<!-- 配置SpringMVC -->
<!-- 1.开启SpringMVC注解模式 -->
<!-- 简化配置： (1)自动注册DefaultAnootationHandlerMapping,AnotationMethodHandlerAdapter
(2)提供一些列：数据绑定，数字和日期的format @NumberFormat, @DateTimeFormat, xml,json默认读写支持 -->
<mvc:annotation-driven />
<!-- 2.静态资源默认servlet配置 (1)加入对静态资源的处理：js,gif,png (2)允许使用"/"做整体映射 -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:default-servlet-handler />
<!-- 3.定义视图解析器 -->

<property name="suffix" value=".html"></property>

<property name="maxUploadSize" value="10485760000"></property><!-- 最大上传文件大小 -->

<!-- 在spring-mvc.xml文件中加入这段配置后，spring返回给页面的都是utf-8编码了 -->
