看dubbo源代码. xml里配置的dubbo consumer对应的ReferenceBean. 是spring的FactoryBean.

一般情况下FactoryBean 直接配置在xml里,然后spring自动注入.

但现在需要手动(编程式)将FactoryBean手动注入到容器中.

运用debug的原理的原理发现FactoryBean的getObject()调用堆栈是. 但这里已经是被spring接管了,好奇这个Object什么时候注册到spring的context中的,

    然后就查看new ReferenceBean() [无父类]的地方,发现也没有注入到context容器中.

    然后就蒙逼了, 只能从spring的基础功能入手. 何时注入FactoryBean 到何时注入Bean. 再到dubbo的consumer xml解析.终于找到一篇文章: Dubbo源码分析（二）：Dubbo之消费端（Consumer） { http://www.cnblogs.com/huqianliang/p/5673652.html }

    然后看这里的源代码,恍然大悟, spring都是通过BeanDefinition注入的.后面再进行最后的finishBeanFactoryInitialization
