GenericBeanDefinition

open class GenericBeanDefinition : AbstractBeanDefinition

GenericBeanDefinition is a one-stop shop for standard bean definition purposes. Like any bean definition, it allows for specifying a class plus optionally constructor argument values and property values. Additionally, deriving from a parent bean definition can be flexibly configured through the "parentName" property.

In general, use this GenericBeanDefinition class for the purpose of registering user-visible bean definitions (which a post-processor might operate on, potentially even reconfiguring the parent name). Use RootBeanDefinition / ChildBeanDefinition where parent/child relationships happen to be pre-determined.

Inheritors

AnnotatedGenericBeanDefinition

open class AnnotatedGenericBeanDefinition : GenericBeanDefinition, AnnotatedBeanDefinition

Extension of the org.springframework.beans.factory.support.GenericBeanDefinition class, adding support for annotation metadata exposed through the AnnotatedBeanDefinition interface.

This GenericBeanDefinition variant is mainly useful for testing code that expects to operate on an AnnotatedBeanDefinition, for example strategy implementations in Spring's component scanning support (where the default definition class is org.springframework.context.annotation.ScannedGenericBeanDefinition, which also implements the AnnotatedBeanDefinition interface).

ScannedGenericBeanDefinition

open class ScannedGenericBeanDefinition : GenericBeanDefinition, AnnotatedBeanDefinition

Extension of the org.springframework.beans.factory.support.GenericBeanDefinition class, based on an ASM ClassReader, with support for annotation metadata exposed through the AnnotatedBeanDefinition interface.

This class does not load the bean Class early. It rather retrieves all relevant metadata from the ".class" file itself, parsed with the ASM ClassReader. It is functionally equivalent to AnnotatedGenericBeanDefinition#AnnotatedGenericBeanDefinition(AnnotationMetadata) but distinguishes by type beans that have been scanned vs those that have been otherwise registered or detected by other means.
