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" 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">

3.将shardedJedisPool注入相关的类中即可使用
