Class EnvironmentValueProvider

All Implemented Interfaces:

public class EnvironmentValueProvider extends AbstractMapConfigurationValueProvider
Searches for the configuration values in the system environment variables.

To handle shells that only allow underscores, it checks the following variations of a property:

  • - the original name
  • foo_bar - with underscores for periods (if any)
  • FOO.BAR - original, with upper case
  • FOO_BAR - with underscores and upper case
Any hyphen variant of the above would work as well, or even mix dot/hyphen variants.
