spring 结合 Redis 例子,简单入门例子

好了费话不多说了,介绍下spring 结合redis是怎么操作数据的这里我用了maven管理,由于简单嘛,依赖下包就行了..不用单独去依赖包,成了我的习惯

好了,下面是pom的代码

pom.xml

在pom里添加了redis spring客户端的依赖,那么所有的jar包都会帮你自动下载下来,是不是很方便啊,哈

这里配置了一个跟spring 集成的redis客户端,ip port password自己定哦,这里我在redis配置文件了定义了需求密码认证,你们先不要用吧,为了简单起见

下面是RedisService,里面包含了对redis的方法,还有更多的方法没有去使用,这里当一个入门的小例子吧
