NHibernate：存储过程和组件

我将一个存储过程作为NamedQuery调用，它正在工作 好的 当我尝试加载一个组件时，问题就开始了。 存储过程返回如下所示的记录集

[IdeEmployee，EmployeeName，城市，国家]

其中IDEEmployee和EmployeeName属于映射实体，城市和国家/地区来自组件

下面是映射：

<class name="Employee" table="employees"> 
    <id name="IDEmployee"> 
      <column name="idemployee" /> 
      <generator class="native" /> 
    </id> 
    <property name="EmployeeName "> 
      <column name="employeename" /> 
    </property> 
    <component name="Address" class="Address"> 
      <property name="City"> 
        <column name="city" /> 
      </property> 
      <property name="Country"> 
        <column name="country" /> 
      </property> 
    </component> 
  </class> 

如果我从地图上删除该组件，一切正常。 我还尝试了带有嵌套返回列的return属性，但没有成功

有小费吗？谢谢大家!

我最近不得不面对这个问题，这是我可以出来的方式

<sql-query name="GetEmployeesByCompany">
  <return class="Employee">
    <return-property column="idemployee" name="IDEmployee" />
    <return-property column="employeename" name="EmployeeName" /> 
    <return-property name="Address">  <!-- name of the component -->
      <return-column name="city" />  <!-- name of the resultset field -->
      <return-column name="country" />  <!-- name of the resultset field -->
    </return-property>
</return> 
EXEC GetEmployeeByCompany:idcompany 

执行官GetEmployeeByCompany:idcompany

return属性中字段的使用顺序非常重要，它必须与resultset中的顺序匹配。周围没有任何文档，我希望这可以帮助您

作为旁注。。而且可能太晚了。。你看过iBatis而不是NHibernate吗？它更侧重于使用存储过程。这是一个宝贵的建议，我将在未来尝试！

 var result = 
    session<ISession>().GetNamedQuery("GetEmployeesByCompany") 
                .SetInt32("idcompany", companyId) 
                .List<Employee>().ToList();
