spring编码过滤器

由于编码的不一致，我们可以在web.xml中配置spring的中文过滤器
<!-- spring character filter --> 
   <filter> 
      <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> 
   <filter-mapping> 
    <filter-name>encodingFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
   </filter-mapping>
