struts2.0+spring2.0 + hibernate 3.2 结合开发Web应用带来了很多改进,更多的是配置参数.以下结合开发项目说明如何使用struts2.0+spring2.0+hibernate3.2开放

数据库 oracle 9i/10g

包结构
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 的数据表 配置文件
cn.nlinux.test.business PO接口
cn.nlinux.test.business.service PO实现
cn.nlinux.test.dao DAO接口
cn.nlinux.test.dao.hibernate DAO实现

配置applicationContext.xml
