SSH框架-Caused by: org.hibernate.MappingException: column attribute may not be used together with <column> subelement

昨晚修改了一些表关系，在相关的hbm.xml文件中做了改动，今天早上起来启动tomcat后，发现项目启动不了，控制台报错：

 为了解决这个问题，我又把昨晚改动过的hbm.xml文件恢复为原来的，再次启动发现没有报错，问题已经确定：hbm.xml文件配置问题。

看这个报错信息，应该是某个property属性的字段配置错了，于是我改过hbm.xml的文件一个个去核对，发现有一个XX.hbm.xml文件里面果然配置错了

如下：

        <!-- 用户表 ，多对一映射-->
        <many-to-one name="User" class="cn.test.web.pojo.User" column="user_id">
           <column name="user_id"></column>
        </many-to-one>

因为在配置many-to-one标签时，在 <many-to-one >标签这里既有column属性，也有column元素，明显是重复了，只需要配置一个colum即可！我把<column></column>去掉后，再重启tomcat，没有报错，问题解决！
