整合思路
将工程的三层结构中的javabean分别使用spring容器(通过xml方式)进行管理。
- 整合持久层mapper，包括数据源、会话工程及mapper代理对象的整合；
- 整合业务层service，包括事务及service的bean的配置；
- 整合表现层controller，直接使用springmvc的配置；
- web.xml加载spring容器(包含多个xml文件)；
spring 核心配置文件：
- applicationcontext-dao.xml
- applicationcontext-service.xml
- springmvc.xml
需求分析
表现层
请求url:/queryitem
请求参数：无
请求返回值：modelandview指定model和view(item-list.jsp)
request域(model)：key为itemlist
业务层
业务处理逻辑(需求分析)：实现商品列表的查询
持久层
只针对表进行查询
工程搭建
依赖包
- spring(包括springmvc)
- mybatis
- mybatis-spring整合包
- 数据库驱动
- 第三方连接池
- jstl
- servlet-api
