SpringBoot下Maven-多环境打包配置详解

在实际开发过程中，可能需要不断进行环境的切换和打包部署，通常我们会选择在application.properties中修改不同环境对应的配置文件，这种方式不仅效率低，而且很容易发生错误，造成不必要的麻烦降低工作效率。maven提供了多环境配置，可以方便实现不同环境的配置切换和打包。

多环境打包

pom.xml文件加上根据环境来打包.为了不把多余的其它环境的配置打到包里面。

打包命令

mvn clean package
mvn clean package -Pdev
mvn clean package -Ptest
mvn clean package -Pprod
