idea新建聚合项目并附上标签的详细过程

首先新建父工程

新建spring boot项目

填写项目信息

指定该子项目的路径

如果是组件类型的子项目 可以删除application.xml和启动类

父工程pom文件

1. <?xml version="1.0" encoding="UTF-8"?> 
2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
3.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

11.     </properties> 
12.   
13.     <modules> 
14.         <module>common-mail</module> 
15.     </modules> 
16.   
17.     <packaging>pom</packaging> 
18.   
19.     <dependencyManagement> 
20.         <dependencies>    
21.             <dependency>

25.             </dependency> 
26.         </dependencies> 
27.     </dependencyManagement> 
28.   
29.     <dependencies> 
30.         <!-- swagger --> 
31.         <dependency> 
32.             <groupId>io.swagger</groupId> 
33.             <artifactId>swagger-annotations</artifactId> 
34.             <version>1.5.10</version> 
35.         </dependency> 
36.     </dependencies> 
37.   
38.     <build>

45.                     <target>${java.version}</target> 
46.                     <encoding>${project.build.sourceEncoding}</encoding> 
47.                 </configuration> 
48.             </plugin> 
49.         </plugins> 
50.     </build> 
51.   
52. </project> 

<modules>:为包含的子工程artifactId名
<properties>：指常量 一般为版本号 方便统一修改
<dependencyManagement>：指定子工程有相同jar包时，使用父工程的版本号，而子工程不用在额外指定
<dependencies>:为父子工程可以同时引入的jar包

子工程pom文件

1. <?xml version="1.0" encoding="UTF-8"?>

 <parent>：为父工程的信息 也就是父工程pom中的groupId，artifactId 必填  <build>：为打包时的配置

注意com.vanpeng.assembly.BusinessApplication一定要配置 否则jar包启动会找不到主函数 pom也必须配置 这是在父子工程中必须配置的 意思是 需要以方式引入 而不是打成jar
