ssm框架整合

1)Dao层

           pojo和映射文件以及接口使用逆向工程生成

           SqlMapConfig.xml   mybatis核心配置文件

           ApplicationContext-dao.xml 整合后spring在dao层的配置

                 数据源

                 会话工厂

                 扫描Mapper

2)service层

           事务                ApplicationContext-trans.xml

           @Service注解扫描   ApplicationContext-service.xml

3)controller层

           SpringMvc.xml

                 注解扫描:扫描@Controller注解

                 注解驱动:替我们显示的配置了最新版的处理器映射器和处理器适配器

                 视图解析器:显示的配置是为了在controller中不用每个方法都写页面的全路径

4)web.xml

           springMvc前端控制器配置

           spring监听
