    <!-- 配置SpringMVC -->
    <!-- 1.開啟SpringMVC注解模式 -->
    <!-- 簡化配置： 
        (1)自動注冊DefaultAnootationHandlerMapping,AnotationMethodHandlerAdapter 
        (2)提供一些列：數(shù)據(jù)綁定，數(shù)字和日期的format @NumberFormat, @DateTimeFormat, xml,json默認讀寫支持 
    -->
    <mvc:annotation-driven />


    <!-- 2.靜態(tài)資源默認servlet配置
        (1)加入對靜態(tài)資源的處理：js,gif,png
        (2)允許使用"/"做整體映射
    -->
    <mvc:default-servlet-handler/>
     
    <!-- 3.配置jsp 顯示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.掃描web相關(guān)的bean -->
    <context:component-scan base-package="com.graduation.web" />

    <!--5.aop配置-->
    <aop:aspectj-autoproxy/>
</beans>

該配置的我都配置了，突然就請求不了了，控制臺總報這樣錯

No mapping found for HTTP request with URI [/graduation/seller/login] in DispatcherServlet with name 'mvc-dispatcher'
