使用 SpringBoot 和 React 子模块设置多模块 Maven 项目

问题描述 投票：0回答：2

我正在尝试设置一个包含 SpringBoot 和 React 应用程序的 monorepo。目前，我的模块结构如下所示：

root
+-- backend
|   +-- pom.xml
+-- frontend
|   +-- pom.xml
+-- pom.xml

家长pom：

<?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>org.example</groupId>
    <artifactId>multi-module-demo</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>
        <module>frontend</module>
        <module>backend</module>
    </modules>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

</project>

前端/pom：

<?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>org.example</groupId>
        <artifactId>multi-module-demo</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <artifactId>frontend</artifactId>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

</project>

和后端/pom：

<?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>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.0.2</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

    <artifactId>backend</artifactId>

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

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

在查看

backend/pom.xml
时，我遇到一个问题，父级不是我的父级pom，而是SpringBoot pom。然而，这样一来，我在技术上就无法管理，例如项目的版本。因为当前构建输出是

[INFO] Reactor Summary:
[INFO] 
[INFO] multi-module-demo 1.0-SNAPSHOT ..................... SUCCESS [  0.150 s]
[INFO] frontend 1.0-SNAPSHOT .............................. SUCCESS [  0.784 s]
[INFO] backend 3.0.2 ...................................... SUCCESS [  4.102 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS

您可以在其中看到每个工件的版本不匹配。

我的问题是，我需要如何调整后端 pom 以匹配前端 pom？

spring-boot maven monorepo multi-module

经过进一步挖掘，这是我需要添加到我的父 pom 中的内容：

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-parent</artifactId>
                <version>3.0.2</version>
                <scope>import</scope>
                <type>pom</type>
            </dependency>
        </dependencies>
    </dependencyManagement>

我有一个与你类似的问题，相同的pom结构，使用ant将Java ee项目迁移到springboot java多模块。

pom的原理是这样的：

错误是在war包中没有检测到ejb的注入导入类。
