Jedis结合Spring连接Redis集群Clustor
## 方案一：使用RedisTemplate连接单机
这个配置不能连接Clustor集群，只能连接单独的Redis服务器，RedisTemplate是Spring提供的功能，对于Redis数据操作进行了很好的封装，推荐使用：
```
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxTotal" value="${redis.maxTotal}"/>
<property name="maxIdle" value="${redis.maxIdle}" />
<property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
<property name="testOnBorrow" value="${redis.testOnBorrow}" />
<property name="testOnReturn" value="${redis.testOnReturn}"></property>
</bean>
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<constructor-arg index="0" ref="jedisPoolConfig" />
<property name="usePool" value="true"></property>
<property name="hostName" value="${redis.host}" />
<property name="port" value="${redis.port}" />
</bean>
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory"></property>
<property name="keySerializer">
<bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
</property>
<property name="valueSerializer">
<bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
</property>
</bean>
<bean id="redisBase" abstract="true">
<property name="template" ref="redisTemplate" />
</bean>
</beans>
```
redis.properties
```
redis.host=127.0.0.1
redis.port=6379
redis.maxTotal=3000
redis.maxIdle=1000
redis.maxWaitMillis=1500
redis.testOnBorrow=true
redis.testOnReturn=true
```
## 方案二：使用JedisClustor连接集群
这种可以连接RedisClustor集群，使直接使用的Jedis库：
```

不能连接集群，只能连接独立的Redis服务器，Jedis库：
