SSM框架整合 詳細步驟(備註) 附原始碼
阿新 • • 發佈：2019-11-30
整合思路
將工程的三層結構中的JavaBean分別使用Spring容器(通過XML方式)進行管理。
- 整合持久層mapper，包括資料來源、會話工程及mapper代理物件的整合；
- 整合業務層Service，包括事務及service的bean的配置；
- 整合表現層Controller，直接使用springmvc的配置；
- Web.xml載入spring容器(包含多個XML檔案)；
Spring 核心配置檔案：
- applicationContext-dao.xml
- applicationContext-service.xml
- springmvc.xml
需求分析
表現層
請求URL:/queryItem
請求引數：無
請求返回值：ModelAndView指定Model和View(item-list.jsp)
Request域(Model)：key為itemList
業務層
業務處理邏輯(需求分析)：實現商品列表的查詢
持久層
只針對表進行查詢
工程搭建
依賴包
- spring(包括springmvc)
- mybatis
- mybatis-spring整合包
- 資料庫驅動
- 第三方連線池
- JSTL
- servlet-api
