web.xml配置：

<servlet>
      <servlet-name>dispatcher</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:springmvc.xml</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
      <servlet-name>dispatcher</servlet-name>
      <url-pattern>/</url-pattern>
</servlet-mapping>

servlet-name非常重要，默认情况下DispatcherSerlvet会自动尝试读取WEB-INF目录下名为servlet-name-servlet.xml的文件来加载应用程序上下文，这里对应的就是WEB-INF目录下的dispatcher-servlet.xml，如果配置
了contextConfigLocation（名字貌似是固定的）参数，设置上下文配置文件路径，自搭建为classpath:springmvc.xml，如果此参数不设置，默认加载WEB-INF路径下的application-Context.xml文件。

spring上下文配置文件dispatcher-servlet.xml，此例子对应classpath:springmvc.xml:
