<p style="margin: 0px 0px 1.2em !important; font-size: 16px; line-height: 1.75em; padding-right: 0.5em; padding-left: 0.5em;">MVC全名是Model View Controller，是模型(model)－视图(view)－控制器(controller)的缩写

数据库中存取数据。
• 显示的部分，即我们所看到的html前端网页。
• 用户交互的部分，即根据用户输入的url，映射相应的函数，调用model处理数据等的业务逻辑处理。

• 页面展示给用户，对应MVC中的view。
• 调用Model和Template。

一个url分发器，用来根据用户输入的不同url，来调用不同的view函数。url分发器和View组合对应着MVC中的Controller
