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>
