我正在尝试使用spring和maven创建一个父子项目,但运气不好。我发现了很多例子,但都涉及到多模块项目。
我有一个核心项目,需要导入到其他许多子项目。核心项目有一些依赖项,这些依赖项必须继承给子项目。
我试图将核心项目转换为多模块,但没有成功。这是我的配置。
核心项目pom.xml(它有一个模块)

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>it.mygroup</groupId>
    <artifactId>core-be</artifactId>
    <version>1.0.0</version>
    <name>core-be</name>
    <packaging>pom</packaging>

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

</project>

接下来是定义spring引导配置等的模块后端。

<?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 https://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>2.4.0</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>it.mygroup</groupId>
    <artifactId>backend</artifactId>
    <version>1.0.0</version>
    <name>backend</name>

    <properties>
        <java.version>1.8</java.version>
    </properties>

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

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

这是需要导入到任何其他项目中的核心项目。我尝试将其作为父级导入,但找不到核心项目中定义的所有类:

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>it.mygroup</groupId>
        <artifactId>core-be</artifactId>
        <version>1.0.0</version>
    </parent>
    <groupId>it.mygroup</groupId>
    <artifactId>my-project</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <name>my-project</name>

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

</project>

对于作为父级的核心项目配置:

<?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 https://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>2.4.0</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>it.mygroup</groupId>
    <artifactId>core-be</artifactId>
    <version>1.0.0</version>
    <name>core-be</name>
    <packaging>pom</packaging>

    <modules>
        <module>backend</module>
        <module>my-project</module>
    </modules>

    <properties>
        <java.version>1.8</java.version>
    </properties>

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

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

</project>

之后,每个项目将从中继承:

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>it.mygroup</groupId>
        <artifactId>core-be</artifactId>
        <version>1.0.0</version>
    </parent>

    <groupId>it.mygroup</groupId>
    <artifactId>backend</artifactId>
    <version>1.0.0</version>
    <name>backend</name>

</project>

以及我的项目配置:

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>it.mygroup</groupId>
        <artifactId>core-be</artifactId>
        <version>1.0.0</version>
    </parent>

    <groupId>it.mygroup</groupId>
    <artifactId>my-project</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <name>my-project</name>

</project>
