Interface ConfigurationScanner

All Known Implementing Classes:

BlueprintConfigurationScanner, DefaultConfigurationScanner

public interface ConfigurationScanner

Convenience scanner locating suitable Spring configurations inside an OSGi bundle. This interface can be implemented to customize Spring-DM default definition of a 'Spring-powered' bundle by using different locations or supplying defaults for bundles that do not provide a proper configuration.

Additionally, non-XML configurations (for example annotation-based) can be plugged in. This would normally imply a custom application context creator as well.

Note:It is strongly recommended that the default locations (META-INF/spring/*.xml or Spring-Context manifest header) are supported (through chaining or by extending the default implementation) to avoid breaking bundles using them.

This interface is intended for usage with the default OsgiApplicationContextCreator implementation.
