<!-- 配置springMVC -->
<!-- 1:开启SpringMVC注解模式 -->
<!-- 作用（1）自动注册DefaultAnnotationHandleMapping,AnnotationMethodHandlerAdapter注解 -->
<!-- 作用（2）提供一系列：数据绑定，数字和日期的format(格式化) @NumberFormat,@DataTimeFormat,xml,json默认读写支持 -->
<mvc:annotation-driven />

<!-- 2：静态资源默认servlet配置 -->
<!-- 作用（1）加入对静态资源的处理：js，gif,png -->
<!-- 作用（2）允许使用"/"做整体映射 (servlet-mapping 映射路径：“/”)-->
<mvc:default-servlet-handler />

<!-- 3：配置jsp 显示ViewResolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"  value="org.springframework.web.servlet.view.JstlView"></property>
<property name="prefix"  value="/WEB-INF/jsp"></property>

<!-- 4：扫描web相关的bean -->
<context:component-scan base-package="org.seckill.web"/>
</bean>
