redis+spring配置

pom引入jedis的jar包

address6=192.168.1.248:7005

@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。
