redis+spring配置
pom引入jedis的jar包
<dependency>

<!-- redis jedisCluster集群配置 -->

redis.properties文件内容：
address1=192.168.1.249:7000
address2=192.168.1.249:7001
address3=192.168.1.249:7002
address4=192.168.1.248:7003
address5=192.168.1.248:7004
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。
单个redis配置
