SpringCloud alibaba微服务b2b2c电子商务平台

**SpringCloud Alibaba微服务B2C电子商务平台**

在本文中，我们将介绍如何使用SpringCloud Alibaba构建一个B2C电子商务平台。该平台将包含多个微服务，包括用户服务、商品服务、订单服务等。

###1.项目结构首先，我们需要定义项目的结构。我们将创建以下模块：

* `b2c-common`:公共依赖包* `b2c-user-service`:用户服务* `b2c-goods-service`:商品服务* `b2c-order-service`:订单服务* `b2c-payment-service`:支付服务###2.依赖管理在每个模块中，我们需要定义对应的pom.xml文件，指定所需的依赖。
