[Flex+J2EE实例（cairngorm+blazeDS+hibernate+spring） part3][Flex_J2EE_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

![0_1329826337bZ7B.gif][]![0_1329826342N7p8.gif][]

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,'lww@qq.com');

INSERT INTO \`user\` VALUES (2,'xyp','1234',22,'xyp@136.com');

3.在src 创建以下文件
