	<!-- 以下为SpringMVC配置 -->
<!--
<mvc:annotation-driven /> 是一种简写形式，完全可以手动配置替代这种简写形式，简写形式可以让初学都快速应用默认配置方案。
<mvc:annotation-driven /> 会自动注册DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter 两个bean,是spring MVC为@Controllers分发请求所必须的。
并提供了：数据绑定支持，@NumberFormatannotation支持，@DateTimeFormat支持，@Valid支持，读写XML的支持（JAXB），读写JSON的支持（Jackson）。
后面，我们处理响应ajax请求时，就使用到了对json的支持。
后面，对action写JUnit单元测试时，要从spring IOC容器中取DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter 两个bean，
来完成测试，取的时候要知道是<mvc:annotation-driven />这一句注册的这两个bean。 -->
	<mvc:annotation-driven>
		<!-- 返回json数据，@response使用 -->
