从0开始独立完成企业级Java电商网站开发（服务端）
数据表结构设计
唯一索引unique，保证数据唯一性
CREATE TABLE `mmall_user` ( `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户表id', `username` varchar(50) NOT NULL COMMENT '用户名', `password` varchar(50) NOT NULL COMMENT '用户密码，MD5加密', `email` varchar(50) DEFAULT NULL, `phone` varchar(20) DEFAULT NULL, `question` varchar(100) DEFAULT NULL COMMENT '找回密码问题', `answer` varchar(100) DEFAULT NULL COMMENT '找回密码答案', `role` int(4) NOT NULL COMMENT '角色0-管理员,1-普通用户', `create_time` datetime NOT NULL COMMENT '创建时间', `update_time` datetime NOT NULL COMMENT '最后一次更新时间', PRIMARY KEY (`id`), UNIQUE KEY `user_name_unique` (`username`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8; 复制代码
单索引及组合索引
CREATE TABLE `mmall_order_item` ( `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '订单子表id', `user_id` int(11) DEFAULT NULL, `order_no` bigint(20) DEFAULT NULL, `product_id` int(11) DEFAULT NULL COMMENT '商品id', `product_name` varchar(100) DEFAULT NULL COMMENT '商品名称', `product_image` varchar(500) DEFAULT NULL COMMENT '商品图片地址', `current_unit_price` decimal(20,2) DEFAULT NULL COMMENT '生成订单时的商品单价，单位是元,保留两位小数', `quantity` int(10) DEFAULT NULL COMMENT '商品数量', `total_price` decimal(20,2) DEFAULT NULL COMMENT '商品总价,单位是元,保留两位小数', `create_time` datetime DEFAULT NULL, `update_time` datetime DEFAULT NULL, PRIMARY KEY (`id`), KEY `order_no_index` (`order_no`) USING BTREE, KEY `order_no_user_id_index` (`user_id`,`order_no`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=135 DEFAULT CHARSET=utf8; 复制代码
