Interface BeanSelectionProvider

All Superinterfaces:
ConfigurationProvider, ContainerProvider, PackageProvider
All Known Implementing Classes:
AbstractBeanSelectionProvider, StrutsBeanSelectionProvider
public interface BeanSelectionProvider extends ConfigurationProvider
A ConfigurationProvider that selects and aliases bean implementations.

Implementations of this interface are responsible for selecting which bean implementation to use for a given interface type. The selection is typically based on configuration properties that specify the bean name or class name.

The aliasing mechanism works as follows:

  1. Look for a bean by the name specified in the configuration property
  2. If found, alias it to the default name so it becomes the default implementation
  3. If not found, try to load the value as a class name and register it as a factory
  4. If class loading fails, delegate to ObjectFactory at runtime (useful for Spring bean names)
