使用Spring的CharacterEncodingFilter应注意的问题

这是我的web.xml中配置:
<!-- 列表组件导出过滤器 -->
    <filter>
        <filter-name>eXtremeExport</filter-name>
        <filter-class>
            org.extremecomponents.table.filter.ExportFilter
        </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>eXtremeExport</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>
    <!-- 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>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
看不出有什么问题,可当我插入测试数据时全是乱码.
数据库本身是没有问题的.

后来终于找到了解决的方法,原创列表组件的filter对
CharacterEncodingFilter的过滤有影响.调整一下顺序就行了.
<!-- 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>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- 列表组件导出过滤器 -->
    <filter>
        <filter-name>eXtremeExport</filter-name>
        <filter-class>
            org.extremecomponents.table.filter.ExportFilter
        </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>eXtremeExport</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>
调整后CharacterEncodingFilter表现良好,一切正常.就不会再出来
乱码的问题了.
