What are the ways in which SpringBoot dynamically configures the Profile environment

Xiaobian to share with you the SpringBoot dynamic configuration Profile environment what are the ways, I believe most people do not know how, so share this article for everyone's reference, I hope you read this article after a great harvest, let's go to understand it!

The following example is an example of dynamically configured port numbers by modifying development and production environments:

Development environment port number is 8081

Production environment port number is 8082

Springboot configuration

Springboot has two configurations: properties and yaml or yml.

properties configuration

1. Configure the environment in application.properties.

Create two application-xx.properties

An application-dev.properties #development environment

An application-pro.properties #production environment

Modify in application.properties.

spring.profiles.active=pro #Switch to production

spring.profiles.active=dev #Switch to development environment

directory structure

2. Modify the environment configuration file by running the jar package

java -jar package file path--spring.profile.active=dev #Switch development environment

java -jar package file path--spring.profile.active =pro #Switch production environment

yaml mode configuration

yaml configuration is simpler than properties: a yaml file can replace the above three properties files; divide the environment by '---' three bars

#---These three bars are equivalent to creating multiple properties files---server: port: 8081spring: profiles: dev #specified environment name--server: port: 8082 spring: profiles: pro #specified environment name--- spring: profiles: active: pro #Configure Environment---
