无法在春季社交网站中使用其他Facebook（或Google）用户登录

Question

我正在实施spring-social-facebook和spring-social-google。到目前为止，我已设法登录并注销用户，将其与我的数据库等一起保存。所以一切都按预期工作。但是当我登录然后尝试使用其他Facebook（或Google）用户登录时，我的Facebook（或Google）对象会返回首次登录的用户凭据。即使在我对另一个用户进行身份验证之后，它似乎仍然具有旧的连接。  以下是我的facebook示例

Facebook控制器

    @Controller
    public class LoginController {
      private Facebook facebook;
      private Google google;
      private ConnectionRepository connectionRepository;

      @Autowired
      private DetailService manager;

      @Autowired
      private UserService users;

      @Autowired
      public LoginController(Facebook facebook, Google google, ConnectionRepository connectionRepository) {
        this.facebook = facebook;
        this.google = google;
        this.connectionRepository = connectionRepository;
      }
         @RequestMapping(value = "/facebookProcessor", method = RequestMethod.POST)
              public String facebookProcessor(Model model) {
                if (connectionRepository.findPrimaryConnection(Facebook.class) == null) {
                  return "redirect:/connect/facebook";
                }

                String email = facebook.userOperations().getUserProfile().getEmail();
                String name = facebook.userOperations().getUserProfile().getName();
                String fbID = facebook.userOperations().getUserProfile().getId();

                if (users.findByUsername(email) == null) {
                  User user = new User();
                  user.setUsername(email);
                  user.setName(name);
                  user.setProvider("faceboob");
                  user.setPassword(fbID);
                  user.setRoles(new String[]{"ROLE_USER"});
                  users.save(user);
                  UserDetails userDetails = manager.loadUserByUsername (user.getUsername());
                  Authentication auth = new UsernamePasswordAuthenticationToken (userDetails.getUsername (),userDetails.getPassword (),userDetails.getAuthorities ());
                  SecurityContextHolder.getContext().setAuthentication(auth);
                }else if(Objects.equals(users.findByUsername(email).getUsername(),email)){
                  UserDetails userDetails = manager.loadUserByUsername (email);
                  Authentication auth = new UsernamePasswordAuthenticationToken (userDetails.getUsername (),userDetails.getPassword (),userDetails.getAuthorities ());
                  SecurityContextHolder.getContext().setAuthentication(auth);
                }

                return "redirect:/entries";
              }
}

SocialConfig

@Configuration
@EnableSocial
public class SocialConfig {
  @Value("${spring.social.google.appId}")
  private String googleAppId;

  @Value("${spring.social.google.appSecret}")
  private String googleAppSecert;

  @Value("${spring.social.facebook.appId}")
  private String facebookAppId;

  @Value("${spring.social.facebook.appSecret}")
  private String facebookAppSecret;

  private ConnectionRepository connectionRepository;

  @Bean
  public ConnectionFactoryLocator connectionFactoryLocator() {
    ConnectionFactoryRegistry registry = new ConnectionFactoryRegistry();
    registry.addConnectionFactory(new GoogleConnectionFactory(
        googleAppId,
        googleAppSecert));
    registry.addConnectionFactory(new FacebookConnectionFactory(
        facebookAppId,
        facebookAppSecret));
    return registry;
  }

}

WebSecurityConfiguration 以防万一..

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
  @Autowired
  DetailService userDetailsService;

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService).passwordEncoder(User.PASSWORD_ENCODER);
  }

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
        .antMatchers("/signup").permitAll()
        .anyRequest().permitAll()
        .and()
        .formLogin()
        .loginPage("/login")
        .permitAll()
        .successHandler(loginSuccessHandler())
        .failureHandler(loginFailureHandler())
        .and()
        .logout()
        .permitAll()
        .logoutSuccessUrl("/login")
        .and()
        .csrf().disable();

    http.headers().frameOptions().disable();
  }

  public AuthenticationSuccessHandler loginSuccessHandler() {
    return (request, response, authentication) -> response.sendRedirect("/");
  }

  public AuthenticationFailureHandler loginFailureHandler() {
    return (request, response, exception) -> {
      response.sendRedirect("/login");
    };
  }

  @Bean
  public EvaluationContextExtension securityExtension() {
    return new EvaluationContextExtensionSupport() {
      @Override
      public String getExtensionId() {
        return "security";
      }

      @Override
      public Object getRootObject() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        return new SecurityExpressionRoot(authentication) {
        };
      }
    };
  }

}
