ibatis的配置：

  <resultMap id="App_ResultMap" class="com.alibaba.click.bean.App" >
    <result column="ID" property="id" jdbcType="INTEGER" />
    <result column="APPNAME" property="appname" jdbcType="VARCHAR" />
    <result column="USER_ID" property="userId" jdbcType="INTEGER" />
    <result column="STATUS" property="status" jdbcType="CHAR" />
    <result column="OWNER" property="owner" jdbcType="VARCHAR" />
    <result column="SYNC_TYPE" property="syncType" jdbcType="VARCHAR" />
    <result column="CREATE_TIME" property="createTime" />
    <result column="MODIFY_TIME" property="modifyTime" />
    <result column="LAST_SYNC_TIME" property="lastSyncTime" />
    <result column="USERNAME" property="userName" jdbcType="VARCHAR" />
    <result column="DW_CLICK_URL" property="dwClickUrl"  jdbcType="VARCHAR"/>
    <result column="DW_EXPOSURE_URL" property="dwExposureUrl" jdbcType="VARCHAR" />
  </resultMap>
  
  <!-- 查询 -->
  <select id="query" resultMap="App_ResultMap" parameterClass="java.util.Map" >
    select CK_APP.ID, CK_APP.APPNAME, CK_APP.USER_ID, CK_APP.STATUS, CK_APP.OWNER,
    	   CK_APP.CREATE_TIME, CK_APP.MODIFY_TIME, CK_APP.LAST_SYNC_TIME,
    	   wpf_user.USERNAME,CK_APP.DW_CLICK_URL,CK_APP.DW_EXPOSURE_URL
    from 
    	CK_APP, wpf_user
    where
    	<!--  wpf_user.USER_ID=#userId# AND -->
    	CK_APP.STATUS != '0' AND
    	CK_APP.USER_ID = wpf_user.USER_ID <!-- AND
    	CK_APP.ID in
    	<iterate open="(" close=")" conjunction="," property="appIdList">  
            #appIdList[]#
        </iterate>  -->
  </select>

这里query的select语句查询出来的少了一个resultmap的一个字段 <result column="SYNC_TYPE" property="syncType" jdbcType="VARCHAR" />，所以报列名无效，

 

在下面的两个类里面会对查询结果根据resultmap反射到对应的bean里进行处理，可以查看对应的源码进行深入了解：
