Usage

From source file:net.eggcanfly.spring.shiro.support.RedisSessionDao.java

protected Session deserializeSession(Serializable sessionId) {

    BoundHashOperations<String, String, Object> hashOperations = redisTemplate
            .boundHashOps(SESSION_KEY + sessionId);

    SimpleSession session = new SimpleSession();

    try {/*  w w w  . j  a v  a 2 s  .c  o m*/

        session.setHost((String) hashOperations.get("host"));
        session.setId(sessionId);
        session.setLastAccessTime(
                hashOperations.get("lastAccessTime") == null ? new Date(System.currentTimeMillis())
                        : (Date) hashOperations.get("lastAccessTime"));
        session.setStartTimestamp((Date) hashOperations.get("startTimestamp"));
        session.setStopTimestamp((Date) hashOperations.get("stopTimestamp"));
        session.setTimeout((long) hashOperations.get("timeout"));
        Set<String> hashKeys = hashOperations.keys();
        for (Iterator<String> iterator = hashKeys.iterator(); iterator.hasNext();) {
            String hashKey = iterator.next();
            session.setAttribute(hashKey, hashOperations.get(hashKey));
        }
    } catch (Exception e) {
        logger.error(e.getMessage(), e);

    }

    logger.debug("read session " + sessionId + ", session is " + session);

    return session.isValid() ? session : null;
}
