Filter配置问题，在线等

现在是  一个  Filter 处理中文的 问题 由于是 两部分开发 自己这部分配置上 别人的就乱码 ，不配置自己的就乱码 
我的文件 jsp 都在 一个 目录下，我能否 通过配置 绕过 他人的代码 ，只对自己的代码起作用。 <filter>
   <filter-name>encodeFilter</filter-name>
   <filter-class>com.pkpm.houseManager.filter.CharacterEncodingFilter</filter-class>
   <init-param>
      <param-name>encoding</param-name>
      <param-value>gb2312</param-value>
   </init-param>
   <init-param>
          <param-name>ignore</param-name>
          <param-value>true</param-value>
       </init-param>
   
</filter>
