java SpringBoot switches between different operating environments (production environment, development environment, test environment) SpringBoot configures multiple different operating environments [multi-file version]

Background: The same set of Spring Boot applications will be installed in different environments, such as: development, testing, production, etc. Among them, the most modified ones are nothing more than the configuration of the database address, server port, etc.

Use the profile function to switch between different operating environments (production environment, development environment, and test environment)
