第一步，需要在添加依赖的时候，选中这两个依赖。
第二步，修改配置文件
此处可以用properties也可以用yml。
第三步，完善controller
之前使用jedis，是通过jedis对象里面的各种方法来操作redis的，此处Spring中则是通过StringRedisTemplate来操作redis。
此处的RedisTemplate是把这些操作Redis的方法，分成了几个类别，做了进一步的封装。
比如此处的opsForValue就可以获取到对象，操作字符串类型。
但是，redisTemplate，并不是什么方法都有的，比如我们想要删库，flushAll操作就没有，如果我们想要完成一些原生redis才有的操作，怎么办呢？
RedisTemplate留了一个后手，让我们随时能够执行到原生Redis的命令：execute方法
能够直接在Redis连接上执行命令，这在需要执行复杂或自定义的Redis操作时非常有用。
String List Hash Set Zset
五种类型，大同小异，用法具体来说可以通过官方文档查询。
