13 maven Modular Development

Others 2019-06-17 12:17:12 views: null

Outline

In multiplayer collaborative development, especially large-scale projects, in order to facilitate future code maintenance and management, we will work each developer down to the specific functions and modules. With the continuous expansion of the project, the module will be more and more, follow-up will be more difficult to maintain and extend, in order to deal with this later period we will adopt micro-architecture approach to service development.

The current tutorial example, we can module is divided into the following forms:

  • Unified dependency management (dependencies)
  • Generic tools (commons)
  • Domain model (domain)
  • Management background (admin)
  • Shop front end (UI)
  • Interface module (API)

Modular entire development process mainly in developing some thought a little change, you only need to operate according to the following procedure.

Create a root project (project)

Create a file called  my-shop project, pom.xml the following documents:

<?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>

    <groupId>com.funtl</groupId>
    <artifactId>my-shop</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    
    <modules>
    
    </modules>
</project>

The project is called Root project, the main role is to manage the whole project all of the modules, it is necessary when a new module is added to  modules the configuration module corresponding directory element

Create a unified dependency management

Create a file called  my-shop-dependencies project pom.xml file as follows:

<?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>

    </dependencies>

</project>

PS: Do not forget to  my-shop project  pom.xml an increase in  <module>my-shop-web-api</module> the configuration

Clean up, compile, package

At this point a complete modular project is created, then the Root project  pom.xml file as follows:

<?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>

    <groupId>com.funtl</groupId>
    <artifactId>my-shop</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>
        <module>my-shop-dependencies</module>
        <module>my-shop-commons</module>
        <module>my-shop-domain</module>
        <module>my-shop-web-admin</module>
        <module>my-shop-web-ui</module>
        <module>my-shop-web-api</module>
    </modules>
</project>

We can use Maven provided Root engineering  mvn clean command to test the effect, the console output is as follows:
