專案大體結構如下

專案

    spring boot專案通用模組 SpringBase 

    專案基礎模組 ProjectCommon

    各個任務邏輯模組 A B C ...

上文建立專案中 刪除除了pom.xml以外所有檔案 並更新pom.xml

	<groupId>com.mycompany</groupId>
	<artifactId>MyProject</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>pom</packaging>


	<name>MyProject</name>
	<description>Starter project for MyProject</description>


	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.2.BUILD-SNAPSHOT</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	
	
	<modules>
		<module>SpringBootCommon</module>
		<module>MyProjectCommon</module>
		<module>MyProjectModuleA</module>
	</modules>
	
	  <!--指定專案中公有的模組-->
	<dependencyManagement>
	  <dependencies>
	    <dependency>
	      <groupId>com.mycompany</groupId>
	      <artifactId>SpringBootCommon</artifactId>
	      <version>0.0.1-SNAPSHOT</version>
	    </dependency>
	    <dependency>
	      <groupId>com.mycompany</groupId>
	      <artifactId>MyProjectCommon</artifactId>
	      <version>0.0.1-SNAPSHOT</version>
	    </dependency>
	  </dependencies>
	</dependencyManagement>


	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>
 

MyProject 專案右鍵 maven new maven module project

依次建立3個子模組

<module>SpringBootCommon</module>
<module>MyProjectCommon</module>
<module>MyProjectModuleA</module>

SpringBootCommon pom 如下

  <parent>
    <groupId>com.mycompany</groupId>
    <artifactId>MyProject</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <relativePath>../pom.xml</relativePath>
  </parent>
  <artifactId>SpringBootCommon</artifactId>
  <name>SpringBootCommon</name>
  <description>Spring Boot Starter</description>
 

MyProjectCommon pom 如下

  <parent>
    <groupId>com.mycompany</groupId>
    <artifactId>MyProject</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <relativePath>../pom.xml</relativePath>
  </parent>
  <artifactId>MyProjectCommon</artifactId>
  <name>MyProjectCommon</name>
  <description>My project Common</description>
 

MyProjectModuleA pom 如下

<parent>
    <groupId>com.mycompany</groupId>
    <artifactId>MyProject</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <relativePath>../pom.xml</relativePath>
  </parent>
  <artifactId>MyProjectModuleA</artifactId>
  <name>MyProjectModuleA</name>
  <packaging>jar</packaging>
  
  <dependencies>
    <dependency>
      <groupId>com.mycompany</groupId>
      <artifactId>SpringBootCommon</artifactId>
    </dependency>
    <dependency>
      <groupId>com.mycompany</groupId>
      <artifactId>MyProjectCommon</artifactId>
    </dependency>
  </dependencies>

	<!--spring boot打包的話需要指定一個唯一的入門-->
	<build>
		<plugins>
			<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
			<version>1.4.2.RELEASE</version>
			<configuration>
	            <!-- 指定該Main Class為全域性的唯一入口 -->
	            <mainClass>com.mycompany.StartApplication</mainClass>
	            <layout>ZIP</layout>
          	</configuration>
			<executions>
				<execution>
					<goals>
						<goal>repackage</goal><!--可以把依賴的包都打包到生成的Jar包中-->
					</goals>
				</execution>
			</executions>
			</plugin>
		</plugins>
	 </build>

最後對專案外殼進行mvn package即可生成各模組jar

注意 專案外殼不要寫maven build內容

哪個模組需要打包哪個模組寫maven build外掛
