1.1.MVC介绍
MVC是一种设计模式将软件按照模型、视图、控制器来划分 MModel模型层指工程中的JavaBean作用是处理数据 JavaBean分为两类 一类称为数据承载Bean专门存储业务数据的如 Student、User 等 一类称为业务处理Bean指 Service 或 Dao 对象专门用于处理业务逻辑和数据访问。 VView视图层指工程中的html或jsp等页面作用是与用户进行交互展示数据 CController控制层指工程中的servlet作用是接收请求和响应浏览器
MVC的工作流程
用户通过视图层发送请求到服务器在服务器中请求被Controller接收Controller调用相应的Model层处理 请求处理完毕将结果返回到ControllerController再根据请求处理的结果找到相应的View视图渲染数据 后最终响应给浏览器
MVC与三层架构的关系
三层架构的分层模式是典型的上下关系上层依赖于下层。但MVC作为表现模式是不存在上下关系的而是相互协作关系。
三层是基于业务逻辑来分的而mvc是基于页面来分的。

1.2.Spring MVC介绍 Spring MVC 是Spring框架的一个模块是一个基于 MVC 设计模式的轻量级 Web 开发框架本质上相当于 Servlet。 SpringMVC 是 Spring 为表示层开发提供的一整套完备的解决方案。在表述层框架历经 Strust、WebWork、Strust2 等诸多产品的历代更迭之后目前业界普遍选择了 SpringMVC 作为 Java EE 项目表述层开发的首选方案。
2.SpringMVC 的入门
2.1.环境搭建
2.1.1.创建工程 2.1.2.添加web支持 右键项目选择Add framework support...
2.添加web支
3.效果 注意 不要先添加打包方式 将web目录要拖拽到main目录下并改名为webapp
2.1.3.pom.xml
