SSM框架整合 详细步骤(备注) 附源码
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
