类 BeanDefinitionHolder

java.lang.Object

org.springframework.beans.factory.config.BeanDefinitionHolder

所有已实现的接口:

BeanMetadataElement

直接已知子类:

BeanComponentDefinition

public class BeanDefinitionHolder
extends Object
implements BeanMetadataElement

Holder for a BeanDefinition with name and aliases. Can be registered as a placeholder for an inner bean.

Can also be used for programmatic registration of inner bean definitions. If you don't care about BeanNameAware and the like, registering RootBeanDefinition or ChildBeanDefinition is good enough.
