Flex+J2EE实例（cairngorm+blazeDS+hibernate+spring） part3
Flex+J2EE实例（cairngorm+blazeDS+hibernate+spring） part3 ----add spring & hibernate
1. 在WEB-INF\lib 下添加 spring 、 hibernate 常用jar,包括mysql数据库的连接驱动
2.在mysql数据库中创建数据库并添加测试数据
语句如下：
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL auto_increment,
`username` varchar(11) NOT NULL default '0',
`password` varchar(11) NOT NULL default '0',
`age` int(11) default '0',
`email` varchar(50) default NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=REDUNDANT;
INSERT INTO `user` VALUES (1,'lww','1234',22,'[email protected]');
INSERT INTO `user` VALUES (2,'xyp','1234',22,'[email protected]');
3.在src 创建以下文件
