Maven实战—搭建微服务 Maven 工程架构

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：

1. 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。
2. 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。
3. 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：

1. 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
2. 订单服务 (1.0.1)
   1. shiro-core 1.10.1
   2. spring-context 6.0.6
   3. spring-core 6.0.6
   4. spring-beans 6.0.6
3. 通用模块 (1.0.1)
   1. commons-io 2.11.0

1 创建父工程 maven-micro-shop

2 创建通用模块 common-service

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

使用maven中的构建命令install，将这个项目放到maven本地仓库，以供其他两个模块（user-service 和 order-service）使用。

显示出BUILD SUCCESS表示构建成功。

3 创建用户模块 user-service

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4 创建订单模块 order-service

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
