我有 2 个与 nhibernate 一起使用的数据库表和类结构,如下所示。
D B
C# poco 类如下。
客户类
public class Customer
{
public virtual int CustomerID { get; set; }
public virtual string CustomerName { get; set; }
public virtual string Title { get; set; }
public virtual string FirstName { get; set; }
public virtual string LastName { get; set; }
public virtual string Mobile { get; set; }
public virtual string Phone { get; set; }
public virtual string Email { get; set; }
public virtual Address BillingAddress { get; set; }
public virtual Address ShippingAddress { get; set; }
}
地址类
public class Address
{
public virtual int AddressID { get; set; }
public virtual string AddressLine { get; set; }
public virtual string City { get; set; }
public virtual string State { get; set; }
public virtual int ZIP { get; set; }
public virtual string Fax { get; set; }
public virtual string Country { get; set; }
}
映射文件
客户.hbm.xml
<class name="Customer" table="Customers">
<id name="CustomerID">
<generator class="native" />
</id>
<property name="CustomerName" length="100" />
<property name="Title" length="10" />
<property name="FirstName" length="60" />
<property name="LastName" length="60" />
<property name="Mobile" length="15" />
<property name="Phone" length="15" />
<property name="Email" length="100" />
<many-to-one name="BillingAddress" class="Address" />
<many-to-one name="ShippingAddress" class="Address" />
</class>
地址.hbm.xml
<class name="Address" table="Addresses">
<id name="AddressID">
<generator class="native" />
</id>
<property name="AddressLine" length="255" />
<property name="City" length="30" />
<property name="State" length="30" />
<property name="ZIP" />
<property name="Fax" length="15" />
<property name="country" length="50" />
</class>
我正在使用 nhibernate 会话创建数据库表。表创建良好。使用上述结构,如果我想保存指定了 2 个地址类型的客户,如何将 1 个客户保存到客户表和 2 个地址到地址表?请参阅以下示例代码。
Address b_address = new Address();
Address s_address = new Address();
Customer customer = new Customer();
b_address.addressLine = "No.23, New Road";
b_address.City = "Newyork";
// more data
s_address.addressLine = "No.54, Old Road";
// more data
customer.CustomerName = "David";
// more customer data
customer.BillingAddress = b_address;
customer.ShippingAddress = s_address;
//saving the session.
session.save(customer)
上面的代码只将数据插入到客户表中。我如何将这个插入数据同时插入到客户和地址表中?
