SpringBoot 整合 Redis
SpringBoot 整合 Redis
简单介绍
前面我们基本把Redis 的基本知识介绍完了，但是可以看出，全部都是在SSH命令行操作的，作为一个学习Java的程序员，肯定希望使用Java来操作一把。我们这里直接使用SpringDataRedis来玩，不在单独使用Jedis来操作了。
项目搭建
创建项目
创建项目我们使用 SpringBoot的引导器来创建，这里就不多赘述了。如何创建SpringBoot项目可以参考。

依赖分为两个部分，第一个部分就是jackson-databind,jackson-core,jackson-annotations 关于jackson的几个，第二个部分就是SpringBoot整合redis的staterspring-boot-starter-data-redis 。

这个组件类是以操作List列表创建的，就不单独每一种类型都创建一个了。

测试结果
使用SpringBoot整合Redis就先到这里了。
