SpringBoot15 sell02 订单模块

1 订单模块

　　1.1 MySQL数据表

　　　　订单模块涉及到两个数据表：

　　　　　　订单表：主要存储订单相关的基本信息

DROP TABLE IF EXISTS `order_master`;
CREATE TABLE `order_master` (
  `order_id` varchar(32) NOT NULL,
  `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(8,2) NOT NULL COMMENT '订单总金额',
  `order_status` tinyint(3) NOT NULL DEFAULT '' COMMENT '订单状态, 默认为新下单',
  `pay_status` tinyint(3) NOT NULL DEFAULT '' COMMENT '支付状态, 默认未支付',
  `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 (`order_id`),
  KEY `idx_buyer_openid` (`buyer_openid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

order_master

　　　　　　订单详情表：主要存放和订单相关的shaping详细信息

DROP TABLE IF EXISTS `order_detail`;
CREATE TABLE `order_detail` (
  `detail_id` varchar(32) NOT NULL,
  `order_id` varchar(32) NOT NULL,
  `product_id` varchar(32) NOT NULL,
  `product_name` varchar(64) NOT NULL COMMENT '商品名称',
  `product_price` decimal(8,2) NOT NULL COMMENT '当前价格,单位分',
  `product_quantity` int(11) NOT NULL COMMENT '数量',
  `product_icon` varchar(512) DEFAULT NULL COMMENT '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`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
