需求：公司要求做的项目必须用多模块进行管理，于是就有了这一篇文章。 具体做法：首先需要明确你的项目需要拆分为几个模块。这里提一个小建议，抽出一个模块专门用来管理jar。接下来直接亮出我这边是怎么做的

<?xml version="1.0" encoding="UTF-8"?>
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>2.6.4</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.ss</groupId>
    <artifactId>a</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    <modules>
        <module>a-job</module>
        <module>a-business</module>
        <module>a-parent</module>
    </modules>
</project>

通过上面pom.xml发现一共分三个模块，其中a-parent模块专门用来管理jar 接下来看看a-parent这个模块的pom.xml

<?xml version="1.0" encoding="UTF-8"?>

        <groupId>com.ss</groupId>

    </parent>

    <artifactId>a-parent</artifactId>
