bom子模块依赖关系冲突

JoeyBling commented 1 year ago

bom子模块依赖了父模块mybatis-parent，父模块也声明了其它依赖管理dependencyManagement，则会覆盖spring-boot项目parent的声明，导致spring-boot-dependencies声明失效，

在里面有声明spring-framework-bom，会导致Spring框架工件版本和spring-boot管理的版本不一致

引入spring-boot

<parent>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.4</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

依赖管理引入bom模块

<!-- 依赖管理 -->
<dependencyManagement>
<dependency>
<groupId>io.mybatis</groupId>
<artifactId>mapper-bom</artifactId>
<version>2.0.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencyManagement>

建议2种方式处理

bom子模块还是按照最开始的样子单独管理，不依赖于parent
父模块mybatis-parent去除依赖管理dependencyManagement

BOM模块应该仅仅只有是该组件包各个子模块的依赖声明，不应出现其它依赖管理

bom添加下面的配置:

<build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>flatten-maven-plugin</artifactId>
        <version>1.1.0</version>
        <configuration>
          <updatePomFile>true</updatePomFile>
          <flattenMode>bom</flattenMode>
        </configuration>
        <executions>
          <execution>
            <id>flatten</id>
            <phase>process-resources</phase>
            <goals>
              <goal>flatten</goal>
            </goals>
          </execution>
          <execution>
            <id>flatten.clean</id>
            <phase>clean</phase>
            <goals>
              <goal>clean</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

重点是 <flattenMode>bom</flattenMode>，生成的 pom 如下：
