Redis3.0与Jedis2.7.2 客户端与Spring整合
作者：明舞
地址：http://my.oschina.net/91jason/blog/472442
网上一堆jedis2.1.0的配置教程，说实话看到都觉得太老了，而且非常不方便，一般都不做jedis资源的分配和管理，这里公布下我的，可以兼容redis3.0！！！！！！！！！！！！！！！！！！！
1.下载相关jar包，并引入工程：
jedis-2.7.2.jar
commons-pool2-2.0.jar
2.将以下XML配置引入spring
id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool">
"0" ref="jedisPoolConfig"/>
"1">
<list>
name="slaver" class="redis.clients.jedis.JedisShardInfo">
"0" value="${redis.slaver.host}"/>
"1" value="${redis.slaver.port}" type="int"/>
name="master" class="redis.clients.jedis.JedisShardInfo">
"0" value="${redis.master.host}"/>
"1" value="${redis.master.port}" type="int"/>
list>
id="jedisPoolConfig" class="redis.clients.jedis.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"/>
3:properties配置文件：
#数据库jdbc
device.jdbc.url=jdbc:postgresql://127.0.0.1:5432/postgres?charSet=utf-8
device.jdbc.driver=org.postgresql.Driver
device.jdbc.username=postgres
device.jdbc.password=root
#redis缓存配置
redis.slaver.host=127.0.0.1
redis.slaver.port=6379
redis.master.host=127.0.0.2
redis.master.port=63794.将shardedJedisPool注入相关的类中即可使用
