Class ReferenceAnnotationBeanPostProcessor

java.lang.Object

org.apache.dubbo.config.spring.beans.factory.annotation.AbstractAnnotationBeanPostProcessor

org.apache.dubbo.config.spring.beans.factory.annotation.ReferenceAnnotationBeanPostProcessor

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.config.InstantiationAwareBeanPostProcessor, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.support.MergedBeanDefinitionPostProcessor, org.springframework.context.ApplicationContextAware, org.springframework.context.EnvironmentAware

public class ReferenceAnnotationBeanPostProcessor
extends AbstractAnnotationBeanPostProcessor
implements org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor

Step 1: The purpose of implementing BeanFactoryPostProcessor is to scan the registration reference bean definition earlier, so that it can be shared with the xml bean configuration.

Step 2: By implementing InstantiationAwareBeanPostProcessor, inject the reference bean instance into the fields and setter methods which annotated with DubboReference.

Since:

2.5.7
