Redis服务器的部署方式可分为单机和集群的方式,使用Jedis的对应访问接口也相应不用。如何使用Jedis操作两种不同部署方式的Redis数据,以及在web工程里如何快速的切换两种不同的访问方式,是本文要介绍的主要内容。
本示例使用的相关框架版本如下:
Jedis:jedis-2.8.1
spring:spring 4.0.8
涉及的主要类图如下:
JedisClient与JedisClsterClient都实现了IJedisClinet接口,接口里定义了操作redis的各种方法,这两个Client实现类分别对应着单机和集群两种访问方式。RedisOperate类是供其它类调用的Redis操作类,它持有IJedisClient接口的实现类对象,这个对象由spring注入,具体使用哪种连接方式取决于注入的IJedisClient的实现类类型。这里使用的是策略模式。
JedisClusterFactory实现了org.springframework.beans.factory.FactoryBean和org.springframework.beans.factory.InitializingBean接口,用于为JedisClusterClient提供redis.clients.jedis.JedisCluster操作类。JedisClient的操作类是redis.clients.jedis.Jedis,从redis.clients.jedis.JedisPool类中获取。
Spring的配置如下:
Jedis Configuration
127.0.0.1:7000
127.0.0.1:7001
127.0.0.1:7002
在进行单机、集群切换时,只需要修改
下面看看代码:
