@Autowired
private JedisCluster jedisCluster;
保存：
byte[] key = SerializeUtil.serialize(buildRedisSessionKey(session.getId()));
jedisCluster.set(SerializeUtil.serialize(buildRedisSessionKey(session.getId())), SerializeUtil.serialize(session));
jedisCluster.expire(key, SESSION_VAL_TIME_SPAN);
删除：
jedisCluster.del(SerializeUtil.serialize(buildRedisSessionKey(id)));
查询：
byte[] value = jedisCluster.get(SerializeUtil.serialize(buildRedisSessionKey(id)));*/
session = SerializeUtil.deserialize(value, Session.class);
以上示例中的key与value都是序列化的，因为保存的是session信息，保存普通对象时可以不序列化。
