用maven生成springboot多模块项目

用Maven生成Spring Boot多模块项目，可以按照以下步骤操作：

1. 创建父项目

首先，使用Maven的archetype插件创建一个空的Maven项目作为父项目。打开终端，执行以下命令：

mvn archetype:generate -DgroupId=com.example -DartifactId=springboot-multi-module-demo -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

这将创建一个名为springboot-multi-module-demo的项目，其groupId为com.example。

2. 进入父项目根目录

cd springboot-multi-module-demo

3. 删除父项目中的src目录

# Linux
rm -rf src# OR Window
rmdir /S /Q src

4. 配置父项目的`pom.xml`

进入父项目目录，打开pom.xml文件，将其配置为Spring Boot父项目，并设置打包方式为pom。以下是一个示例pom.xml：

<?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/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.example</groupId><artifactId>springboot-multi-module-demo</artifactId><packaging>pom</packaging><version>1.0-SNAPSHOT</version><name>springboot-multi-module-demo</name><url>http://maven.apache.org</url><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.4.3</version><relativePath/><!-- lookup parent from repository --></parent><properties><java.version>21</java.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencyManagement><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>3.4.3</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement></project>

5. 创建子模块

在父项目目录下，使用Maven命令创建子模块。以下是创建三个子模块的示例：

mvn archetype:generate -DgroupId=com.example -DartifactId=module-api -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
mvn archetype:generate -DgroupId=com.example -DartifactId=module-service -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
mvn archetype:generate -DgroupId=com.example -DartifactId=module-web -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

6. 配置子模块的`pom.xml`

每个子模块的pom.xml需要继承父项目，并根据需要添加依赖。以下是每个子模块的pom.xml示例：

（1）module-api

<?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"><modelVersion>4.0.0</modelVersion><parent><groupId>com.example</groupId><artifactId>springboot-multi-module-demo</artifactId><version>1.0-SNAPSHOT</version></parent><artifactId>module-api</artifactId><dependencies><!-- 这里添加API模块所需的依赖 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>test</scope></dependency></dependencies></project>

（2）module-service

<?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"><modelVersion>4.0.0</modelVersion><parent><groupId>com.example</groupId><artifactId>springboot-multi-module-demo</artifactId><version>1.0-SNAPSHOT</version></parent><artifactId>module-service</artifactId><dependencies><dependency><groupId>com.example</groupId><artifactId>module-api</artifactId><version>${project.version}</version></dependency><!-- 这里添加Service模块所需的依赖 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>test</scope></dependency></dependencies></project>

（3）`module-web`

<?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"><modelVersion>4.0.0</modelVersion><parent><groupId>com.example</groupId><artifactId>springboot-multi-module-demo</artifactId><version>1.0-SNAPSHOT</version></parent><artifactId>module-web</artifactId><dependencies><dependency><groupId>com.example</groupId><artifactId>module-service</artifactId><version>${project.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!-- 这里添加Web模块所需的依赖 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>
