Hello Stackoverflower。
当我试图从我的数据库中获取值时，我有这个例外。 据我所知，我必须设置一个not-found =＆＃34;忽略＆＃34;标记来解决这个问题。问题是这个标签只允许在多对一关系中使用，而异常则指向一个属性（查看映射）。我已经尝试过not-null Tag来解决它，但它给了我同样的异常。
我正在使用：
此属性的我的映射看起来像这样：
<property name="fkraceId" not-null="false" type="int">
<column name="fk_race_id" not-null="false" />
</property>
我收到以下例外情况。我感谢每一个提示或解决方案。
