SpringBoot分离打Jar包的两种配置方式
作者:SerikaOnoe
这篇文章主要介绍了SpringBoot分离打Jar包的两种配置方式,方式一是基于maven-jar-plugin,方式二是基于spring-boot-maven-plugin,文中结合实例代码给大家介绍的非常详细,需要的朋友可以参考下
SpringBoot分离打Jar包的两种方式
方式一:基于maven-jar-plugin
此方式基于这个小伙伴的配置改的:https://www.jb51.net/article/188606.htm
注意
- 这种方式打包出来的Jar基于插件提供的类加载器启动:
org.springframework.boot.loader.PropertiesLauncher
- 所有依赖包(包括systemScope),会通过插件
maven-dependency-plugin
自动复制到lib
目录 - 所有资源文件,会通过插件
maven-resources-plugin
自动复制到config
目录 - 此方式打包后,需要指定参数启动
-Dloader.path=lib路径,config路径
- 打包完后部署需要的文件清单:(在
target/
目录下都可以看到)config/**
:所有resources下的资源文件lib/**
:所有lib包,包括本地依赖xxx.jar
:应用Jar
- 运行:
java -Dloader.path=lib,config -Dspring.profiles.active=dev -jar main.jar

方式二:基于spring-boot-maven-plugin
注意
- 这种方式打包出来的Jar基于插件提供的类加载器启动:
org.springframework.boot.loader.PropertiesLauncher
- 所有依赖包(包括systemScope),会通过插件
maven-dependency-plugin
自动复制到lib
目录 - 所有资源文件,会通过插件
maven-resources-plugin
自动复制到config
目录 - 此方式打包后,需要指定参数启动
-Dloader.path=lib路径,config路径
- 打包完后部署需要的文件清单:(在
target/
目录下都可以看到)config/**
:所有resources下的资源文件lib/**
:所有lib包,包括本地依赖xxx.jar
:应用Jar
- 运行:
java -Dloader.path=lib,config -Dspring.profiles.active=dev -jar main.jar
