java Redis客户端之Spring整合Jedis

1.下载相关jar包,并引入工程:

jedis-2.4.2.jar

commons-pool2-2.0.jar

2.将以下XML配置引入spring

 <bean id="shardedJedisPool">
        <constructor-arg index="0" ref="jedisPoolConfig"/>
        <constructor-arg index="1">
            <list>
                 <bean name="slaver">
                    <constructor-arg index="0" value="${redis.slaver.host}"/>
                    <constructor-arg index="1" value="${redis.slaver.port}" type="int"/>
                </bean>
                 <bean name="master">
                    <constructor-arg index="0" value="${redis.master.host}"/>
                    <constructor-arg index="1" value="${redis.master.port}" type="int"/>
                </bean>
            </list>
        </constructor-arg>
    </bean>

    <bean id="jedisPoolConfig">
        <property name="maxTotal" value="2048" />
        <property name="maxIdle" value="200" />
        <property name="numTestsPerEvictionRun" value="1024"/>
        <property name="timeBetweenEvictionRunsMillis" value="30000" />
        <property name="minEvictableIdleTimeMillis" value="-1" />
        <property name="softMinEvictableIdleTimeMillis" value="10000" />
        <property name="maxWaitMillis" value="1500"/>
        <property name="testOnBorrow" value="true" />
        <property name="testWhileIdle" value="true"/>
        <property name="testOnReturn" value="false"/>
        <property name="jmxEnabled" value="true"/>
        <property name="jmxNamePrefix" value="youyuan"/>
        <property name="blockWhenExhausted" value="false"/>
    </bean>

3.将shardedJedisPool注入相关的类中即可使用
