因为redis3.0才出来，spring-data-redis正式版本还没有支持redis-cluster。大概上官网看了一下，发现只有1.7.0.RC1才支持，同时没有找到关于jedis与spring-data-redis集成RedisTemplate的资料，所以看了一下原码，写了下面关于RedisTemplate的配置。

二、与spring-data-redis集成
1.JedisCluster
以集群方式使用连接池，来直接使用redis相关命令。
spring.xml

</property>

<property name="addressKeyPrefix" value="address" />
<property name="timeout" value="300000" />
<property name="maxRedirections" value="6" />
<property name="genericObjectPoolConfig" ref="jedisPoolConfig" />
</bean>

2.RedisTemplate
以集群方式使用连接池，来使用模板进行数据操作，key与value自动序列化存储。

<property name="testOnReturn" value="${redis.testOnReturn}" />
</bean>

spring-data-redis提供了多种serializer策略，这对使用jedis的开发者而言，实在是非常便捷。sdr提供了4种内置的serializer：
JdkSerializationRedisSerializer：使用JDK的序列化手段(serializable接口，ObjectInputStrean，ObjectOutputStream)，数据以字节流存储
StringRedisSerializer：字符串编码，数据以string存储
JacksonJsonRedisSerializer：json格式存储
OxmSerializer：xml格式存储
其中JdkSerializationRedisSerializer和StringRedisSerializer是最基础的序列化策略，其中“JacksonJsonRedisSerializer”与“OxmSerializer”都是基于stirng存储，因此它们是较为“高级”的序列化(最终还是使用string解析以及构建java对象)。
RedisTemplate中需要声明4种serializer，默认为“JdkSerializationRedisSerializer”：
1) keySerializer ：对于普通K-V操作时，key采取的序列化策略
2) valueSerializer：value采取的序列化策略
3) hashKeySerializer： 在hash数据结构中，hash-key的序列化策略
4) hashValueSerializer：hash-value的序列化策略
无论如何，建议key/hashKey采用StringRedisSerializer。

redis4CacheTemplate.opsForValue().set("cc", "AA1");
redis4CacheTemplate.opsForValue().set("t4", "BB");
System.out.println(redis4CacheTemplate.opsForValue().get("aa"));
System.out.println(redis4CacheTemplate.opsForValue().get("cc"));
System.out.println(redis4CacheTemplate.opsForValue().get("t44"));
