   <!--1.配置springMVC前端控制器(是总的控制中心  被拦截的url会汇聚到该servlet) -->  
    <servlet>  
        <servlet-name>springmvc</servlet-name>    
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
     <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springmvc-servlet.xml</param-value>
      </init-param>
        <load-on-startup>1</load-on-startup>  <!-- tomcat启动后立即加载 -->      
   </servlet>  
      
      
      <!--配置Spring -->
      <context-param> 
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:springmvc-servlet.xml</param-value>
      </context-param>

      
    <!--2. 配置spring拦截的url模板  以.do结尾的url-->  
    <servlet-mapping>  
        <servlet-name>springmvc</servlet-name>  
        <url-pattern>*.do</url-pattern>  
    </servlet-mapping>  
      
      
    <!--3. 注册配置文件读取器，监听spring配置文件的变化 -->  
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>   
   
  <!-- 指定spring配置文件位置 -->
  <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:springmvc-servlet.xml</param-value>
  </context-param>
     
    
    <!--5. 编码字符集统一为UTF-8（过滤器） -->  
    <filter>  
        <display-name>encodingFilter</display-name>  
        <filter-name>encodingFilter</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>  
    </filter>
