sms-server

POM.XML，由于项目主要是用来发短信服务的，所以其他依赖包加上也无妨，不影响
打war包的方式如下面所示

Application 不能放在java.main的根目录，必须建一个目录存放不然保错
它会自动扫描它所在目录下的子目录的相关注解

运行Application main方法

刷新两次浏览器，可以看到控制台打印如下
http://localhost:8081/city?id=1

CityServiceImpl.findCityById() : 城市插入缓存 >> 空城CityServiceImpl.findCityById() : 从缓存中获取了城市 >> 空城

可以在redis desktop manager 刷新看到数据已经插入进来了
