【苍穹外卖】Day 7 地址簿、下单、定时处理

1 地址簿模块

地址簿实体对象：

package com.sky.entity;import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;/*** 地址簿*/
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class AddressBook implements Serializable {private static final long serialVersionUID = 1L;private Long id;//用户idprivate Long userId;//收货人private String consignee;//手机号private String phone;//性别 0 女 1 男private String sex;//省级区划编号private String provinceCode;//省级名称private String provinceName;//市级区划编号private String cityCode;//市级名称private String cityName;//区级区划编号private String districtCode;//区级名称private String districtName;//详细地址private String detail;//标签private String label;//是否默认 0否 1是private Integer isDefault;
}

数据库地址簿表

1.1 Path 和 Method 设计

1.3 测试

2 下单

为什么两张表：

订单表是描述订单的

订单明细表是描述订单里面的商品
