我最近通过 NuGet 从 1.3.0.717 和 3.2.0.4000 版本将我的项目更新为 FNH 1.3.0.727 和 NH 3.3.0.4000。使用 automap，更新前生成的 XML 如下所示：

  <class xmlns="urn:nhibernate-mapping-2.2" name="APP.Domain.Module, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="Module">
    <id name="Id" type="System.Guid, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="ModuleId" />
      <generator class="guid.comb" />
    </id>
    <many-to-one class="APP.Domain.Product, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Product">
      <column name="ProductId" />
    </many-to-one>
    <joined-subclass name="APP.Domain.Audit.Trail, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
      <key>
        <column name="TrailId" />
      </key>
      <bag cascade="all" inverse="true" lazy="true" name="Arguments">
        <key>
          <column name="TrailId" />
        </key>
        <one-to-many class="APP.Domain.Audit.Argument, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
      </bag>
      <property name="Action" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="Action" />
      </property>
      <property name="Date" type="System.DateTime, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="Date" />
      </property>
      <property name="Workflow" type="System.Boolean, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="Workflow" />
      </property>
      <property name="Identity" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="[Identity]" />
      </property>
    </joined-subclass>
  </class>

更新后：

  <class xmlns="urn:nhibernate-mapping-2.2" name="APP.Domain.Module, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="`Module`">
    <id name="Id" type="System.Guid, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <column name="ModuleId" />
      <generator class="guid.comb" />
    </id>
    <many-to-one class="APP.Domain.Product, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Product">
      <column name="ProductId" />
    </many-to-one>
    <joined-subclass name="APP.Domain.Audit.Trail, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
      <key>
        <column name="TrailId" />
        <column name="ModuleId" />
      </key>
      <bag cascade="all" inverse="true" lazy="true" name="Arguments">
        <key>
          <column name="TrailId" />
          <column name="TrailId" />
        </key>
        <one-to-many class="APP.Domain.Audit.Argument, APP.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
      </bag>
      <property name="Name" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="Name" />
      </property>
      <property name="Date" type="System.DateTime, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="Date" />
      </property>
      <property name="Workflow" type="System.Boolean, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="Workflow" />
      </property>
      <property name="Identity" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
        <column name="[Identity]" />
      </property>
    </joined-subclass>
  </class>

我的模型中没有复合键，一切正常，现在我开始异常了"Foreign key (FK4B9386BFF4D27734:Argument [TrailId])) must have same number of columns as the referenced primary key (Trail [TrailId, ModuleId])"。

我错过了新版本的一些东西吗？

问题在于约定和覆盖的组合。以前的版本在每种情况下都正确地覆盖了键列（foreign、joined、hasmany、manytomany 等），但现在正在添加它们。漏洞？

使用 IReferenceConvention 代替在 ForeignKeyconvention 类中覆盖 GetKeyName 解决了该问题。
