之间的区别 和

问题：

I'm learning Spring 3 and I don't seem to grasp the functionality behind <context:annotation-config> and <context:component-scan> . 我正在学习Spring 3，而且彷佛不太了解<context:annotation-config>和<context:component-scan> 。

From what I've read they seem to handle different annotations ( @Required , @Autowired etc vs @Component , @Repository , @Service etc), but also from what I've read they register the same bean post processor classes. 从我阅读的内容来看，它们彷佛处理不一样的注释 （ @Required ， @Repository @Autowired等与@Component @Repository ， @Service @Component ， @Repository等），但从我阅读的内容来看，它们注册了相同的bean后处理器类。

To confuse me even more, there is an annotation-config attribute on <context:component-scan> . 更让我感到困惑的是， <context:component-scan>上有一个annotation-config 属性 。

Can someone shed some light on these tags? 有人能够说明这些标签吗？ What's similar, what's different, is one superseded by the other, they complete each other, do I need one of them, both? 有什么类似之处，有什么不一样之处，是一个被另外一个取代，它们彼此完成，我是否须要其中一个？
