With the MicroProfile-Config API, there is a new and easy way to deal with configuration properties in an application. The MicroProfile-Config API allows you to access config and property values from different sources, like:
- System.getProperties() (ordinal=400)
- System.getenv() (ordinal=300)
- all META-INF/microprofile-config.properties files
Developers can find a good introduction into the MicroProfile Config API here. Of course, developers can also implement your own config source. However, most of the examples are based on reading custom config values from an existing file, like in the example here.
