This code is the configuration file of the Maven project, which mainly configures two plug-ins:

1. spring-boot-maven-plugin: Used to package Spring Boot applications into executable JAR files. Among them, the mainClass attribute specifies the main class of the application, the layout attribute specifies the packaging format (here is ZIP), and the includes attribute specifies the dependent libraries that need to be included (here does not contain any dependent libraries).

2. maven-dependency-plugin: used to copy the third-party library that the project depends on to the lib directory of the project. Among them, the outputDirectory attribute specifies the output directory as ${project.build.directory}/lib.
