Redis cache access monitoring, operation and maintenance platform CacheCloud

CacheCloud CacheCloud Redis provides a cloud management platform: to achieve a variety of types (Redis Standalone, Redis Sentinel, Redis Cluster) automatically deploy to address the phenomenon of fragmentation Redis instance, to provide comprehensive statistics, monitoring, operation and maintenance function, reduce operation and maintenance costs and misuse improve the utilization of the machine, provides flexible scalability, provides convenient access client.

改造RedisConnectionFactory

/**

 * 示例是单机模式。

@Bean
