java web pom.xml

Posted 2023-04-05

java web 开发，maven项目，pom.xml配置中，有<parent>和<dependencies>两个节点，它们的本质区别是什么（在我理解两者都是去仓库下载东西到本地仓库，不是很清楚本质区别到底是什么）
有哪位大神知道的，给小弟讲解下，不胜感激！

如果这个java web项目的pom文件中，同时有parent和dependencies两个节点，那么在你打war包时，parent里的dependencies依赖也会被引入到web项目中。这只是个配置方式的问题。项目自己的pom里的dependencies只会在项目内部使用，那些被抽成parent的pom一般都是公用dependency或者其它配置，既可以给你的web项目用，又可以给其它任何maven项目用。 参考技术A parent是上级pom.xml

dependencies是依赖的项目（.jar），同级的追问

感谢您的回答，请问parent是指本项目只继承父项目的dependencies吗？

1. 基本pom.xml结构

<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/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.marving</groupId>
    <artifactId>sshDemo</artifactId>
    <packaging>war</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <name>SpringMVC_Spring_Hibernate</name>
    <url>http://maven.apache.org</url>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
    </properties>
