Interface PropertiesSource

All Known Subinterfaces:
LoadablePropertiesSource
public interface PropertiesSource
A source of property values for the Camel PropertiesComponent when resolving property placeholders.

The properties component consults all registered sources (system properties, environment variables, .properties files, beans, vaults, and so on) to resolve a placeholder. A source can implement Ordered to control its precedence; the source with the highest precedence (the lowest number) is consulted first. Sources whose properties can be loaded eagerly in bulk implement LoadablePropertiesSource, and the built-in sources are created via PropertiesSourceFactory.

See Using PropertyPlaceholder in the Camel user manual.
