spring security，如何使用户的所有会话过期

Question

我必须解决以下场景，在 Spring Security 中3.2.5-RELEASE，Spring Core 4.1.2-RELEASE应用程序在 Wildfly 8.1 上运行 Java 1.7。

1. 用户“鲍勃”登录
2. 管理员删除“bob”
3. 如果“bob”注销，他将无法再次登录，但他当前的会话仍然处于活动状态。

4. 我想把“鲍勃”踢出去

   //this doesn't work
   for (final SessionInformation session :    sessionRegistry.getAllSessions(user, true)) {
            session.expireNow();
   }
   

Answer 1

1. 添加应用程序事件监听器来跟踪HttpSessionCreatedEvent并将HttpSessionDestroyedEvent其注册ApplicationListener为 HttoSession 并维护 SessionId 的缓存。
2. （可选）添加您自己的 ApplicationEvent 类AskToExpireSessionEvent-
3. 在您的用户管理服务中添加依赖项SessionRegistry，ApplicationEventPublisher以便您可以列出当前活动的用户会话并找到您正在寻找的用户（即“bob”）活动的会话（因为可能有很多）
4. 删除用户时，AskToExpireSessionEvent为他的每个会话调度一个。
5. 使用弱引用 HashMap 来跟踪会话

用户服务：

     @Service
     public class UserServiceImpl implements UserService {

      /** {@link SessionRegistry} does not exists in unit tests */
      @Autowired(required = false)
      private Set<SessionRegistry> sessionRegistries;


      @Autowired
      private ApplicationEventPublisher publisher;


     /**
      * destroys all active sessions.
      * @return <code>true</code> if any session was invalidated^
      * @throws IllegalArgumentException
      */
      @Override
      public boolean invalidateUserByUserName(final String userName) {
              if(null == StringUtils.trimToNull(userName)) {
                      throw new IllegalArgumentException("userName must not be null or empty");
              }
              boolean expieredAtLeastOneSession = false;
              for (final SessionRegistry sessionRegistry : safe(sessionRegistries)) {
                      findPrincipal: for (final Object principal : sessionRegistry.getAllPrincipals()) {
                              if(principal instanceof IAuthenticatedUser) {
                                      final IAuthenticatedUser user = (IAuthenticatedUser) principal;
                                      if(userName.equals(user.getUsername())) {
                                              for (final SessionInformation session : sessionRegistry.getAllSessions(user, true)) {
                                                      session.expireNow();
                                                      sessionRegistry.removeSessionInformation(session.getSessionId());
                                                      publisher.publishEvent(AskToExpireSessionEvent.of(session.getSessionId()));
                                                      expieredAtLeastOneSession = true;
                                              }
                                              break findPrincipal;
                                      }
                              } else {
                                      logger.warn("encountered a session for a none user object {} while invalidating '{}' " , principal, userName);
                              }
                      }
              }
              return expieredAtLeastOneSession;
      }

     }

申请活动：

     import org.springframework.context.ApplicationEvent;

     public class AskToExpireSessionEvent extends ApplicationEvent {

             private static final long serialVersionUID = -1915691753338712193L;

             public AskToExpireSessionEvent(final Object source) {
                     super(source);
             }

             @Override
             public String getSource() {
                     return (String)super.getSource();
             }


             public static AskToExpireSessionEvent of(final String sessionId) {
                     return new AskToExpireSessionEvent(sessionId);
             }
     }

             void onHttpSessionCreatedEvent(final HttpSessionCreatedEvent event){
