Я очень плохо знаком с Spring и Spring Security и надеюсь, что кто-нибудь может помочь мне решить следующую проблему.
Чего я хочу добиться - это извлечь имя пользователя и адрес электронной почты после успешной аутентификации этого пользователя провайдером OpenID (gmail), а затем проверить базу данных, чтобы загрузить пользовательскую модель для этого пользователя.
В моем файле spring-security.xml у меня есть

<bean id="userDetailsServiceOpenIDImpl" class="org.school.openid.service.UserDetailsServiceOpenIDImpl" />
</beans>
моя проблема в UserDetailsServiceOpenIDImpl.java is
public class UserDetailsServiceOpenIDImpl implements UserDetailsService {
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException, DataAccessException {
System.out.println(username);
//extract username and email address, HOW?
}
}
Оператор print печатает что-то вроде
<b>https://www.google.com/accounts/o8/id?id=AItOawlq2C3EdFAuqp-ski_xkgB8jsEKbe-mZE</b>
Мои вопросы
(1) Как я могу извлечь имя пользователя и адрес электронной почты из возвращенного URL-адреса (кроме того, я даже не уверен, правильно ли вернулись имя пользователя и адрес электронной почты)?
(2) При запуске отладки в Eclipse YouEatAuthenticationSuccessHandler, по-видимому, не вызывается, когда возвращается URL (https://www.google.com/accounts/o8/id?id=AItOawlq2C3EdFAuqp-ski_xkgB8jsEKbe-mZE).
Спасибо.
Edit:
спасибо за ссылку http://static.springsource.org/spring-security/site/docs/3.0.x/reference/ns-config.html#ns-openid.
В нем говорится, что «Значения атрибутов возвращаются как часть процесса аутентификации и могут быть впоследствии доступны с помощью следующего кода: ...»
Я добавил
OpenIDAuthenticationToken token = (OpenIDAuthenticationToken)SecurityContextHolder.getContext().getAuthentication();
List attributes = token.getAttributes();
в метод loadUserByUsername. Но объект "токен" является нулевым.

На следующей странице https://fisheye.springsource.org/browse/spring-security/samples/openid/src/main/webapp/WEB-INF/applicationContext-security.xml?hb=true, я могу добавить имя и адрес электронной почты для пользователя.
