NHibernate - 一对一映射

Question

我在Person类和Employee之间有一对一的关系。我期望INSERT从人员级联到员工级联。但是，这不会发生。我已经在一对一的关系元素上尝试了cascade ='all'和cascade ='save-update'，但它不起作用。我还上传到我的整个源代码：http://bit.ly/gnkxBr（3.52 MB）

的我的对象的结构是如下所示：下面所示

public class Person 
{ 
    public virtual Employee Employee { get; set; } 
    public virtual int Age { get; set; } 
    public virtual string Forename { get; set; } 
    public virtual string Surname { get; set; } 
    public virtual int PersonID { get; set; } 
} 

public class Employee 
{ 
    public virtual int PersonID { get; set; } 
    public virtual string PayRollNo { get; set; } 
    public virtual int Holidays { get; set; } 
    public virtual Person Person { get; set; } 
} 

映射文件：

<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> 
    <class name="Person, Employee.DAL" table="`Person`" > 
    <id name="PersonID" column="`PersonId`" type="int"> 
     <generator class="native" /> 
    </id> 
    <property type="string" name="Forename" column="`Forename`" /> 
    <property type="string" name="Surname" column="`Surname`" /> 
    <property type="int" name="Age" column="`Age`" /> 
    <one-to-one name="Employee" class="Employee" cascade="all" /> 
    </class> 
</hibernate-mapping> 


<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> 
    <class name="Employee, Employee.DAL" table="`Employee`" > 
    <id name="PersonID" column="`PersonId`"> 
     <generator class="foreign"> 
     <param name="property" >Person</param> 
     </generator> 
    </id> 
    <property type="string" length="30" name="PayRollNo" column="`PayRollNo`" /> 
    <property type="int" name="Holidays" column="`Holidays`" /> 
    <one-to-one name="Person" class="Person" constrained="true" /> 
    </class> 
</hibernate-mapping> 

Answer 1

把事务中的session.Save（）方法。或者在调用save方法后使用session.Flush（）方法。
