    <!--会帮我们注册默认处理请求，参数和返回值的类，其中最主要的两个类：DefaultAnnotationHandlerMapping 和 AnnotationMethodHandlerAdapter ，分别为HandlerMapping的实现类和HandlerAdapter的实现类，从3.1.x版本开始对应实现类改为了RequestMappingHandlerMapping和RequestMappingHandlerAdapter。

 HandlerMapping的实现类的作用
 实现类RequestMappingHandlerMapping，它会处理@RequestMapping 注解，并将其注册到请求映射表中。

 HandlerAdapter的实现类的作用
 实现类RequestMappingHandlerAdapter，则是处理请求的适配器，确定调用哪个类的哪个方法，并且构造方法参数，返回值。

 当配置了mvc:annotation-driven/后，Spring就知道了我们启用注解驱动。然后Spring通过context:component-scan/标签的配置，会自动为我们将扫描到的@Component，@Controller，@Service，@Repository等注解标记的组件注册到工厂中，来处理我们的请求。
 表示将所有的文件，包含静态资源文件都交给spring mvc处理。就需要用到<mvc:annotation-driven />了。如果不加，DispatcherServlet则无法区分请求是资源文件还是mvc的注解，而导致controller的请求报404错误。

    <!--在springMVC-servlet.xml中配置<mvc:default-servlet-handler />后，会在Spring MVC上下文中定义一个o
    rg.springframework.web.servlet.resource.DefaultServletHttpRequestHandler，它会像一个检查员，对进入
    DispatcherServlet的URL进行筛查，如果发现是静态资源的请求，就将该请求转由Web应用服务器默认的Servlet处理，
    如果不是静态资源的请求，才由DispatcherServlet继续处理。
    一般Web应用服务器默认的Servlet名称是"default"，因此DefaultServletHttpRequestHandler可以找到它。
