因为使用extreme需要在web.xml文件中配置，如果
<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>/*</url-pattern>
</filter-mapping>
写在
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springwork.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param->UTF-8</param->
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>*.xhtml</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
上面，则标单Post提交的时候会出现乱码，只有将字符filter写在上面，才有效。
