<div>1、<context:component-scan base-package="com.eduoinfo.finances.bank.web"></context:component-scan> 作用</div>
<div>Spring 容器初始化的時候，會掃描 com.eduoinfo.finances.bank.web下標有 (@Component,@Service,@Controller,@Repository)
註解的類 納入spring容器管理

在類上，使用以下註解，實現bean 的宣告

@Component 泛指元件，當元件不好歸類的時候，我們可以使用這個註解進行標註。

@Service 用於標註業務層元件

@Controller 用於標註控制層元件（如srping mvc的controller,struts中的action）

@Repository 用於標註資料訪問元件，即DAO元件

示例：

@Controller 
@RequestMapping(value = "/test") 
public class TestController {

}

------------------------------------------------------------------------------------------------------------------

在類的成員變數上,使用以下註解，實現屬性的自動裝配

@Autowired : 按類的型別進行裝配

@Resource (推薦) : 1 如果同時指定了name和type，則從<a href="http://lib.csdn.net/base/javaee" class="replace_word" title="Java EE知識庫" target="_blank" style="color:#df3434; font-weight:bold;">spring</a>上下文中找到唯一匹配的bean進行裝配，找不到則丟擲異常 


    2. 如果指定了name，則從上下文中查詢名稱（id）匹配的bean進行裝配，找不到則丟擲異常  


    3.如果指定了type，則從上下文中找到型別匹配的唯一bean進行裝配，找不到或者找到多個，都會丟擲異常 

    4.如果既沒有指定name，又沒有指定type，則自動按照byName方式進行裝配；如果沒有匹配，則回退為一個原始型別進行匹配，如果匹配則自動裝配； 


@Resource註解在欄位上，這樣就不用寫setter方法了，並且這個註解是屬於J2EE的，減少了與spring的耦合。 

示例：

@Resource 
private TestServiceImpl testServiceImpl;
