springMVC主要有以下四个配置：
1.配置组件扫描，必配，组件扫描会扫描包下的所有的Controller类
<!-- 配置组件扫描 -->
<context:component-scan base-package="controller" />2.配置MVC注解扫描，必配，和组件扫描搭配，相当于同时配置了HandlerMapping和Controller
<!-- 配置MVC注解扫描 -->
<mvc:annotation-driven />3.配置视图解析器，选配，视图解析器是为了当html，jsp等前端文件放到WEB-INF/的路径下时，浏览器不能直接访问，就需要使用视图解析器来访问相应的前端文件。
<!-- 配置视图解析器， -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/" /><!-- 前缀 -->
<property name="suffix" value=".jsp" /><!-- 后缀 -->
</bean>4.配置拦截器，选配，拦截器是拦截tomcat容器和spring容器之间的交互信息，主要是用于验证用户在访问该网页时是否登陆
<!-- 配置拦截器 -->
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/*"/>
<bean class="interceptors.SomeInterceptor"/>
</mvc:interceptor>
