ReferenceAnnotationBeanPostProcessor inherited AnnotationInjectedBeanPostProcessors that implements the interface postProcessPropertyValues ​​InstantiationAwareBeanPostProcessorAdapter approach, members of the swath @Reference annotated injection ReferenceBean objects:

@Override
    public PropertyValues postProcessPropertyValues(
            PropertyValues pvs, PropertyDescriptor[] pds, Object bean, String beanName) throws BeanCreationException {

        InjectionMetadata metadata = findInjectionMetadata(beanName, bean.getClass(), pvs);
        try {
            metadata.inject(bean, beanName, pvs);
        } catch (BeanCreationException ex) {
            throw ex;
        } catch (Throwable ex) {
            throw new BeanCreationException(beanName, "Injection of @" + getAnnotationType().getName()
                    + " dependencies is failed", ex);
        }
        return pvs;
}

findInjectionMetadata will identify all fields and methods and packaged into @Reference metadata, metadata.inject method in, calls the method injectElement inject, and then call the method inject AnnotatedFieldElement of:

 public class AnnotatedFieldElement extends InjectionMetadata.InjectedElement {

        private final Field field;

        private final A annotation;

        private volatile Object bean;

        protected AnnotatedFieldElement(Field field, A annotation) {
            super(field, null);
            this.field = field;
            this.annotation = annotation;
        }

        @Override
        protected void inject(Object bean, String beanName, PropertyValues pvs) throws Throwable {

            Class<?> injectedType = field.getType();

            Object injectedObject = getInjectedObject(annotation, bean, beanName, injectedType, this);

            ReflectionUtils.makeAccessible(field);

            field.set(bean, injectedObject);

        }

    }

 

 protected Object getInjectedObject(A annotation, Object bean, String beanName, Class<?> injectedType,
                                       InjectionMetadata.InjectedElement injectedElement) throws Exception {

        String cacheKey = buildInjectedObjectCacheKey(annotation, bean, beanName, injectedType, injectedElement);

        Object injectedObject = injectedObjectsCache.get(cacheKey);

        if (injectedObject == null) {
            injectedObject = doGetInjectedBean(annotation, bean, beanName, injectedType, injectedElement);
            // Customized inject-object if necessary
            injectedObjectsCache.putIfAbsent(cacheKey, injectedObject);
        }

        return injectedObject;

    }

DoGetInjectedBean which is ReferenceAnnotationBeanPostProcessor rewritten:

 @Override
    protected Object doGetInjectedBean(Reference reference, Object bean, String beanName, Class<?> injectedType,
                                       InjectionMetadata.InjectedElement injectedElement) throws Exception {

        String referencedBeanName = buildReferencedBeanName(reference, injectedType);

        ReferenceBean referenceBean = buildReferenceBeanIfAbsent(referencedBeanName, reference, injectedType, getClassLoader());

        cacheInjectedReferenceBean (referenceBean, injectedElement);

        Object proxy = buildProxy(referencedBeanName, referenceBean, injectedType);

        return proxy;
    }

Here you can see a referenceBean construct and return a proxy, real proxy is actually injected
