struts2.0+spring2.0 + hibernate 3.2 結合開發Web應用帶來了很多改進,更多的是配置引數.以下結合開發專案說明如何使用struts2.0+spring2.0+hibernate3.2開放


資料庫 oracle 9i/10g

包結構
cn.nlinux.test.action 放置 struts 2.0 action
cn.nilnux.test.bo 放置BO
cn.nlinux.test.bo.hbms 放置hibernate3 的資料表 配置檔案
cn.nlinux.test.business PO介面
cn.nlinux.test.business.service PO實現
cn.nlinux.test.dao DAO介面
cn.nlinux.test.dao.hibernate DAO實現



配置applicationContext.xml
