<!-- 配置spring -->
<!-- 1:开启SpringMVC注解模式 -->
<!-- 简化配置：
（1）自动注册DefaultAnnotationHandlerMapping，AnnotationMethodHandlerAdapter
（2）提供一系列：数据绑定，数字和日期的format @NumberFormat，@DataTimeFormat，xml，json默认读写支持
-->
<mvc:annotation-driven/>
<!-- 2：servlet-mapping 映射路径："/" -->
<!-- 静态资源默认servlet配置
1.加入对静态资源的处理
2.欲需使用"/"做整体映射
-->
<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 name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!-- 4：扫描web相关的bean -->
<context:component-scan base-package="com.cgj.spring.mvc.controller">
<!-- 只扫描@Controller标注的类，不扫描其他标注的类 -->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
