关于springboot:Spring-Boot-如何处理Autowired二

Spring Boot 如何解决@Autowired（一）
这篇小文可知AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues()最终执行对@Autowired的属性实例进行织入；而后以DefaultListableBeanFactory.resolveDependency()->DefaultListableBeanFactory.doResolveDependency()->DependencyDescriptor.resolveCandidate()->beanFactory.getBean()的链条进行创立field bean实例：

public Object resolveDependency(){
    //省略其余code
    {
            Object result = getAutowireCandidateResolver().getLazyResolutionProxyIfNecessary(
                    descriptor, requestingBeanName);
            if (result == null) {
                result = doResolveDependency(descriptor, requestingBeanName, autowiredBeanNames, typeConverter);
            }
            return result;
        }
}

public Object resolveCandidate(String beanName, Class<?> requiredType, BeanFactory beanFactory)
            throws BeansException {

        return beanFactory.getBean(beanName);
    }

当初是不是恍然大悟了？整个调用链路就清晰起来了～，原本有点懒，就不总结了，总结就交给读者敌人了，欢送留言加友探讨～
