在springMVC中添加過濾器

在web.xml中填入如下代碼便可起到過濾作用 

<filter>
   <filter-name>encodingFilter</filter-name>
   <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
   <init-param>
    <param-name>encoding</param-name>
    <param-value>gb2312</param-value>
   </init-param>
 </filter>
 <filter-mapping>
       <filter-name>encodingFilter</filter-name>
       <url-pattern>*.ws</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
     <url-pattern>*.jsp</url-pattern>
 </filter-mapping> 

filter-mapping：爲所過濾的映射，如果有多個擴展名的話可以添加多個filter-mapping
