<div>1、<context:component-scan base-package="com.eduoinfo.finances.bank.web"></context:component-scan> 作用</div>

<div>Spring 容器初始化的时候，会扫描 com.eduoinfo.finances.bank.web下标有 (@Component,@Service,@Controller,@Repository)

注解的类 纳入spring容器管理



在类上，使用以下注解，实现bean 的声明



@Component 泛指组件，当组件不好归类的时候，我们可以使用这个注解进行标注。



@Service 用于标注业务层组件



@Controller 用于标注控制层组件（如srping mvc的controller,struts中的action）



@Repository 用于标注数据访问组件，即DAO组件



示例：



@Controller 

@RequestMapping(value = "/test") 

public class TestController {



}



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



在类的成员变量上,使用以下注解，实现属性的自动装配



@Autowired : 按类的类型进行装配



@Resource (推荐) : 1 如果同时指定了name和type，则从<a href="http://lib.csdn.net/base/javaee" class="replace_word" title="Java EE知识库" target="_blank" style="color:#df3434; font-weight:bold;">spring</a>上下文中找到唯一匹配的bean进行装配，找不到则抛出异常 





 2. 如果指定了name，则从上下文中查找名称（id）匹配的bean进行装配，找不到则抛出异常 





 3.如果指定了type，则从上下文中找到类型匹配的唯一bean进行装配，找不到或者找到多个，都会抛出异常 



 4.如果既没有指定name，又没有指定type，则自动按照byName方式进行装配；如果没有匹配，则回退为一个原始类型进行匹配，如果匹配则自动装配； 





@Resource注解在字段上，这样就不用写setter方法了，并且这个注解是属于J2EE的，减少了与spring的耦合。 



示例：



@Resource 

private TestServiceImpl testServiceImpl;
