学了springcloud如何操作数据库进行增删改查,又学了springcloud如何操作reids把数据存储到redis。今天结合数据库操作和reids操作,来看看如何使用SpringCache。SpringCache提供了基于注解的缓存配置方法。它本质上不是一个具体的缓存实现方案(例如EHCache),而是一个对缓存使用的抽象和封装,通过在已有代码中打上几个预定义的注释,就可以实现希望达到的缓存效果。SpringCache支持跟第三方缓存例如EHCache、Redis集成;另外也提供了开箱即用的默认实现,可以直接拿来使用。SpringCache支持使用SpEL(Spring ExpressionLanguage)来定义缓存的key和各种condition,因此具备相当的灵活性,并可以支持非常复杂的语义。
1、新建项目sc-redis-cache,对用的pom.xml文件如下
