Use spring-boot-maven-plugin plugin to package SpringBoot application method

Spring-boot-maven-plugin plugin package SpringBoot application

spring-boot-maven-plugin can make Spring Boot applications into jar packages with dependencies.

That is, the package not only contains the application's own code, but also contains the dependencies configured in it.

Revise

               <artifactId>spring-boot-maven-plugin</artifactId>

Pack

$ mvn compile
$ mvn package spring-boot:repackage

In this way, the generated jar package contains the project dependencies, and the generated jar package is located in the project's target folder.

Compare the similarities and similarities of the two directories

Assume that the project structure is

|-src
  |- main
     |- java
       |- cn
  |- resources
     |- 
|-

	mv package	mvn package spring-boot:repackage
jar package size	Very small, usually only a few dozen to hundreds of KB	It is too large, usually more than ten MB, depending on how much the project depends on
Table of contents	-cn folder is the compiled class file -META-INF folder contains project files - Project configuration file	-BOOT-INF contains the compiled class file and project configuration file project-related dependencies -META-INF internally contains file l
