配置web.xml

    <!--配置DispatherServlet-->
    <servlet>
        <servlet-name>killone-dispather</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--配置springmvc需要加载的配置文件-->

    </servlet>

    <servlet-mapping>
        <servlet-name>killone-dispather</servlet-name>
        <!--默认匹配所有请求-->
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

配置spring-web.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!--配置springMVC-->
    <!--1、开启springMVC注解模式-->
    <!--这步做了什么：
        1、自动注册DefaultAnnotationHandlerMapping,AnnotationMethodHandlerMapping
        2、提供一系列功能：数据绑定，数字和日期的格式化，@DateTimeFormat,@NumberFormat,
        xml,json的默认支持
    -->
    <mvn:annotation-driven/>
    <!--2、静态资源默认servlet配置-->
    <!--这步做了什么
        1、加入对静态资源处理：js，png，jpg
        2、允许使用"/"做映射
    -->
    <mvc:default-servlet-handler/>

    <!--3、配置jsp，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.jimo.web"/>
</beans>
