        <!-- 自动扫描 com.imooc.beanannotation包下所有类的注解-->
        <context:component-scan base-package="com.imooc.beanannotation"></context:component-scan>

 </beans>

实现Autowired注解注入的步骤：

1.在类上添加响应的注解（@Component @Repository @Service @Controller）使该类能被自动扫描到

2.在需要注入容器的属性或对象上添加@Autowired注解 –（可以将@Autowired注解理解为传统的setter方法）

相关实现代码（引入List和Map）

@Component("i")
public class BeanInvoker {

    @Autowired
    private List<BeanInterface>list;

    @Autowired
    private Map<String,BeanInterface> map;

    public void say() {
        if (null!=list) {
            System.out.println("list");
            for(BeanInterface bean:list){
                System.out.println(bean.getClass().getName());
            }
        }else {
            System.out.println("List<BeanInterface>list is null !!!!!!!");
        }

        if (null!=map&&0!=map.size()) {
            for (Map.Entry<String, BeanInterface>  entrty : map.entrySet()) {

                System.out.println(entrty.getKey()+"///**///"+ entrty.getValue().getClass().getName());

            }
        }
    } 
 }
 </beans>
