The routes for HTTP services can be found in the classes available at the controller folder.

Note:

  • The mentioned package does not include the routes enabled by the Spring OAuth2 plugin.

The authentication server and the security options were set at the security package classes.

All exceptions will be properly handled at the RestExceptionHandler.java class.

The environment variables class at the settings package, will serve information previously configured at the application.yml file, available at the resources folder. This approach intends to organize static data and simplify constants usage through the entire application.
