使用Maven创建父项目

<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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.fan</groupId>
    <artifactId>springboot-template</artifactId>
    <version>1.0.0</version>
    <packaging>pom</packaging>

    <name>springboot-template</name>
    <url>https://xxx.com</url>
    <description>项目模块</description>

    <modules>
        <module>pro-main</module>
        <module>pro-entity</module>
    </modules>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>17</java.version>
        <mybatisplus.version>3.5.10.1</mybatisplus.version>
    </properties>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.4.2</version>
        <relativePath/>
    </parent>

    <dependencies>

    </dependencies>
</project>

同理创建子工程

<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">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.fan</groupId>
        <artifactId>springboot-template</artifactId>
        <version>1.0.0</version>
    </parent>

    <artifactId>pro-main</artifactId>
    <packaging>jar</packaging>

    <name>pro-main</name>
