高效构建Java应用：Maven入门和进阶（五）

Maven实战案例：搭建微服务Maven工程框架

5.1 项目需求和结构分析

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。
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。
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。

服务依赖：

1. 用户服务 (1.0.1)
   • spring-context 6.0.6
   • spring-core 6.0.6
   • spring-beans 6.0.6
   • jackson-databind / jackson-core / jackson-annotations 2.15.0
2. 订单服务 (1.0.1)
   1. shiro-core 1.10.1
   2. spring-context 6.0.6
   3. spring-core 6.0.6
   4. spring-beans 6.0.6
3. 通用模块 (1.0.1)
   1. commons-io 2.11.0

5.2项目搭建和统一构建

1. 父模块搭建 (micro-shop)

   • 创建父工程

   • pom.xml配置

<?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.atguigu</groupId><artifactId>micro-shop</artifactId><version>1.0.1</version><!-- 父工程不打包，所以选择pom值--><packaging>pom</packaging><properties><spring.version>6.0.6</spring.version><jackson.version>2.15.0</jackson.version><shiro.version>1.10.1</shiro.version><commons.version>2.11.0</commons.version><maven.compiler.source>17</maven.compiler.source><maven.compiler.target>17</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><!-- 依赖管理 --><dependencyManagement><dependencies><!-- spring-context会依赖传递core/beans --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><!-- jackson-databind会依赖传递core/annotations --><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>${jackson.version}</version></dependency><!-- shiro-core --><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-core</artifactId><version>${shiro.version}</version></dependency><!-- commons-io --><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>${commons.version}</version></dependency></dependencies></dependencyManagement><dependencies><!-- 父工程添加依赖，会自动传递给所有子工程，不推荐！ --></dependencies><!-- 统一更新子工程打包插件--><build><!-- jdk17 和 war包版本插件不匹配 --><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-war-plugin</artifactId><version>3.2.2</version></plugin></plugins></build></project>

2. 通用模块 (common-service)

   • 创建模块

     

   • pom.xml配置

<?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><parent><groupId>com.atguigu</groupId><artifactId>micro-shop</artifactId><version>1.0.1</version></parent><artifactId>common-service</artifactId><!-- 打包方式默认就是jar！ --><packaging>jar</packaging><properties><maven.compiler.source>17</maven.compiler.source><maven.compiler.target>17</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><!-- 声明commons-io，继承父工程版本 --><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId></dependency></dependencies></project>

3. 用户模块 (user-service)

   • 创建模块
     
     

   • pom.xml配置

<?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>  <parent> <groupId>com.atguigu</groupId>  <artifactId>micro-shop</artifactId>  <version>1.0.1</version> </parent>  <artifactId>user-service</artifactId>  <packaging>war</packaging><properties> <maven.compiler.source>17</maven.compiler.source>  <maven.compiler.target>17</maven.compiler.target>  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties><dependencies><!-- 添加spring-context 自动传递 core / beans --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></dependency><!-- 添加jackson-databind 自动传递 core / annotations --><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId></dependency></dependencies>
</project>

4. 订单模块 (order-service)
   • 创建模块

• 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><parent><groupId>com.atguigu</groupId><artifactId>micro-shop</artifactId><version>1.0.1</version></parent><artifactId>order-service</artifactId><packaging>war</packaging><properties><maven.compiler.source>17</maven.compiler.source><maven.compiler.target>17</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><!-- 继承父工程依赖版本 --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></dependency><!-- 继承父工程依赖版本 --><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-core</artifactId></dependency></dependencies></project>
