篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了基于XML配置方式SSM框架西蒙购物网相关的知识,希望对你有一定的参考价值。
一、数据库准备
1、创建数据库 - simonshop
2、创建用户表 - t_user
- 创建表
CREATE TABLE `t_user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(20) NOT NULL,
`password` varchar(20) DEFAULT NULL,
`telephone` varchar(11) DEFAULT NULL,
`register_time` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
`popedom` int(11) DEFAULT NULL COMMENT '0:管理员;1:普通用户',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
- 插入表记录
INSERT INTO `t_user` VALUES ('1', 'admin', '12345', '15734345678', '2016-12-02 08:40:35', '0');
INSERT INTO `t_user` VALUES ('2', '郑晓红', '11111', '13956567889', '2016-12-20 09:51:43', '1');
INSERT INTO `t_user` VALUES ('3', '温志军', '22222', '13956678907', '2016-12-20 09:52:36', '1');
INSERT INTO `t_user` VALUES ('4', '涂文艳', '33333', '15890905678', '2016-12-05 09:52:56', '1');
3、创建商品类别表 - t_category
- 创建表

`name` varchar(100) NOT NULL COMMENT '商品类别名称',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
- 插入表记录
INSERT INTO t_category VALUES('1','家用电器');
INSERT INTO t_category VALUES('2','床上用品');
INSERT INTO t_category VALUES('3','文具用品');
INSERT INTO t_category VALUES('4','休闲食品');
4、创建商品表 - t_product
CREATE TABLE `t_product` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '商品标识符',
`name` varchar(200) NOT NULL COMMENT '商品名称',
`price` double DEFAULT NULL COMMENT '商品单价',
`add_time` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
`category_id` int(11) DEFAULT NULL COMMENT '商品类别标识符',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8;
CREATE TABLE `t_product` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '商品标识符',
`name` varchar(200) NOT NULL COMMENT '商品名称',
`price` double DEFAULT NULL COMMENT '商品单价',
`add_time` timestamp NULL DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP,
`category_id` int(11) DEFAULT NULL COMMENT '商品类别标识符',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8;
- 插入表记录
INSERT INTO `t_product` VALUES ('1', '容声电冰箱', '2000', '2016-12-20 09:54:41', '1');
INSERT INTO `t_product` VALUES ('2', '松下电视', '5000', '2016-12-20 09:54:35', '1');

- 最终表
二、项目实现
1、创建Maven项目
2、添加依赖
