Nhibernate3.3.3sp1基础搭建测试

实体类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace NHibernateTest.Entity 
{
    public class Customer
    {
        public virtual int CustomerID { get; set; }
        public virtual string Version { get; set; }
        public virtual string FirstName { get; set; }
        public virtual string LastName { get; set; }
    }
}

映射XML（嵌入的资源）

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
  assembly="NHibernateTest" namespace="NHibernateTest.Entity">
  <class name=" NHibernateTest.Entity.Customer,NHibernateTest" table="Customer" lazy="false">
    <id name="CustomerID" column="CustomerID" type="int">
      <generator class="native" />
    </id>
    <property name="Version" column="Version" type="String" length="50"/>
    <property name="FirstName" column="FirstName" type="String" length="50"/>
    <property name="LastName" column="LastName" type="String" length="50" />
  </class>
</hibernate-mapping>

Session工厂

using NHibernate;
using NHibernate.Cfg;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace NHibernateTest
{
    public class NHibernateHelper

        public ISession GetSession()
        {
            return _sessionFactory.OpenSession();

sql（需建NHTest库）

    CustomerID int primary key identity(1,1) not null,
    [Version] varchar(50) not null,
    FirstName varchar(50) not null,

    )
    
    create Table [Order]
    (
    OrderID int primary key identity(1,1) not null,
    [Version] varchar(50) not null,
    OrderDate date not null,
    CustomerID int not null foreign key references [Customer](CustomerID)
    )
    
    create Table Product
    (
    ProductID int Primary key identity(1,1) not null,
    [Version] varchar(50),
    Name varchar(50),
    Cost varchar(50)
    )
    
    create Table OrderProduct
    (
    OrderID int not null foreign key references [Order](OrderID),
    ProductID int not null foreign key references [Product](ProductID)

    insert into Customer([Version],FirstName,LastName) values('1.0', 'sam', 'sir')
insert into [Order]([Version],OrderDate,CustomerID) values('1.0',GETDATE(),2)
insert into Product([Version],Name,Cost) values('1.0','黑莓','$30')
insert into OrderProduct values(2,3)
