRepository
public class CustomSocialConnectionRepository implements ConnectionRepository {
private String userId;
private SocialUserConnectionRepository socialUserConnectionRepository;
private ConnectionFactoryLocator connectionFactoryLocator;
public CustomSocialConnectionRepository(String userId, SocialUserConnectionRepository socialUserConnectionRepository, ConnectionFactoryLocator connectionFactoryLocator) {

List<Connection<?>> connections = socialUserConnectionsToConnections(socialUserConnections);
MultiValueMap<String, Connection<?>> connectionsByProviderId = new LinkedMultiValueMap<>();
Set<String> registeredProviderIds = connectionFactoryLocator.registeredProviderIds();
for (String registeredProviderId : registeredProviderIds) {
connectionsByProviderId.put(registeredProviderId, Collections.emptyList());
}
for (Connection<?> connection : connections) {
String providerId = connection.getKey().getProviderId();
if (connectionsByProviderId.get(providerId).size() == 0) {
connectionsByProviderId.put(providerId, new LinkedList<>());
}
connectionsByProviderId.add(providerId, connection);
}
return connectionsByProviderId;
}
@Override
public List<Connection<?>> findConnections(String providerId) {
List<SocialUserConnection> socialUserConnections = socialUserConnectionRepository.findAllByUserIdAndProviderIdOrderByRankAsc(userId, providerId);
return socialUserConnectionsToConnections(socialUserConnections);
}
@Override

List<String> providerUserIds = entry.getValue();
List<Connection<?>> connections = providerUserIdsToConnections(providerId, providerUserIds);
connections.forEach(connection -> connectionsForUsers.add(providerId, connection));
}
return connectionsForUsers;

和UsersConnectionRepository（http://pastebin.com/7UzsndJq）
我使用ConnectController处理facebook连接，注册并登录用户进入应用程序。
public class FacebookCustomConnectInterceptor implements ConnectInterceptor<Facebook> {
private final Logger log = LoggerFactory.getLogger(FacebookCustomConnectInterceptor.class);
@Inject
SocialService socialService;
@Inject
CustomSocialUsersConnectionRepository customSocialUsersConnectionRepository;
@Inject
SocialUserConnectionRepository socialUserConnectionRepository;
@Override
public void preConnect(ConnectionFactory<Facebook> connectionFactory, MultiValueMap<String, String> valueMap, WebRequest request) {
// events before connection
}
@Override
public void postConnect(Connection<Facebook> connection, WebRequest request) {
UserProfile userProfile = connection.fetchUserProfile();
socialService.loginOrCreateFacebookUser(userProfile);
}
}
public void loginOrCreateFacebookUser(UserProfile userProfile) {
SocialUserConnection socialUserConnection = socialUserConnectionRepository.findOneByEmailAndProviderId(userProfile.getEmail(), "facebook");
Optional<User> foundUser = userRepository.findByUsername(socialUserConnection.getEmail());
User user = new User();
if(!foundUser.isPresent()) {
user.setUsername(socialUserConnection.getEmail());
user.setEmail(socialUserConnection.getEmail());
user.setPassword(RandomUtil.generatePassword());
user.setActivated(true);
Authority authority = authorityRepository.findOne("ROLE_USER");
Set<Authority> authorities = new HashSet<>();
authorities.add(authority);
user.setAuthorities(authorities);
user = userRepository.save(user);
}
else {
user = foundUser.get();
}
String lowercaseLogin = user.getUsername().toLowerCase();
List<GrantedAuthority> grantedAuthorities = user.getAuthorities().stream()
.map(authority -> new SimpleGrantedAuthority(authority.getName()))
.collect(Collectors.toList());
UserDetails userDetails = new org.springframework.security.core.userdetails.User(lowercaseLogin,
user.getPassword(),
grantedAuthorities);
Authentication authentication = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
//SecurityContextHolder.clearContext();
SecurityContextHolder.getContext().setAuthentication(authentication);
}
问题是当我尝试在postConnect中运行某些功能时。当我尝试这样做时，我得到错误： WARN 3232 --- [nio-8080-exec-3] o.s.s.connect.web.ConnectController：处理OAuth2回调时出现异常（null）。重定向到Facebook连接状态页面。

我使用Spring Boot 1.3.5

Create a your own User Class with the fields you required.
(Fields that are able to use:
{ "id", "about", "age_range", "birthday", "context", "cover", "currency", "devices", "education", "email", "favorite_athletes", "favorite_teams", "first_name", "gender", "hometown", "inspirational_people", "installed", "install_type", "is_verified", "languages", "last_name", "link", "locale", "location", "meeting_for", "middle_name", "name", "name_format", "political", "quotes", "payment_pricepoints", "relationship_status", "religion", "security_settings", "significant_other", "sports", "test_group", "timezone", "third_party_id", "updated_time", "verified", "video_upload_limits", "viewer_can_send_gift", "website", "work"})
Replace the code similar to follow:
String [] fields = { "id", "email", "first_name", "last_name" }; //Depends on which field you want.
User userProfile = facebook.fetchObject("me", User.class, fields);
