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
<bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool"> <constructor-arg index="0" ref="jedisPoolConfig"/> <constructor-arg index="1"> <list> <bean name="slaver" class="redis.clients.jedis.JedisShardInfo"> <constructor-arg index="0" value="${redis.slaver.host}"/> <constructor-arg index="1" value="${redis.slaver.port}" type="int"/> </bean> <bean name="master" class="redis.clients.jedis.JedisShardInfo"> <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" 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"/> </bean>3:properties配置文件：
#数据库jdbcdevice.jdbc.url=jdbc:postgresql://127.0.0.1:5432/postgres?charSet=utf-8device.jdbc.driver=org.postgresql.Driverdevice.jdbc.username=postgresdevice.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
