springmvc maven idea 多模块开发（三）：建立子模块

传统的多模块方式是建立domain、dao、service等，这种方式是按照软件架构进行分割，现在更多的应该是倾向按照功能来解耦，module前期可以配置成jar，后期也可以建立独有的页面，独立的站点，通过子域名的方式访问，各个功能模块解耦，趋向微服务架构，下面就按照这种方式进行处理

一、建立公共模块

某块生成完毕后，修改本模块的pom.xml，添加必要的包，由于本模块是继承父模块，所以不需要在引用包上加version了

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

二、建立系统管理模块

前几步方法同上 ，

点击后IDEA会生成archetype，但是速度非常慢，如下图所示

解决方法如下：

打开setting，在VM Options内输入 -DarchetypeCatalog=internal，重启idea即可

新模块完成后，在父模块pom.xm中会自动添加模块引用

由于系统管理模块依赖公共模块，所以要在本模块上增加对公共模块的引用

 <?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>xframe</artifactId>
         <groupId>xie.frame</groupId>
         <version>1.0-SNAPSHOT</version>
     </parent>
     <modelVersion>4.0.0</modelVersion>

     <artifactId>xframe-system</artifactId>

     <name>xframe-system</name>
     <packaging>jar</packaging>
     <properties>
         <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
         <maven.compiler.source>1.8</maven.compiler.source>
         <maven.compiler.target>1.8</maven.compiler.target>
     </properties>

     <dependencies>
         <dependency>
             <groupId>junit</groupId>
             <artifactId>junit</artifactId>
         </dependency>
         <dependency>
             <groupId>xie.frame</groupId>
             <artifactId>xframe-common</artifactId>
             <version>${project.version}</version>
         </dependency>
     </dependencies>

 </project>

然后添加系统管理模块的引用包，添加完毕后如下
