一、redis配置

　　1、啟動redis

　　這裡使用的是windows版本的redis，直接解壓使用就可以了。

　　　註意1：　當運行redis-server時需要註意的是不同的電腦因為配置問題可能無法雙擊啟動。所以需要通過命令提示符的方式進行啟動

　　這個界面表示redis已經啟動，預設配置 redis.host=localhost redis.port=6379

　　 2、applicationContext-redis.xml配置

<?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"  
    xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"  
    xmlns:aop="http://www.springframework.org/schema/aop"  
    xsi:schemaLocation="  
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">  

     <context:component-scan base-package="com.zhongwu.redis.dao"/> 
    
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxActive" value="50" />
        <property name="maxIdle" value="8" />
        <property name="maxWait" value="1000" />
        <property name="testOnBorrow" value="true"/>
        <property name="testOnReturn" value="true"/>
        <!-- <property name="testWhileIdle" value="true"/> -->
    </bean>

    <bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool"  scope="singleton">
        <constructor-arg index="0" ref="jedisPoolConfig" />
        <constructor-arg index="1">
            <list>
                <bean class="redis.clients.jedis.JedisShardInfo">
                    <constructor-arg name="host" value="localhost" />
                    <constructor-arg name="port" value="6379" />
                    <constructor-arg name="timeout" value="0" />
                    <constructor-arg name="weight" value="1" />
                </bean>
            </list>
        </constructor-arg>
    </bean>
    
</beans>

　　引入jar包，這裡需要註意的是redis版本問題，版本更新中有些參數名稱更改，此處根據applicationContext-redis.xml配置中參數選擇2.1.0版本進行配置。

     <!-- redis -->  
         <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.1.0</version>
        </dependency>

　　3、redis使用相關介面方法
