之間的區別 和

問題：

I'm learning Spring 3 and I don't seem to grasp the functionality behind <context:annotation-config> and <context:component-scan> . 我正在學習Spring 3，而且彷佛不太瞭解<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. 從我閱讀的內容來看，它們彷佛處理不一樣的註釋 （ @Required ， @Repository @Autowired等與@Component @Repository ， @Service @Component ， @Repository等），但從我閱讀的內容來看，它們註冊了相同的bean後處理器類。

To confuse me even more, there is an annotation-config attribute on <context:component-scan> . 更讓我感到困惑的是， <context:component-scan>上有一個annotation-config 屬性 。

Can someone shed some light on these tags? 有人能夠說明這些標籤嗎？ What's similar, what's different, is one superseded by the other, they complete each other, do I need one of them, both? 有什麼類似之處，有什麼不一樣之處，是一個被另外一個取代，它們彼此完成，我是否須要其中一個？
