找了好长时间终于找到问题所在：

     由于我的UserMapper.xml在配置的时候，

<mapper namespace="com.lf.dao.UserMapper" >   <resultMap id="BaseResultMap" type="com.lf.pojo.User">

    User.java类中出现了User属性，错误的配置是：

<result column="create_by" property="createBy" jdbcType="VARCHAR"/>

 正确的配置应该是：

<result column="create_by" property="createBy.id" jdbcType="VARCHAR"/>

因此引起了上述问题；

写程序还的细心仔细，谨记。。。。。。。
