摘要: Redis服务器的部署方式可分为单机和集群的方式，使用Jedis的对应访问接口也相应不用。如何使用Jedis操作两种不同部署方式的Redis数据，以及在web工程里如何快速的切换两种不同的访问方式，是本文要介绍的主要内容。
Redis服务器的部署方式可分为单机和集群的方式，使用Jedis的对应访问接口也相应不用。如何使用Jedis操作两种不同部署方式的Redis数据，以及在web工程里如何快速的切换两种不同的访问方式，是本文要介绍的主要内容。
本示例使用的相关框架版本如下：
Jedis:jedis-2.8.1
spring:spring 4.0.8
涉及的主要类图如下：
JedisClient与JedisClsterClient都实现了IJedisClinet接口，接口里定义了操作redis的各种方法，这两个Client实现类分别对应着单机和集群两种访问方式。RedisOperate类是供其它类调用的Redis操作类，它持有IJedisClient接口的实现类对象，这个对象由spring注入，具体使用哪种连接方式取决于注入的IJedisClient的实现类类型。这里使用的是策略模式。
JedisClusterFactory实现了org.springframework.beans.factory.FactoryBean和org.springframework.beans.factory.InitializingBean接口，用于为JedisClusterClient提供redis.clients.jedis.JedisCluster操作类。JedisClient的操作类是redis.clients.jedis.Jedis，从redis.clients.jedis.JedisPool类中获取。
Spring的配置如下：
<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"default-lazy-init="true"><description>Jedis Configuration</description> <!-- 加载配置属性文件 --><context:property-placeholder ignore-unresolvable="true" location="classpath:jeeplus.properties" /> <!-- redis 单机连接方案 --><bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"><property name="maxIdle" value="300" /> <!-- 最大能够保持idel状态的对象数 --><property name="maxTotal" value="60000" /> <!-- 最大分配的对象数 --><property name="testOnBorrow" value="true" /> <!-- 当调用borrow Object方法时，是否进行有效性检查 --></bean><bean id="jedisPool" class="redis.clients.jedis.JedisPool"><constructor-arg index="0" ref="jedisPoolConfig" /><constructor-arg index="1" value="${redis.host}" /><constructor-arg index="2" value="${redis.port}" type="int" /></bean><!-- redis 集群连接方案 --><bean name="genericObjectPoolConfig" class="org.apache.commons.pool2.impl.GenericObjectPoolConfig"> <property name="maxWaitMillis" value="-1" /> <property name="maxTotal" value="8" /> <property name="minIdle" value="0" /> <property name="maxIdle" value="8" /> </bean> <bean id="jedisCluster" class="com.jeeplus.common.redis.JedisClusterFactory"> <property name="connectionTimeout" value="3000" /> <property name="soTimeout" value="3000" /> <property name="maxRedirections" value="5" /> <property name="genericObjectPoolConfig" ref="genericObjectPoolConfig" /> <property name="jedisClusterNodes"> <set> <value>127.0.0.1:7000</value> <value>127.0.0.1:7001</value> <value>127.0.0.1:7002</value> </set> </property> </bean> <!-- 真正的redis操作类，具体连接方式由jedisClient的ref属性决定 可选项为jedisClusterClient、jedisClient --> <bean name="redisOperate" class="com.jeeplus.common.redis.RedisOperate"> <property name="jedisClient" ref="jedisClusterClient" /> </bean> </beans>在进行单机、集群切换时，只需要修改<property name="jedisClient" ref="jedisClusterClient" /> 配置即可。
下面看看代码：
