iBatis查询字段丢失的问题.
在用ibatis查询时,ibatis把一些字段给丢掉了.
配置如下：
<select   id= "readMovie "   parameterClass= "java.lang.Integer "   resultClass= "movie ">
select   id,   cn_name,   keyword,   en_name,   area,
language,   play_Time,   corporation,   show_Time,   create_Time,
recommend,   introduction,   grade,   format,   quality,  
number,   orders   from   vod_movie
where   id   =   #movieId#
</select>


DAO层查询代码下如：
public   Movie   readMovie(int   movieId)   {
logger.debug( "读取影片信息.   传入参数:   movieId   =   "   +   movieId);

return   (Movie)getSqlMapClientTemplate().queryForObject( "readMovie ",   new   Integer(movieId));
}

要询询完成后，发现ibatis把我的一些字段自动给去掉：日志如下：
  -   读取影片信息.   传入参数:   movieId   =   1

大家注意看上面的一行,只有在Header:[i
d,   keyword,   area,   language,   corporation,   recommend,   introduction,   grade,   format,   quality,   number,   orders]之类的字段才能取到值，其它字段为null。无法得值。

数据库确定有值。不知道是什么问题。
