springboot聚合工程是什么意思

发布时间:2021-11-03 15:09:08 来源:亿速云 阅读:135 作者:小新 栏目:开发技术

小编给大家分享一下springboot聚合工程是什么意思,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!

    1.什么是聚合工程

    如下图所示,拥有父子包结构的springboot工程叫做聚合工程。其中父包包括了多个子包(多个项目)。

    2.聚合工程优势

    1. 组件化管理通用功能,动态的添加功能。

    2. 统一管理jar包的版本号

    3. 提高复用性

    3.创建聚合工程

    1.首先创建一个springboot项目,然后删除src文件夹 。

    2.创建子工程

    springboot聚合工程是什么意思

    选择spring boot项目,然后继续,创建项目。如果是工具,配置,组件化的项目(不需要启动)可以继续删除启动类和resources文件夹。

    3. 修改父工程和子工程pom文件。然后聚合工程就搭建好了,这里最重点是pom文件的配置和标签,下文就开始介绍。

    4.父工程详解

    ps:这里以若依开源项目为例,结构如下,我们主要讲解红框里面的配置,父工程为RuoYi-Cloud,包括ruoyi-auth,ruoyi-gateway,ruoyi-visual,ruoyi-api,ruoyi-common子项目。而ruoyi-modules子工程也包括多个子工程。

    <name><url><description>都是非必须,字面意思。
    <groupId>:域 例如com
    <artifactId>:公司名  groupid和artifactId被统称为“坐标”是为了保证项目唯一性而提出的
    <version>:项目的版本号
    <properties>:属性的占位符 如java中的常量 
    
    <dependencyManagement>:在我们项目顶层的POM文件中,我们会看到dependencyManagement元素。通过它元素来管理jar包的版本,让子项目中引用一个依赖而不用显示的列出版本号。Maven会沿着父子层次向上走,直到找到一个拥有dependencyManagement元素的项目,然后它就会使用在这个dependencyManagement元素中指定的版本号。
    
    <dependencies>:指定所有的子工程都下载该包。

    白话说 如果父工程有,且groupId和artifactId相同,那么子工程不需要指定版本号, 直接使用父工程版本号。

    例如:当子工程有groupId为org.springframework.cloud时,引用当前父工程指定版本。子工程不用在写版本号了。

    <!-- SpringCloud 微服务 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>${spring-cloud.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>

    <modules>:指当前父工程包含的子工程 如果这里不引入 那么 刷新父工程pom时 子工程不会下载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时 直接引入代码,否则就会打成jar包 这样就会报错了

    5.ruoyi-modules子工程配置

    这里我们选择一个最有代表性的子工程ruoyi-modules来介绍。

    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"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <parent>
            <groupId>com.ruoyi</groupId>
            <artifactId>ruoyi</artifactId>
            <version>2.5.0</version>
        </parent>
        <modelVersion>4.0.0</modelVersion>
    
        <modules>
            <module>ruoyi-system</module>
            <module>ruoyi-gen</module>
            <module>ruoyi-job</module>
            <module>ruoyi-file</module>
        </modules>
    
        <artifactId>ruoyi-modules</artifactId>
        <packaging>pom</packaging>
    
        <description>
            ruoyi-modules业务模块
        </description>
    
    </project>

    这里主要配置是

    <parent>:内容就是父工程的<groupId><artifactId><version>
    <modules>:指该工程包含ruoyi-system,ruoyi-gen,ruoyi-job,ruoyi-file子工程

    2.ruoyi-system子项目配置

    <?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"

    <parent>:配置父工程ruoyi-modules的<groupId><artifactId><version>
    <dependencies>:本项目的依赖

    如果想引入其他工程,只需要加入:
