SpringMVC+mybatis+maven+登录注册+增删改查

# 一.SpringMVC #

MVC框架是由Model模型（JavaBean），View视图(Jsp) 和 Controller控制器(Servlet)构成。

其中每一部分的作用为：

1.  Model：承载数据，并对用户提交请求进行计算的模块。其分为两类，一类称为数据承载Bean，一类称为业务处理Bean。所谓数据承载Bean是指实体类，专门承载业务数据的，如Student、User等。而业务处理Bean则是指Service或Dao对象，专门用于处理用户提交请求的。
2.  View：为用户提供使用界面，与用户直接进行交互
3.  Controller：用于将用户请求转发给相应的Model进行处理，并将处理Model的计算结果向用户提供相应响应。

# 二.SpringMVC+mybatis各层关系 #

**Controller层（springMVC）**通过要调用Service层的接口来控制业务流程，负责url映射（action），控制界面跳转。  
**Service层（Spring）**负责业务模块的逻辑应用设计。首先设计其接口，然后再实现他的实现类（Serviceimpl类）。  
通过对Spring配置文件中配置其实现的关联，完成此步工作，我们 就可以通过调用Service的接口来进行业务处理。最后通过调用DAO层已定义的接口，去实现Service具体的实现类。  
**Dao层/Mapper层（Mybatis）**负责与数据库进行交互设计，用来处理数据的持久化工作。DAO层的设计首先是设计DAO的接口，然后在Spring的配置文件中定义此接口的实现类，就可在其他模块中调用此接口来进行数据业务的处理，而不用关心接口的具体实现类是哪个类，这里用到的就是反射机制， DAO层的数据源配置，以及有关数据库连接的参数都在Spring的配置文件中进行配置。  
**View层（视图层）**负责前台jsp页面的展示。
