Struts2整合Spring Hibernate的CRUD的实例

原帖及讨论：http://bbs.bccn.net/thread-239431-1-1.html

Struts 2 + Spring 2.0 + Hibernate 3.0整合的操作可以参照我的这篇文章 http://bbs.bccn.net/thread-239025-1-1.html
本文提供Struts2整合Spring Hibernate的CRUD的实例的源代码

1. 数据库脚本，数据库采用MySQL 5.0

CREATE TABLE `user` (
`id` int(11) NOT NULL auto_increment,
`username` varchar(32) NOT NULL,
`password` varchar(32) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. 几个重要的文件

3. 本实例仅实现CRUD功能，没有实现其他的处理，如数据校验、国际化、分页等.

4. 由于附件过大，lib下所有的jar都删掉了，请各位学习者按照上一文的操作导入。

附件是ssh2目录结构
