when using Idea before, because it is a non-springboot project, create three new
dev,test,prod environments under the src/main/resources directory, and then switch to the environment under profiles under Maven projects on the right side of the IDEA.

now three springboot, environments are used for different configurations: application-dev/test/pro.properties, needs to switch manually in application.properties .

spring.profiles.active

can you also switch with the next button under profiles under Maven projects on the right side of IDEA?
