Interface ConfigSourceProvider

All Known Implementing Classes:

PropertiesConfigSourceProvider

public interface ConfigSourceProvider

Implement this interfaces to provide multiple ConfigSources. This is e.g. needed if there are multiple property files of a given name on the classpath but they are not all known at compile time.

If a single ConfigSource exists, then there is no need to register it using a custom implementation of ConfigSourceProvider, it can be registered directly as a ConfigSource.

A ConfigSourceProvider will get picked up via the ServiceLoader mechanism and can be registered by providing a META-INF/services/org.eclipse.microprofile.config.spi.ConfigSourceProvider file which contains the fully qualified classname of the custom ConfigSourceProvider.
