项目结构规划
假设我们这个项目有客户模块与管理员模块. 则项目结构划分为如上图:

新建父模块

配置pom.xml

修改前:

<?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">

    <groupId>com.maoyupeng.test</groupId>

修改后

    <!--
        子模块引入
    -->
    <modules>

    </modules>

    <!--
        定义属性变量
        使用方法例如: <version>${mpicloid.version}</version>
        这样version里面的值为0.0.1-SNAPSHOT
    -->
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

        <!--客户端提供方jar版本-->
        <mpi-client-provide.version>0.0.1-SNAPSHOT</mpi-client-provide.version>
    </properties>

    <!--引入spring boot 核心包-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <!--引入依赖包-->
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>

    </dependencies>

    <!--插件-->
    <build>

            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

    <!--指定spring镜像仓库,有的时候依赖包会报错,如果引入了该仓库,就会解决问题-->
    <repositories>
        <repository>
            <id>spring-snapshots</id>
            <name>Spring Snapshots</name>
            <url>https://repo.spring.io/snapshot</url>
            <snapshots>

            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

</project>

新建子模块

步骤截图

修改子模块(mpi-client-service)的pom.xml

修改前

<?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>mpicloud</artifactId>
        <groupId>com.maoyupeng.test</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>mpi-client-service</artifactId>


</project>

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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>mpicloud</artifactId>
        <groupId>com.maoyupeng.test</groupId>
        <!--修改: 引用父模块中的properties, 引入成功,则配置生效-->
        <version>${mpicloid.version}</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>mpi-client-service</artifactId>

</project>

验证

由上图可知,在mpi-client-service(pom.xml)里面没有引入任何的依赖包,但是在Maven Dependencies 里面,则显示出了与父模块一样的引用依赖.

最后的项目结构

其他子模块的新建步骤雷同,所以省略...
