注解的整体把握
1、<context:component-scan base-package="com.eduoinfo.finances.bank.web"></context:component-scan> 作用
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***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***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Spring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;
