IDEA 配置maven结合案例使用篇

1. 项目需求和结构分析

IDEA 配置maven结合案例使用篇_第1张图片

需求案例:搭建一个电商平台项目,该平台包括用户服务、订单服务、通用工具模块等。

项目架构:

  1. 用户服务:负责处理用户相关的逻辑,例如用户信息的管理、用户注册、登录等。
    • spring-context 6.0.6
    • spring-core 6.0.6
    • spring-beans 6.0.6
    • common-service
  2. 订单服务:负责处理订单相关的逻辑,例如订单的创建、订单支付、退货、订单查看等。
    • spring-context 6.0.6
    • spring-core 6.0.6
    • spring-beans 6.0.6
    • spring-security 6.0.6
    • common-service
  3. 通用模块:负责存储其他服务需要通用工具类,其他服务依赖此模块。
    • commons-io 2.11.0
    • junit 5.9.2

2. 项目搭建和统一构建

①父模块 (micro-shop)

可选操作:删除src目录

②通用模块 (common-service)

创建工程:

④订单模块 (order-service)

创建工程,并使用插件转为web工程:

pom.xml配置:


<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>micro-shopartifactId>
        <groupId>com.atguigugroupId>
        <version>1.0-SNAPSHOTversion>
    parent>
    <modelVersion>4.0.0modelVersion>

    <artifactId>order-serviceartifactId>
    
    <packaging>warpackaging>

    <properties>
        <maven.compiler.source>17maven.compiler.source>
        <maven.compiler.target>17maven.compiler.target>
        <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
    properties>

    <dependencies>
        
        <dependency>
            <groupId>com.atguigugroupId>
            <artifactId>common-serviceartifactId>
            <version>1.0-SNAPSHOTversion>
        dependency>
    dependencies>

project>

此时,查看父工程的pom.xml,会发现其中已经自动聚合了子工程:

<modules>
    <module>common-servicemodule>
    <module>user-servicemodule>
    <module>order-servicemodule>
modules>
