</init-param>
</servlet>
<servlet-mapping>
<setvlet-name>springMVC</setvlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

springmvc.xml:

<context:compent-scan base-package=""/>
<!-- 配置注解驱动 可以将request参数与绑定到controller参数上 -->
<mvc:annotation-driven/>
<!--静态资源映射-->
<mvc:resources mapping="" location=""/>
