1.什么是聚合工程
如下圖所示，擁有父子包結(jié)構(gòu)的springboot工程叫做聚合工程。其中父包包括了多個(gè)子包（多個(gè)項(xiàng)目）。
2.聚合工程優(yōu)勢(shì)
- 組件化管理通用功能，動(dòng)態(tài)的添加功能。
- 統(tǒng)一管理jar包的版本號(hào)
- 提高復(fù)用性
3.創(chuàng)建聚合工程
1.首先創(chuàng)建一個(gè)springboot項(xiàng)目，然后刪除src文件夾 。
2.創(chuàng)建子工程
選擇spring boot項(xiàng)目，然后繼續(xù)，創(chuàng)建項(xiàng)目。如果是工具，配置，組件化的項(xiàng)目（不需要啟動(dòng)）可以繼續(xù)刪除啟動(dòng)類和resources文件夾。
3. 修改父工程和子工程pom文件。然后聚合工程就搭建好了，這里最重點(diǎn)是pom文件的配置和標(biāo)簽，下文就開始介紹。
4.父工程詳解
ps:這里以若依開源項(xiàng)目為例，結(jié)構(gòu)如下，我們主要講解紅框里面的配置，父工程為RuoYi-Cloud，包括ruoyi-auth，ruoyi-gateway，ruoyi-visual，ruoyi-api，ruoyi-common子項(xiàng)目。而ruoyi-modules子工程也包括多個(gè)子工程。

<name><url><description>都是非必須，字面意思。 <groupId>：域 例如com <artifactId>：公司名 groupid和artifactId被統(tǒng)稱為“坐標(biāo)”是為了保證項(xiàng)目唯一性而提出的 <version>：項(xiàng)目的版本號(hào) <properties>：屬性的占位符 如java中的常量 <dependencyManagement>：在我們項(xiàng)目頂層的POM文件中，我們會(huì)看到dependencyManagement元素。通過它元素來管理jar包的版本，讓子項(xiàng)目中引用一個(gè)依賴而不用顯示的列出版本號(hào)。Maven會(huì)沿著父子層次向上走，直到找到一個(gè)擁有dependencyManagement元素的項(xiàng)目，然后它就會(huì)使用在這個(gè)dependencyManagement元素中指定的版本號(hào)。 <dependencies>：指定所有的子工程都下載該包。
白話說 如果父工程有，且groupId和artifactId相同，那么子工程不需要指定版本號(hào)， 直接使用父工程版本號(hào)。
例如：當(dāng)子工程有g(shù)roupId為org.springframework.cloud時(shí)，引用當(dāng)前父工程指定版本。子工程不用在寫版本號(hào)了。

<modules>：指當(dāng)前父工程包含的子工程 如果這里不引入 那么 刷新父工程pom時(shí) 子工程不會(huì)下載jar包
<build>：打包配置
<packaging>pom</packaging>在聚合工程中 一定要配置 指的是在引入其他工程時(shí) 直接引入代碼，否則就會(huì)打成jar包 這樣就會(huì)報(bào)錯(cuò)了
5.ruoyi-modules子工程配置
這里我們選擇一個(gè)最有代表性的子工程ruoyi-modules來介紹。
1.pom文件
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0"

</modules>
<artifactId>ruoyi-modules</artifactId>
<packaging>pom</packaging>
<description>
ruoyi-modules業(yè)務(wù)模塊
</description>
</project>
這里主要配置是
<parent>：內(nèi)容就是父工程的<groupId><artifactId><version>
<modules>：指該工程包含ruoyi-system，ruoyi-gen，ruoyi-job，ruoyi-file子工程
2.ruoyi-system子項(xiàng)目配置
