#### 基础数据构建

项目结构：**前后端分离架构，容器编排部署**

独立数据库：

- 用户服务数据库： p_nla_user   (Project_New Lead Acquisition_User 拉新营销项目用户数据库）
- 商品服务数据库： p_nla_product
- 优惠券服务数据库： p_nla_coupon
- 订单服务数据库： p_nla_order

用户服务数据库中创建表：`user`、`address`

用户表

```sql
CREATE TABLE `user` (
 `id` bigint(11) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(128) DEFAULT NULL COMMENT '昵称',
 `pwd` varchar(124) DEFAULT NULL COMMENT '密 码',
 `head_img` varchar(524) DEFAULT NULL COMMENT '头像',
 `slogan` varchar(524) DEFAULT NULL COMMENT '用户签名',
 `sex` tinyint(2) DEFAULT '1' COMMENT '0-女，1-男',
 `points` int(10) DEFAULT '0' COMMENT '积 分',
 `create_time` datetime DEFAULT NULL,
 `mail` varchar(64) DEFAULT NULL COMMENT '邮 箱',
 `secret` varchar(12) DEFAULT NULL COMMENT '盐，用于个人敏感信息处理',
  PRIMARY KEY (`id`),
  UNIQUE KEY `mail_idx` (`mail`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT
CHARSET=utf8;
```

收货地址表

```sql
CREATE TABLE `address` (
 `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
 `user_id` bigint(20) DEFAULT NULL COMMENT '用户id',
 `default_status` int(1) DEFAULT NULL COMMENT '是否默认收货地址：0-否；1-是',
 `receive_name` varchar(64) DEFAULT NULL COMMENT '收发货人姓名',
 `phone` varchar(64) DEFAULT NULL COMMENT '收货人电话',
 `province` varchar(64) DEFAULT NULL COMMENT '省/直辖市',
 `city` varchar(64) DEFAULT NULL COMMENT '市',
 `region` varchar(64) DEFAULT NULL COMMENT '区',
 `detail_address` varchar(200) DEFAULT NULL COMMENT '详细地址',
 `create_time` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=39 DEFAULT
CHARSET=utf8mb4 COMMENT='电商-公司收发货地址表';
```

#### 技术选型

- SpringCloud
  - 通信方式：http restful
  - 注册中心：eureka
  - 配置中心：config
  - 断路器：hystrix
  - 网关：zuul/gateway
  - 分布式追踪系统：sleuth+zipkin
- Spring Cloud Alibaba
  - 通信方式：http restful
  - 服务注册发现：Nacos
  - 服务限流降级：Sentinel
  - 分布配置中心：Nacos
  - 服务网关：SpringCloud Gateway
  - 服务之间调用：Feign、Ribbon
  - 链路追踪：Sleuth+Zipkin

SpringCloud很多组件是基于第三方整合，`⽬前多个已经不更新了`，比如zuul、eureka、hystrix等

版本选择：

- SpringBoot 2.3.3.RELEASE 版本
- Spring Cloud Hoxton.SR8 版本
- AlibabaCloud 2.2.1.RELEASE 版本
