父子工程搭建
1. 构建父工程
父工程的职责是对依赖包的版本进行管理，创建父工程分两步，第一创建父工程，第二在pom.xml编辑依赖管理。
进入新建模块界面，选择Spring Initializr，填写模块的信息：
创建成功，删除多余文件：
2、依赖管理定义
父工程中没有代码，不用去依赖其它的包，它的作用是限定其它子工程依赖包的版本号，即在dependencyManagement中去编辑即可。
1）确定父工程为一个pom工程，在pom.xml中添加如下内容：
<packaging>pompackaging>
2）编辑依赖的包的版本号、打包插件等。
pom.xml如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2. 构建子工程
1、首先在项目根目录创建内容管理模块的父工程xuecheng-plus-content：
创建完成，只保留pom.xml文件，删除多余的文件。
内容管理父工程的主要职责是聚合内容管理接口和内容管理接口实现两个工程，它的父工程是xuecheng-plus-parent。
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd">

2、在其下创建model数据模型工程。
创建完成，只保留包和pom.xml文件，删除多余的文件。
<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 https://maven.apache.org/xsd/maven-4.0.0.xsd">

3、在其下创建service接口实现工程。
创建完成，只保留包和pom.xml文件 ，删除多余的文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4、在其下创建api接口工程。
xuecheng-plus-content-api接口工程的父工程是xuecheng-plus-content，它依赖了xuecheng-plus-base基础工程。
