本文深入解析了京东购物车的实现思路，涵盖Cookie与Redis存储方案、前后端代码编写及需求分析。阐述了本地购物车与远程购物车的融合机制，以及如何在不同登录状态下处理购物车数据。
课程目标
- 说出京东购物车的实现思路
- 运用Cookie储存购物车
- 编写购物车前端代码
- 运用Redis存储购物车
购物车需求分析与解决方案
-
需求分析：
- 用户在商品详细页点击加入购物车，提交商品SKU编号和购买数量，添加到购物车；
-
架构图分析：
-
存储方案：
- 当用户没有登录：采用cookie存储 [本地购物车]
- 当用户登录后，采用redis存储，并且要将cookie中的购物车合并到redis中，cookie中的购物车清空； [远程购物车]
-
cookie购物车存储逻辑：
-
注意：
- 不是所有的逻辑层必须写在service层，但是写在service一方面是解耦合分工明确，一方面方便共用，前端的controller.js和service.js也是如此；
购物车解决方案思路：
1. 建好相关包，导入相关依赖和配置文件；
2. interface:
1. 分析：
* 在电商项目中，购物车是一个必须要做的东西；首先从购物车的角度来讲，我们有商品，那么就有购物车，购物车里面包含很多个商品，每个商品又有各自的属性，同时整个购物车也应该包含商家信息；所以应该架构为：
1. 购物车列表：[商家信息]与[商品明细]
2. 商品明细：[商品的标题，价格，数量等]
* 所以在建interface时创建方法应该有：添加单个商品到购物车，[删除的操作可以在前端实现]
* 同时应该要考虑到一些用户没有登录的时候，应该也能使用购物车功能，所以应该有两种购物车方式：一种是本地购物车[cookie]，一种是远程购物车[redis]
* 如此，在Interface中应该再添加两个方法，一个是存储购物车到cookie,一个是存储购物车到redis;
* 如果用户一开始没有登录，但是已经添加了部分商品，后来又登录了，应该将以前的远程购物车中的商品与cookie中的商品同时存储起来，并将本地购物车中的商品删除；
2. 方法：
1. 添加购物车到商品列表
2. 从redis中提取购物车列表
3. 将购物车列表存入redis
4. 合并购物车
2. service:
1. 分析：
* 首先应该有查询方法： 根据SKU id查询商品明细的SKU对象，如果对象不存在抛出异常，如果存在，则先由商品的id值找到商家对象，判断商家对象是否为null，如果购物车中不存在商家的购物车，说明这是在这家店买的第一件商品，应该新建立一个购物车对象，存入商家的信息和商品明细信息，并添加到总购物车中；
* 如果该商家对象存在，说明在总购物车中已经添加了一些该商家的商品了，这时候应该要考虑该商品是否跟已经添加的商品一样，如果是一样的，应该更新数量和金额，因为重复添加，金额应该增加，商品数量也应该增加；如果不是一样的，应该建立一个新的明细对象，然后将这个商品明细添加到用户的购物车中的这个商家购物车中；
* 考虑到商品增加要更新金额和数量，如果商品数量为0，说明用户不想买了，此时应该将商品删除，如果最终该商家在该购物车列表中没有商品，那么就应该将该商家的购物车删除掉；
* 同时应该提供从redis中提取购物车列表的方法，从redis中存入购物车列表的方法，合并购物车的方法；
* 应该将查询的部分功能拆分，既可以复用又避免代码臃肿，所以应该提取出一个方法：根据商家id在购物车列表中查询购物车对象
2. 方法：
1. 添加购物车方法
2. 根据商家id查询购物车方法
3. 向redis中存入购物车列表
4. 从redis中提取购物车列表
5. 合并购物车方法
3. web：
1. 分析：
* 注入service的方法的时候，使用@Reference方法，可以加个timeout=6000防止超时；
* 查询购物车的时候，可以通过获取当前登录人名字判断，因为使用绿卡政策[anonymousUser匿名登录]：anonymousUser[未登录]，账户名[已登录]进行判断，如果是未登录则从cookie中提取购物车，如果是已登录则从redis中获取购物车列表；
* 从redis中获取购物车列表的时候，应该判断本地是否存在数据以提高性能[不判断的时候每次调用此方法都会合并操作],如果第一次从redis中提取的话，应该将本地的购物车合并并将本地购物车的数据进行删除；
* 添加购物车列表，应该也获取登录名以判断是否登录，如果未登录应该存入cookie,如果已经登录，存入redis；
