Redis集群中SessionDestroyedEvent未接收到会话过期事件

需要使用RedisOperationsSessionRepository，并设置RedisSessionExpirationPolicy以接收session过期事件。

示例代码：

@Configuration @EnableWebHttpSession public class HttpSessionConfig {

@Bean public JedisConnectionFactory connectionFactory() { return new JedisConnectionFactory(); }

@Bean public RedisOperationsSessionRepository sessionRepository(RedisConnectionFactory redisConnectionFactory) { RedisOperationsSessionRepository sessionRepository = new RedisOperationsSessionRepository(redisConnectionFactory); sessionRepository.setRedisKeyNamespace("session:"); sessionRepository.setDefaultMaxInactiveInterval(1800); sessionRepository.setRedisSessionExpirationPolicy(new MapsSessionExpirationPolicy()); return sessionRepository; }

static class MapsSessionExpirationPolicy implements RedisSessionExpirationPolicy {

   private final Map<String, Long> expirationHandlers = Collections
           .synchronizedMap(new HashMap<String, Long>());

   @Override
   public void onDelete(String sessionId) {
       expirationHandlers.remove(sessionId);
   }

   @Override
   public void onExpirationUpdated(Long expirationTimeInSeconds, String sessionId) {
       expirationHandlers.put(sessionId, expirationTimeInSeconds);
   }

   @Override
   public Map<String, Long> getExpirationHandlers() {
       return Collections.unmodifiableMap(expirationHandlers);
   }

} }
