Spring Boot switch between different environment configuration

Generally, we will provide several sets of actual development environment in the configuration file, the format is probably as follows:

applcation.properties
 
application-dev.properties
 
application-test.properties
 
application-prod.properties

By way of using the profile, generally defined in applcation.properties spring.profiles.active variable values, such as want to open development environment's configuration file:

spring.profiles.active = prod

This is a personal feeling relatively simple method.
