父模块

在微服务架构中，父模块是指一个聚合多个子模块的模块。父模块通常用于管理整个项目的依赖、插件和构建配置等。父模块的 Maven 配置如下：

<groupId>com.heima</groupId>
<artifactId>hmall</artifactId>
<packaging>pom</packaging>
<version>1.0.0</version>

<modules>
    <module>hm-common</module>
    <module>hm-goods-service</module>
    <module>hm-cart-service</module>
</modules>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.12</version>
    <relativePath/>
</parent>
