## 一、创建父模块 ##

File --> New --> Project ，选择 “ Spring Initalizr ” ，点击 Next

Next --> Finish

## 二、创建子模块 ##

右键根目录，New --> Module

![05d7220e38434342bfa7f8fb788f7750.png][]选择 “ Spring Initializr ”，点击Next

此处注意Type选择Maven，Artifact根据自己的分模块的标准进行命名，可以按功能分模块（比如：订单、支付、登陆等模块分，就可以命名为order、pay、login等），此处我按照公共模块，业务模块、工具模块等模块进行划分的。

Next --> Finish

重复上述步骤，根据自身需要再创建其他子模块

## 三、修改pom文件 ##

子模块

<?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">

        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.7.5</version>
            <relativePath/> 
        </parent>
    
        <groupId>com.hng</groupId>

        <version>0.0.1-SNAPSHOT</version>
        <name>business</name>
        <description>业务模块</description>
        <properties>
            <java.version>8</java.version>
        </properties>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>

            </dependency>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    
    </project>

父模块

<?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>
        <groupId>com.hng</groupId>
        <artifactId>server</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <name>server</name>
        <description>父模块</description>
        <packaging>pom</packaging>
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.7.5</version>
            <relativePath/> 
        </parent>
    
        <properties>
            <java.version>8</java.version>
        </properties>
    
        
        <modules>
            <module>common</module>
            <module>business</module>
            <module>system</module>
            <module>tools</module>
        </modules>
    
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
    
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    
    </project>

四、删除多余不必要的文件及目录

1.删除所有子模块的 **mvnw**、**mvnw.cmd、xxx.iml** 文件及 **.mvn** 文件夹

![058c01819c704d10a4bba818a0149acf.png][]

2.删除所有子模块resources文件夹

![82e7aebe08c8468091ed322a1967e114.png][]

3.删除所有子模块的的启动类

![81538705cad94b1287771bc028a2d59b.png][]

五、在主模块中添加测试代码，启动项目测试

在主模块business中创建对应的包controller、service等，在controller创建测试代码

package com.hng.business.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @Author 郝南过
     * @Date 2023/11/3 12:21
     * @Version 1.0
     */
    @RestController
    public class TestController {
    
        @RequestMapping("/test")
        public String hello(){
            return "Hello";
        }
    }

使用主模块business的启动文件启动项目，访问localhost:8080/test，可以正常看到响应（默认端口为8080，如需要修改可在主模块business下的resources下的application.properties文件中进行配置修改）
