章節導航

進行閱讀

1.概述

在多人協同開發時，特别是規模較大的項目，為了友善日後的代碼維護和管理，我們會将每個開發人員的工作細分到具體的功能和子產品上。

随着項目的不斷擴大，子產品也會越來越多，後續會更加難以維護和擴充，為了應對這種情況後期我們還會采用微服務架構的方式進行開發。

本章節以建構一個

IoT雲平台

項目為例，我們可以将子產品劃分為如下形式：

統一的依賴管理（ dependencies ）
通用的工具類（ commons
領域模型（ domain
管理背景（ admin
前端控制台（ console
接口子產品（ api

整個子產品化開發過程主要是在開發思想上稍作了一些轉變，隻需要按照下面的流程操作即可。

2.建立根項目（工程）

建立一個名為

iot-cloud

的工程，

pom.xml

檔案如下：

<?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>net.work100.training.stage2</groupId>
    <artifactId>iot-cloud</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>

    </modules>
</project>

該項目稱之為

Root

項目，主要作用是管理整個工程的全部子產品，當有新子產品加入時需要在

modules

元素下配置對應的子產品目錄

3.建立統一的依賴管理子產品

iot-cloud-dependencies

的項目，

pom.xml

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

檔案：

<?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"

    <artifactId>iot-cloud-web-api</artifactId>
    <packaging>war</packaging>

    <name>iot-cloud-web-api</name>
    <description></description>
</project>

iot-cloud

pom.xml

<module>iot-cloud-web-api</module>

9.清理、編譯、打包

至此一個完整的子產品化工程建立完畢，此時的

Root

工程

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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>net.work100.training.stage2</groupId>
    <artifactId>iot-cloud</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>
        <module>iot-cloud-dependencies</module>
        <module>iot-cloud-commons</module>
        <module>iot-cloud-domain</module>
        <module>iot-cloud-web-admin</module>
        <module>iot-cloud-web-console</module>
        <module>iot-cloud-web-api</module>
    </modules>
</project>

我們可以在

Root

工程中使用

Maven

提供的

mvn clean

指令測試一下效果，控制台輸出如下：
