解决方案：

将web.xml中的   /*.do  修改为  *.do

<!-- 配置核心控制器 -->

  <servlet>

      <servlet-name>dispatcherServlet</servlet-name>

      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

      <!-- 指定配置文件的路径 -->

      <init-param>

          <!-- 注意：任何框架的参数名都可以在代码里面找到 -->

          <param-name>contextConfigLocation</param-name>

          <param-value>classpath:spring-mvc.xml</param-value>

      </init-param>

  </servlet>

  <servlet-mapping>

      <servlet-name>dispatcherServlet</servlet-name>

      <url-pattern>/*.do</url-pattern>  修改为   <url-pattern>*.do</url-pattern>
 </servlet-mapping>
