ssm框架的介绍

        ssm框架是Spring MVC，Spring和Mybatis框架的整合，是标准的MVC（model，view，controller）模式。其将整个系统划分为表示层，控制层，业务层，持久层四个层次，使用Spring MVC负责请求的转发和视图管理 （Spring实现业务对象管理，Mybatis作为数据对象的持久化引擎）,ssm框架是目前比较主流的JavaEE企业级框架，适用于搭建各种大型的企业级应用系统。

ssm框架的各层次的介绍

        持久层（Mybatis）：Dao层（mapper）

        主要是做数据持久层的工作，负责与数据库进行联络的一些任务都封装在这里。Dao层作为接口层，在Spring的配置文件中定义接口实现类就可以在模块中调用此接口进行数据业务的处理，不需要关系具体的实现类，Dao层数据得到配置以及相关数据库的参数配置都在Spring中进行配置。

 

        业务层（Spring）：Service

        主要进行模块的逻辑应用设计。添加其接口和对应的实现类，在Spring配置文件中配置其先关得到关联，则可以在应用中调用Service接口进行业务处理，封装其业务逻辑可独立重复的使用，Service层调用Dao层接口。

        控制层（SpringMVC）：Controller层（Hander层）

        主要负责业务模块流程的控制。控制层的配置也需要在Spring文件中配置，针对具体的业务流程，会有不同的控制器，Controller层调用Service层的接口实现控制业务管理。

        视图层：Viwe层

        主要负责调用前台jsp页面的表示。此层与Controller层结合紧密。

ssm环境配置

        1，开启idea，创建一个maven项目，将其变成一个web项目，在src包名下创建一个java，resources包（右键将其分别创建为Sources Root；Resources Root包如下：）

        2，搭建Controller，service，Dao，Domain层：

        3，在添加Spring相关的配置
