2、POM简介
POM文件（Project Object Model）是Maven项目的核心文件，它描述了Maven项目的基本信息和依赖关系。POM文件是一个XML文件，通常位于项目根目录下的pom.xml文件中。
POM文件包含以下信息：
- 项目的基本信息，如项目名称、版本号、描述等。
- 项目的依赖关系，包括依赖的外部库、插件等。
- 项目的构建配置，包括编译器版本、打包方式、测试配置等。
- 项目的开发者信息，包括开发者姓名、邮箱等。
POM文件的作用是：
- 管理项目的依赖关系，自动下载和安装依赖的库和插件。
- 管理项目的构建过程，自动编译、测试、打包和发布项目。
- 管理项目的版本号和发布历史，方便项目的版本控制和管理。
- 管理项目的开发者信息，方便项目的协作和交流。
总之，POM文件是Maven项目的核心文件，它提供了项目的基本信息和依赖关系，方便项目的管理和开发。
