在spring.jar包的org.springframework.web.filter包下有个CharacterEncodingFilter.java

把spring.jar放进工程的lib里，然后在web.xml文件中<servlet>元素前加以下代码

注意要把CharacterEncodingFilter放在其他过滤器之前声明。

<!-- 著名 Character Encoding 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>gbk</param-value> <!-- //指定字符集  -->
         </init-param>
         <init-param>
             <!--  //当已经有字符集时，是否用本过滤器的字符集替换 -->
             <param-name>forceEncoding</param-name>
           <param-value>true</param-value>
        </init-param>
     </filter>
     <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
     </filter-mapping>
    <!--其他某过滤器 -->
    <filter>
        <filter-name>eXtremeExport</filter-name>
        <filter-class>

    </filter>
    <filter-mapping>
