方法一：<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>
