－－－－－原因
JDK的XML解析兼容性不好。有些XML文件格式不太正规。。
在节点中加了注释。造成的这种问题。

－－－－定位出错的XML

下载MYBATIS的源码，附加上去调试。定位了出错的XML文件。。
然后把此文件一半XML代码删除，再试，直到这样二分查找试出出错的节点。。

我的原因是这样的

	<select id="dao-t_wl_logistics_d.queryforChild"
        parameterType="hashmap" resultType="flexmap">
        select logistics_scheme_no ,<!-- 物流方案号 -->
        node_no ,<!-- 节点号 -->
        logistics_act_code ,<!-- 活动类型代码 -->
        logistics_act_name,<!-- 活动类型名称 -->
        trnp_mode_code_21 ,
        trnp_mode_name_21,
        base_place_code,
        base_place_name ,
        delivery_place_code ,
        delivery_place_name

</select>
