Spring Boot微信点餐——数据库设计

数据库设计：

具体代码如下:

create table `product_info` (
    `product_id` varchar(32) not null comment ‘商品ID‘,
    `product_name` varchar(64) not null comment ‘商品名称‘,
    `product_price` decimal(10,2) not null comment ‘商品单价‘,
    `product_stock` int not null comment ‘库存‘,
    `product_des` varchar(64) comment ‘描述‘,
    `product_icon` varchar(512) comment ‘产品图标‘,
    `category_type` int not null comment ‘类目编号‘,
    `create_time` timestamp not null default current_timestamp comment ‘创建时间‘,
    `update_tiem` timestamp not null default current_timestamp on update current_timestamp comment ‘修改时间‘,
    primary key (`product_id`)
) comment ‘商品表‘;

create table `product_category` (
    `category_id` int not null auto_increment comment ‘类目ID‘,
    `category_name` varchar(64) not null comment ‘类目名称‘,
    `category_type` int not null comment ‘类目编号‘,
    `create_time` timestamp not null default current_timestamp comment ‘创建时间‘,
    `update_tiem` timestamp not null default current_timestamp on update current_timestamp comment ‘修改时间‘,
    primary key (`category_id`),
    unique key `uqe_category_type` (`category_type`)
) comment ‘类目表‘;

create table `order_master` (
    `order_id` varchar(32) not null comment ‘订单ID‘,
    `buyer_name` varchar(32) not null comment ‘买家名字‘,
    `buyer_phone` varchar(32) not null comment ‘买家电话‘,
    `buyer_address` varchar(128) not null comment ‘买家地址‘,
    `buyer_openid` varchar(64) not null comment ‘买家微信openId‘,
    `order_amount` decimal(10,2) not null comment ‘订单总金额‘,
    `order_status` tinyint(3) default ‘0‘ not null comment ‘订单状态，默认为已下单‘,
    `pay_status` tinyint(3) not null default ‘0‘ comment ‘支付状态, 默认未支付‘,
    `create_time` timestamp not null default current_timestamp comment ‘创建时间‘,
    `update_tiem` timestamp not null default current_timestamp on update current_timestamp comment ‘修改时间‘,
    primary key (`order_id`),
    key `idx_buyer_openid` (`buyer_openid`)
) comment ‘订单表‘;

create table `order_detail` (
    `detail_id` varchar(32) not null comment ‘订单详情ID‘,
    `order_id` varchar(32) not null comment ‘订单ID‘,
    `product_id` varchar(32) not null comment ‘商品ID‘,
    `product_name` varchar(64) not null comment ‘商品名称‘,
    `product_price` decimal(10,2) not null comment ‘当前价格,单位分‘,
    `product_quantity` int not null comment ‘商品数量‘,
    `product_icon` varchar(512) comment ‘商品小图‘,
    `create_time` timestamp not null default current_timestamp comment ‘创建时间‘,
    `update_time` timestamp not null default current_timestamp on update current_timestamp comment ‘修改时间‘,
    primary key (`detail_id`),
    key `idx_order_id` (`order_id`)
) comment ‘订单详情表‘;

后期可能会有，用户表和商家表。目前只是一个简单的流程。
