Interface ImportBeanDefinitionRegistrar

All Known Implementing Classes:

AutoProxyRegistrar

public interface ImportBeanDefinitionRegistrar

Interface to be implemented by types that register additional bean definitions when processing @Configuration classes. Useful when operating at the bean definition level (as opposed to @Bean method/instance level) is desired or necessary.

Along with @Configuration and ImportSelector, classes of this type may be provided to the @Import annotation (or may also be returned from an ImportSelector).

An ImportBeanDefinitionRegistrar may implement any of the following Aware interfaces, and their respective methods will be called prior to registerBeanDefinitions(org.springframework.core.type.AnnotationMetadata, org.springframework.beans.factory.support.BeanDefinitionRegistry):

• BeanFactoryAware
• BeanClassLoaderAware
• ResourceLoaderAware

See implementations and associated unit tests for usage examples.
