<!--    <dependency>-->
<!--      <groupId>org.springframework.boot</groupId>-->
<!--      <artifactId>spring-boot-configuration-processor</artifactId>-->
<!--      <optional>true</optional>-->
<!--    </dependency>--> 这个依赖有什么用


这个依赖是用来支持Spring Boot的配置属性自动补全和提示的。它会生成一个用于IDE的元数据文件，用于提供配置属性的提示和文档。这样，在编写配置文件时，可以更方便地查看和使用Spring Boot的配置属性，并获得更好的开发体验。

 <properties>

<spring-boot.version>2.7.7</spring-boot.version>

</properties>

填写依赖的版本号，方便依赖的版本管理，避免依赖冲突

就像定义常量，依赖的版本就引用定义好的常量

<dependencyManagement> 

<dependencies>

。。。。

</dependencies>

<dependencyManagement> 

此中的依赖不会被继承，子模块引入其中的依赖不需要指定版本

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
</dependencies>

 在<dependencyManagement> 外面的依赖可以被继承到

二.common模块依赖

<?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">

    <name>common</name>
    <description>通用模块</description>

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

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

<!--        该依赖具有自动填充createTime updateTime功能-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus</artifactId>
        </dependency>

        <dependency>

        </dependency>

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

<!--导入继承的父模块的lombok依赖-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>

            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
        </dependency>


<!--配置动态数据源  需要父项目具有该依赖才可以使用，否则会报错-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>dynamic-datasource-spring-boot-starter</artifactId>

    </dependencies>



    <build>
        <plugins>
            <!-- 资源文件拷贝插件 -->
            <plugin>

                </configuration>
            </plugin>
        </plugins>

    </build>

</project>

 

三.api模块依赖

<?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>com.dmdd</groupId>
        <artifactId>GeneralCode</artifactId>
        <version>0.0.1</version>
    </parent>


    <artifactId>api</artifactId>
    <version>0.0.1</version>
    <name>api</name>
    <description>接口模块</description>

    <dependencies>
<!-- 该模块内部的依赖和内容会继承到此模块-->
        <dependency>
            <groupId>com.dmdd</groupId>
            <artifactId>common</artifactId>
            <version>0.0.1</version>
        </dependency>


  <dependency>
    <groupId>org.yaml</groupId>
    <artifactId>snakeyaml</artifactId>
    <version>1.27</version>
  </dependency>

        <!-- junit -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>
<!--        <dependency>-->
<!--            <groupId>org.springframework.boot</groupId>-->
<!--            <artifactId>spring-boot</artifactId>-->
<!--        </dependency>-->

<!--        <dependency>-->
<!--            <groupId>org.springframework.boot</groupId>-->
<!--            <artifactId>spring-boot-autoconfigure</artifactId>-->
<!--        </dependency>-->

<!--        代码生成器需要这个-->
        <dependency>
            <groupId>com.microsoft.sqlserver</groupId>
            <artifactId>mssql-jdbc</artifactId>
            <version>9.2.1.jre8</version>
        </dependency>


    </dependencies>

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

</project>

<parent>
<groupId>com.dmdd</groupId>
<artifactId>GeneralCode</artifactId>
<version>0.0.1</version>
</parent>

 继承了父模块  父模块中<dependencyManagement>的依赖不会被继承

<!-- 该模块内部的依赖和内容会继承到此模块-->
<dependency>
<groupId>com.dmdd</groupId>
<artifactId>common</artifactId>
<version>0.0.1</version>
</dependency>

引用了common模块

四.查看依赖树 

 

api模块中，common模块的依赖全部继承了， 父项目的依赖只继承了不在<dependencyManagement>里的依赖
