同学，检查一下web.xml是不是和视频里面一致：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns="http://java.sun.com/xml/ns/javaee"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
        id="WebApp_ID" version="2.5">
  <display-name>Archetype Created Web Application</display-name>

   <filter>
       <filter-name>characterEncodingFilter</filter-name>
       <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
       <init-param>
           <param-name>encoding</param-name>
           <param-value>UTF-8</param-value>
       </init-param>
       <init-param>
           <param-name>forceEncoding</param-name>
           <param-value>true</param-value>
       </init-param>
   </filter>
   <filter-mapping>
       <filter-name>characterEncodingFilter</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>

   <listener>
       <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
   </listener>

   <listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>
   <context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>
           classpath:applicationContext.xml
       </param-value>
   </context-param>
   <!-- springmvc配置 -->
   <servlet>
       <servlet-name>dispatcher</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
       <servlet-name>dispatcher</servlet-name>
       <url-pattern>*.do</url-pattern>
   </servlet-mapping>
</web-app>

然后陆续检查dispatcher-servlet.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" xmlns:p="http://www.springframework.org/schema/p"
      xmlns:context="http://www.springframework.org/schema/context"
      xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop"
      xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
  http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
  http://www.springframework.org/schema/mvc
  http://www.springframework.org/schema/mvc/spring-mvc.xsd">
   <context:component-scan base-package="com.mmall" annotation-config="true"/>
   <mvc:annotation-driven>
       <mvc:message-converters>
           <bean class="org.springframework.http.converter.StringHttpMessageConverter">
               <property name="supportedMediaTypes">
                   <list>
                       <value>text/plain;charset=UTF-8</value>
                       <value>text/html;charset=UTF-8</value>
                   </list>
               </property>
           </bean>
           <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
               <property name="supportedMediaTypes">
                   <list>
                       <value>application/json;charset=UTF-8</value>
                   </list>
               </property>
           </bean>
       </mvc:message-converters>
   </mvc:annotation-driven>
   <!-- 文件上传 -->
   <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
       <property name="maxUploadSize" value="10485760"/> <!-- 10m -->
       <property name="maxInMemorySize" value="4096" />
       <property name="defaultEncoding" value="UTF-8"></property>
   </bean>
</beans>

继续检查applicationContext.xml及其子文件applicationContext-datasource.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" xmlns:aop="http://www.springframework.org/schema/aop"
      xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
      xmlns:context="http://www.springframework.org/schema/context"
      xsi:schemaLocation="
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">
   <context:component-scan base-package="com.mmall" annotation-config="true"/>
   <!--<context:annotation-config/>-->
   <aop:aspectj-autoproxy/>
   <import resource="applicationContext-datasource.xml"/>
</beans>

applicationContext-datasource.xml太长，暂时不列
