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, org.springframework.beans.factory.support.BeanNameGenerator):
Alternatively, the class may provide a single constructor with one or more of the following supported parameter types:
See implementations and associated unit tests for usage examples.

Method Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default void`	`registerBeanDefinitions(AnnotationMetadata importingClassMetadata, BeanDefinitionRegistry registry)`	Register bean definitions as necessary based on the given annotation metadata of the importing `@Configuration` class.
`default void`	`registerBeanDefinitions(AnnotationMetadata importingClassMetadata, BeanDefinitionRegistry registry, BeanNameGenerator importBeanNameGenerator)`	Register bean definitions as necessary based on the given annotation metadata of the importing `@Configuration` class.

```
default void registerBeanDefinitions(AnnotationMetadata importingClassMetadata,
                                     BeanDefinitionRegistry registry,
                                     BeanNameGenerator importBeanNameGenerator)
```
    Register bean definitions as necessary based on the given annotation metadata of the importing @Configuration class.
    Note that BeanDefinitionRegistryPostProcessor types may not be registered here, due to lifecycle constraints related to @Configuration class processing.
    The default implementation delegates to registerBeanDefinitions(AnnotationMetadata, BeanDefinitionRegistry).
    Parameters:
    importingClassMetadata - annotation metadata of the importing class
    registry - current bean definition registry
    importBeanNameGenerator - the bean name generator strategy for imported beans: ConfigurationClassPostProcessor.IMPORT_BEAN_NAME_GENERATOR by default, or a user-provided one if ConfigurationClassPostProcessor.setBeanNameGenerator(org.springframework.beans.factory.support.BeanNameGenerator) has been set. In the latter case, the passed-in strategy will be the same used for component scanning in the containing application context (otherwise, the default component-scan naming strategy is AnnotationBeanNameGenerator.INSTANCE).
    Since:
    5.2

default void registerBeanDefinitions(AnnotationMetadata importingClassMetadata,
                                     BeanDefinitionRegistry registry)
```
    Register bean definitions as necessary based on the given annotation metadata of the importing @Configuration class.
    Note that BeanDefinitionRegistryPostProcessor types may not be registered here, due to lifecycle constraints related to @Configuration class processing.
    The default implementation is empty.
    Parameters:
    importingClassMetadata - annotation metadata of the importing class
    registry - current bean definition registry
