1. 一个集成spring+hibernate的简单的Flex工程
2. 从数据库查找指定的用户
=============================================
DB.sql
CREATE TABLE `user` (
`UserID` int(11) NOT NULL auto_increment,
`UserName` varchar(20) default NULL,
`Password` varchar(20) default NULL,
`Email` varchar(20) default NULL,
PRIMARY KEY (`UserID`)
) ENGINE=InnoDB DEFAULT CHARSET=gb2312;

web.xml： 和struts整合spring一样
