Hibernate学习
一.项目介绍
这个项目是在我学了struts2和hibernate3之后做的，是用这两个框架整合的，分别有表单提交请求，Ajax提交请求，通过Get和Post方式提交，所以这个项目有三大块，表单用Get方式提交请求，表单用Post方式提交请求，Ajax提交请求。
二.项目目录结构
三.需要的JAR包
这是我用的所有JAR包，可以自己去官网上下载struts2和hibernate的压缩包，在lib目录里有JAR包，如果不想自己下载，我上传了资源可以去下载，地址：https://download.youkuaiyun.com/download/sun_ting_chuan/10830515.
四.详细代码
1.表单用get方式提交请求（Post与Get方式提交代码一样，只是提交方式不一样，在这里只写Get方式提交的代码）
