偏执的太偏执、 2023-09-30 18:27 1阅读 0赞

> #### 该项目开始是要求我们使用JavaWeb(java+jsp+servlet+MySQL+jdbc+css+js+jQuery)实现，但我学过一丢丢的框架，就改用了SpringBoot+Vue实现。 ####
> 
> 注意！！！！！代码中的serverIp我设置的我服务器的IP，所以不在服务器上面应该是localhost！！！！！！！！

## **1. 产品介绍** ##

对于网上商城，其最大好处是要能给用户带来最大的便捷，这种便捷不仅体现在网络之外的物流、商品的折扣等，更要体现在进行网络操作时的易用性，能够模拟用户的购物行为，营造一种尽量真实、贴切的用户购物过程。所以，在设计网络商城时，最重要的就是完成“用户功能”。其次，对众多商品、订单、用户信息的网络管理，对于网站经营者的经营效率的意义，也是不言而喻的，这些则可以称为“管理功能”。

#### 我的购物车： ####

可以勾选商品进行计算价格，然后进行商品结算 去订单页面付款，也可以选择删除购物车里面的商品。

#### 我的订单： ####

可以查看自己的订单的商品，设置5s时间自动关闭。支付使用支付宝沙箱支付，对于已经支付的订单无法二次支付，即使支付也会报错，对于已支付的订单也不能进行取消。

#### 返回数据： ####

支付宝进行回调信息存储到数据库，后台可以接收信息。

![c8290d8636124772ae47f654106fdeb0.png][]进行支付之后，后台可以对订单进行发货，用户在我的订单里面也可以看见订单状态是否发货，从而进行收货操作。

> 完结撒花，对于在线商城这个项目呢，肯定还会有很多的优化，这个项目我也有2个版本，就是服务器上面的和不是服务器上面的，但是基本上都差不多。基本功能呢也都能实现， 只是跟商业的比起来肯定差点意思啦。各位小伙伴觉得笔者写的还不错，就多多点赞，需要源码的也可以私信我哦，看见信息第一时间回复大家。记得点赞关注！！！！
