Nhibernate一對一關系映射概述

現有兩個表：user(用戶)和Blog(設置表)，它們之間的關系正如我所說的是一對一的關系。現在我們來映射這兩個文件：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
  namespace="MyMvc4Project.Models" assembly="MyMvc4Project.Models">
    <class name="MyMvc4Project.Models.User" table="Users" lazy="false">
        <id name="Id">
            <column name="Id" sql-type="varchar(40)" not-null="true"/>
            <generator class="uuid.hex" />
        </id>
        <one-to-one name="Blog" class="Blog" cascade="all"></one-to-one>
    </class>
</hibernate-mapping>
    
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
  namespace="MyMvc4Project.Models" assembly="MyMvc4Project.Models">
    <class name="MyMvc4Project.Models.Blog" table="Blog" lazy="false">
        <id name="Id">
            <column name="Id" sql-type="varchar(40)" not-null="true"/>
            <generator class="foreign">
                <param name="property">User</param>
            </generator>
        </id>
        <one-to-one name="User" class="User" constrained="true"></one-to-one>
    </class>
</hibernate-mapping>

現在測試如何保存數據：

var userDal = new UserDal();
var blogDal = new BlogDal();
var user = new User{
                       Name = name,
                       Password = password,
                       PostTitle = posttitle,
                       CreateTime = DateTime.Now,
                       Avatar = fileUrl
                   };
var blog = new Blog { User = user };
    
user.Blog = blog;
blogDal.Save(blog);
userDal.Save(user);
