Springboot different environments to read different configurations

1.3 Configuration files (more environments can be built multiple):

Application.properties (public config file)

Application-dev.properties (development environment)

Application-prod.properties (production environment)

2. Set application.properties, such as using the development environment with the following code, deployment as long as you change the dev to prod

Spring.profiles.active=dev

The environment public configuration is written in Application.properties.
Module-specific configuration is written in the corresponding application-{xxx}.properties file
When the program reads, the application.properties configuration is read first, and if it is not read, it is read from Application-{xxx}.properties.
