Maven工具，以及maven项目的创建将不做科普。学者自学；

**1.最外层的项目pom.xml（jar包应用不在赘述）：项目名称：peit**

一个<artifactId>peit</artifactId>项目中包含了一个<module>appapi</module>项目

注意：appapi项目pom.xml中包含了两个项目：

<module>garageApi</module>

<module>lgbirdapi</module>

**2.第二层的POM.xml配置:项目名称：appapi**

**3.第三层POM.xml配置：项目名称garageApi**

**优点：**

1.引用jar包方便，可以直接在父项目中应用，全体项目均可享用；同时子项目和独立

2.打war包方便，可以在第一层项目中打出所有的项目包；

3.最大的有点，其实是拓展简单方便；让一个大的项目，分为若干子项目。子项目再选中是否有必要进一步拆分。
