Maven实战案例:搭建微服务Maven工程框架
5.1 项目需求和结构分析
需求案例:搭建一个电商平台项目,该平台包括用户服务、订单服务、通用工具模块等。
项目架构:
- 用户服务:负责处理用户相关的逻辑,例如用户信息的管理、用户注册、登录等。
- 订单服务:负责处理订单相关的逻辑,例如订单的创建、订单支付、退货、订单查看等。
- 通用模块:负责存储其他服务需要通用工具类,其他服务依赖此模块。
服务依赖:
- 用户服务 (1.0.1)
- spring-context 6.0.6
- spring-core 6.0.6
- spring-beans 6.0.6
- jackson-databind / jackson-core / jackson-annotations 2.15.0
- 订单服务 (1.0.1)
- shiro-core 1.10.1
- spring-context 6.0.6
- spring-core 6.0.6
- spring-beans 6.0.6
- 通用模块 (1.0.1)
- commons-io 2.11.0
5.2项目搭建和统一构建
- 父模块搭建 (micro-shop)
-
创建父工程
-
pom.xml配置
