端口怎么设置，看我前一篇文章

前面使用jedis，通过Jedis对象中各种方法来操作redis的。

此处Spring中则是通过StringRedisTemplate来操作redis。

最原始提供的类是RedisTemplate

StringRedisTemplate是RedisTemplate的子类，专门处理文本数据的

这个类提供的方法，相比较于Jedis还是有区别的。

做了进一步封装，得到了专门操作字符串的对象，得到了专门操作xx的对象。初心是为了接口更简单。

字符串常用操作

set-get    设置，获取

有些操作封装来，有些没有封装，比如删库，比如ping

RedisTemplate留了一手，让我们随意执行redis的原操作

execute方法，RedisCallback函数式接口，相当于一个回调函数，就在回调里，写我们要执行的redis命令，这个回调就会被RedisTemplate内部进行执行了。

链表常用操作

leftpop和rightpop，头删，尾删

Set常用操作

Hash常用操作

Zset常用操作
