pom.xml 是 Maven 项目的核心配置文件，用于描述项目的基本信息、依赖关系、构建配置等。下面是对 pom.xml 文件中常见元素的详解：
<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">
project元素是pom.xml文件的根元素，包含整个 Maven 项目的配置信息。xmlns命名空间用于指定 XML 文件的命名空间。xsi:schemaLocation指定 XML 文件的 XSD（XML Schema Definition）文件的位置，用于验证 XML 文件的结构。
<modelVersion>4.0.0</modelVersion>
modelVersion指定了 Maven 的 POM 模型版本，当前版本是 4.0.0。
<groupId>com.example</groupId>
<artifactId>example-project</artifactId>
<version>1.0.0</version>
<packaging>jar</packaging>
groupId定义了项目所属的组织或者包名。artifactId定义了项目的唯一标识符。version定义了项目的版本号。packaging定义了项目的打包方式，如jar、war等。
<dependencies>
<!-- 项目依赖配置 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.6.2</version>
</dependency>
<!-- 其他依赖项 -->
</dependencies>
dependencies元素定义了项目的依赖配置，包含一组dependency元素。- 每个
dependency元素描述一个依赖项，包括groupId、artifactId、version等。
<build>
<plugins>
<!-- 构建插件配置 -->
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.6.2</version>
</plugin>
<!-- 其他构建插件配置 -->
</plugins>
</build>
build元素定义了项目的构建配置，包含一组plugin元素。- 每个
plugin元素描述一个构建插件，包括groupId、artifactId、version等。
