iBatis resultMap出错

在操作休假功能时，错误：
ERROR [http-8080-3] - 执行：class com.ving.xzfw.persistence.impl.CaseDaoImpl.getList()方法出错！
ERROR [http-8080-3] - SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [null]; error code [0];

ERROR [http-8080-3] - 错误发生在：HolidayDaoSerivice.insertHoliday(Holiday holi)方法中！
ERROR [http-8080-3] - 调用updateOrInsert方法失败

分析：
这个错误指出resultMap里有问题。说错误发生在设置某一个属性的时候，出现null!
但没有指明那个属性（也就是对应的字段）。
看下配置文件
    <resultMap id="HolidayResult" class="HolidayObject">
        <result property="holiId" column="holiid"/>
        <result property="holiType" column="holiType"/>
        <result property="holiStartDate" column="holistartDate"/>
        <result property="holiEndDate" column="holiendDate"/>
        <result property="holiName" column="holiname"/>       
        <result property="holiRemark" column="holiremark" nullValue=""/>
    </resultMap>
      </sql>
验证：
很简单在sql server里写一条sql 语句：select * from  T_holiday
执行后发现remark字段有的为空，O(∩_∩)O~，找到问题根结啦。
解决：
   <result property="holiRemark" column="holiremark" nullValue=""/>
完结！呵呵，只要报错，就能找到问题原因
