* 请看上面多对一的地方↑↑↑
* 注解配置解决方法：
*使用hibernate 注解配置实体类的关联关系，在many-to-one,one-to-one关联中，一边引用自另一边的属性，如果属性值为某某的数据在数据库不存在了，hibernate默认会抛出异常。解决此问题，加上如下注解就可以了：
*@NotFound(action=NotFoundAction.IGNORE)，意思是找不到引用的外键数据时忽略，NotFound默认是exception

产生此问题的原因在此记录下来:
有两张表,table1和table2. 产生此问题的原因就是table1里做了关联<one-to-one>或者<many-to-one unique="true">(特殊的多对一映射,实际就是一对一)来关联table2.当hibernate查找的时候,table2里的数据没 有与table1相匹配的,这样就会报No row with the given identifier exists这个错.(一句话,就是数据的现在hibernate配置可以基于xml配置文件和注解方式，这两种方式都能发生这个异常
以下是XML 配置形式的加法：
<many-to-one class="com.art.model.user.UserInfo" fetch="join" name="userInfo" > <column name="userId" unique="true"/> </many-to-one>
<many-to-one class="com.art.model.user.UserInfo" fetch="join" name="userInfo" not-found="ignore"> <column name="userId" unique="true"/> </many-to-one>
