spring-data-redis实战
spring-data-redis版本1.4.0.RELEASE之后引入了sentinel;
spring-data-redis版本1.4.0.RELEASE之后对于spring的依赖版本>=4.0.7.RELEASE;
spring-data-redis版本1.4.0.RELEASE之前不支持sentinel;
spring-data-redis版本1.4.0.RELEASE之前对于spring的依赖版本<=3.2.10.RELEASE;
jedis-2.8不支持Redis-cluster部署方式中集群设置密码访问;
jedis-2.9开始支持redis-cluster部署方式中集群设置密码访问;
spring-data-redis版本1.7.x不支持redis-cluster部署方式集群设置密码访问;
spring-data-redis版本1.8.x开始支持redis-cluster部署方式集群设置密码访问;
1.为什么选择spring-data-redis?
spring-data-redis已经对jedis、jredis进行了封装,完美兼容redis sentinel部署模式、兼容redis-cluster部署模式、单节点redis部署模式,提供统一的API(RedisTemplate)来调用不同的部署模式,完全不用担心redis部署模式变化导致redis客户端代码做调整
1)单节点部署模式
单节点部署模式时与spring、spring-data-redis集成文件如下:
2)sentinel部署模式
sentinel部署模式时与spring、spring-data-redis集成文件如下:
注意:上面IP和端口只需配置sentinel节点的IP和端口,sentinel采用投票方式进行故障切换,而投票方式下原则是少数服从多数,所以sentinel一般至少是3台,上面是我部署的3台sentinel节点的IP和端口。
3)redis-cluster部署模式
redis-cluster部署模式时与spring、spring-data-redis集成文件如下:
2.使用spring-data-redis时比较纠结的与jedis整合版本问题
spring-data-redis版本1.4.0.RELEASE之后引入了sentinel;
spring-data-redis版本1.4.0.RELEASE之后对于spring的依赖版本>=4.0.7.RELEASE;
spring-data-redis版本1.4.0.RELEASE之前不支持sentinel;
spring-data-redis版本1.4.0.RELEASE之前对于spring的依赖版本<=3.2.10.RELEASE;
这个没啥好纠结的,使用什么版本的spring-data-redis就查询这个版本使用的jedis,一种比较靠谱的查询方法是登录http://search.maven.org/ 进行查询,如下:
这里我使用的是最新的1.7.5.RELEASE版本,点击上图pom链接进去搜索jedis,即可查看到jedis版本,如下:
所以最后我的maven依赖如下:
redis.clients jedis 2.8.1 org.springframework.data spring-data-redis 1.7.5.RELEASE

上面问题主要解决办法是将spring版本升级,之前我用的spring版本是4.1.6.RELEASE,将其版本升级到4.3.34.RELEASE后问题解决,而不是网上所说的将jedis版本降级到2.6.2
