redis是一种非关系型数据库，与mongoDB不同的是redis是内存数据库，所以访问速度很快。常用作缓存和发布-订阅式的消息队列。redis官方没有提供windows版本的软件。windows版本一直是微软维护的。

在spring中集成redis很简单，这里用的是ssm框架+maven构建的项目。
首先是需要引入的pom.xml文件：

缓存主要在service层进行，查询的结果会缓存，把对象序列号存到redis中去，key就是注解中的参数，例如@Cacheable("findUsers"): 存在redis中的key就是findUsers。缓存了这个结果之后再次请求这个方法就不会去数据库中查，而是从redis缓存中读取数据，这样就减少了跟数据库之间的交互。然后修改、删除、增加操作就会清除缓存，保持数据的一致性。
RedisCacheConfig: 需要增加这个配置类，会在applicationContex配置文件中注册这个bean。
