1、本文整合实例最终效果图展示

2、导读

2.1、开发技术概述

a.本文使用的是Struts2+Spring+Hibernate框架，Oracle 11g，tomcat-7.0.96，JDK-1.8，MyEclipse10.6，采用了“注解版”的方式开发的；

b.本文所有Hibernate配置文件、dao层、service层、action层等等，统统交给Spring容器来管理；

c.本文只实现了用户登录（含账号查询）、新增用户、查询所有用户信息、根据id查询；

d.通过反射获取子类的泛型实体对象；

e.本项目所采用的编码格式都是 UTF-8；

f.本项目的Struts2和Spring的配置文件都是放在src目录下。

2.2、本项目使用的jar包、项目结构图
