总体介绍
承接着我们的springmvc+mybatis+mysql初级高级课程,以Dept部门模块做一个微服务通用案例
Consumer消费者(Client)通过REST调用Provider提供者(Server)提供的服务
Maven的分包分模块架构复习
一个简单的Maven模块结构是这样的:
springcloud父工程(Project)下初次带着3个子模块(Module)

80端口是为HTTP(HyperText Transport Protocol)即超文本传输协议开放的
此为上网冲浪使用次数最多的协议,主要用于WWW(World Wide Web)即万维网传输信息的协议。
可以通过HTTP地址(即常说的"网址")加":80"来访问网站,
因为浏览网页服务默认的端口号都是80,因此只需输入网址即可,不用输入":80"了。
