创建父项目 mall

先创建一个"父项目"mall,再在这个父项目中创建多个子项目

  • 修改pom文件

最终mall的pom文件如下

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.4</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.taobao</groupId>
    <artifactId>mall</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>mall</name>
    <description>Demo project for Spring Boot</description>
    <!--   当前项目会以一个pom文件的形式被子项目继承   -->
    <packaging>pom</packaging>
</project>

创建子项目

创建mall-stock项目

在父项目的pom文件中,编写子项目的存在

<!--  表示当前项目是一个父项目,以pom文件的形式,供子项目继承  -->
<packaging>pom</packaging>
<!--  当前父项目包含的所有模块  -->
<modules>
    <module>mall-stock</module>
</modules>

子项目pom文件修改后

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.taobao</groupId>
        <artifactId>mall</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.taobao</groupId>
    <artifactId>mall-stock</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>mall-stock</name>
    <description>Demo project for Spring Boot</description>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
    </dependencies>
</project>

父子相认完成

这样当前子项目就可以读取父项目中的pom文件信息了

父项目管理依赖版本

这样做可以统一所有子项目的版本,在更新版本时,只需要修改父项目中定义的版本号即可

父项目的pom文件添加如下内容

<!--  定义父项目需要的版本号参数   -->
<properties>
    <mybatis.version>2.2.2</mybatis.version>
</properties>
<!--   dependencyManagement不是添加依赖,而是确定子项目使用依赖时的版本,也称锁版本  -->
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>${mybatis.version}</version>
        </dependency>
    </dependencies>
</dependencyManagement>

子项目中如果需要mybatis的依赖只需要添加如下内容即可,无需再指定版本号

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
</dependency>

父项目完整pom文件如下
