NHibernate.MappingException：表表中的关联引用了未映射的类：Int32

Question

我开始使用Nhibernate并设法让一些示例正常工作，但现在，当Nhibernate加载配置时，应用程序就会抛出这个例子。

NHibernate.MappingException: An association from the table TBL_MARCADAS refers to an unmapped class: Int32
at NHibernate.Cfg.Configuration.SecondPassCompileForeignKeys(Table table, ISet done)
at NHibernate.Cfg.Configuration.SecondPassCompile()

好吧，我发现了问题。

我不知道为什么自动生成工具使用了多对一键：

<composite-id class="TblMarcadas">
      <key-many-to-one name="Codgestion" column="CODGESTION" />
      <key-many-to-one name="Codperiodo" column="CODPERIODO" />
      <key-many-to-one name="Coddiamarcada" column="CODDIAMARCADA" />
      <key-many-to-one name="Codempleado" column="CODEMPLEADO" />
    </composite-id>

我刚刚将其更改为key-property。

也许是因为这张桌子上有外键？

任何希望这有助于一个人再见
