客户端：jedis-2.7.2.jar

配置文件两种方式：

properties:

redis.cluster.nodes1=192.168.1.117
redis.cluster.port1=7001
redis.cluster.nodes2=192.168.1.117
redis.cluster.port2=7002

redis.cluster.port3=7003
redis.cluster.nodes4=192.168.1.117
redis.cluster.port4=7004
redis.cluster.nodes5=192.168.1.117
redis.cluster.port5=7005
redis.cluster.nodes6=192.168.1.117
redis.cluster.port6=7006
redis.cluster.nodes1=192.168.1.117
redis.cluster.config.max-total=100
redis.cluster.config.max-idle=20
redis.cluster.config.max-waitmillis=-1
redis.cluster.config.onborrow=true
redis.cluster.timeout=6000

@Configuration
//启动缓存配置
