整个项目的结构图如下：

1、开发工具Microsoft Visual Studio2010、SQL Server2012

2、NHibernate版本为3.3.1

3、新建类库GaoJie.Domain，在该类库项目下新建两个文件夹Domain和Mapping。

编写Student类，该类在Domain文件夹下。代码如下：

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5  6 namespace GaoJie.Domain.Domain 7 { 8     /// 
 9     /// Student10     /// 
11     public class Student12     {13         /// 
14         /// Id15         /// 
16         public virtual Guid Id { set; get; }17 18         /// 
19         /// Name20         /// 
21         public virtual string Name { set; get; }22 23         /// 
24         /// Age25         /// 
26         public virtual int Age { set; get; }27     }28 }

 

编写映射文件Student.hbm.xml，将该文件的属性设置为，如图所示：

代码如下：

1 
       2  3 
      
        4  5   
       
         6  7     
        
          8       
          9     
        10 11     
        
         12       
         13     
        14 15     
        
         16       
         17     
        18 19   
       20 21 
      

 

4、新建类库GaoJie.Lib，新建文件夹lib，里面有如下文件Iesi.Collections.dll、

NHibernate.dll、nunit.framework.dll

5、新建类库GaoJie.Dao，添加StudentDao类和IStudentDao接口。

StudentDao代码如下：

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using GaoJie.Domain.Domain; 6 using NHibernate; 7 using NHibernate.Cfg; 8 using NHibernate.Linq; 9 10 namespace GaoJie.Dao11 {12     public class StudentDao:IStudentDao13     {14         #region fields15         private ISession session;16         private ISessionFactory sessionFactory;17         #endregion18 19         #region Constructor20         public StudentDao()21         {22             var cfg = new Configuration().Configure("Config/hibernate.cfg.xml");23 24             using (sessionFactory = cfg.BuildSessionFactory())25             {26             }            27         }28         #endregion29 30         #region Method31 32 33         public object Save(Student student)34         {35             using (session = sessionFactory.OpenSession())36             {37                 var id=session.Save(student);38                 session.Flush();39                 return id;40             }41         }42 43         public void Update(Student student)44         {45             using (session = sessionFactory.OpenSession())46             {47                 session.Update(student);48                 session.Flush();49             }               50         }51 52         public void Delete(Student student)53         {54             using (session = sessionFactory.OpenSession())55             {56                 session.Delete(student);57                 session.Flush();58             }59         }60 61         public Student Get(object id)62         {63             using (session = sessionFactory.OpenSession())64             {65                 return session.Get
      
       (id);66             }67         }68 69         public IList
       
         GetAll()70         {71             using (session=sessionFactory.OpenSession())72             {73                 return session.Query
        
         ().ToList();74             }75         }76 77         private bool IsSessionOpen()78         {79             bool isSessionOpen = false;80 81             if (!session.IsOpen)82             {83                 session = sessionFactory.OpenSession();84                 isSessionOpen = true;85             }86 87             return isSessionOpen;88         }89         #endregion90     }91 }
        
       
      

 

IStudentDao代码如下：

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using GaoJie.Domain.Domain; 6  7 namespace GaoJie.Dao 8 { 9     public interface IStudentDao10     {11         object Save(Student student);12 13         void Update(Student student);14 15         void Delete(Student student);16 17         Student Get(object id);18 19         IList
      
        GetAll();20     }21 }
      

 

编写hibernate.cfg.xml：该文件在GaoJie.Dao类库下的Config文件夹下，设置该文件的属性，如图所示：

代码如下：

1 
       2  3 
      
        4  5   
       
         6     
        
         NHibernate.Driver.SqlClientDriver
         7     
        
          8       Server=(local);initial catalog=NHibernateDemo;Integrated Security=SSPI 9     
        10     
        
         10
        11     
        
         true
        12     
        
         NHibernate.Dialect.MsSql2008Dialect
        13     
        
         60
        14     
        
         update
        15     
        
         true 1, false 0, yes 'Y', no 'N'
        16     
        17   
       18 19 
      

 

6、新建类库GaoJie.Test，添加引用

Iesi.Collections.dll、

NHibernate.dll、nunit.framework.dll

新建StudentTest类，编写代码：

1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using GaoJie.Domain.Domain; 6 using NHibernate; 7 using NHibernate.Cfg; 8 using NUnit.Framework; 9 using GaoJie.Dao;10 using GaoJie.Domain;11 12 13 namespace GaoJie.Test14 {15     [TestFixture]16     public class StudentTest17     {18         private IStudentDao studentDao; 19 20         [SetUp]21         public void Init()22         {23             studentDao=new StudentDao();24         }25 26         [Test]27         public void Save()28         {29             Student student=new Student()30                                 {31                                     Id =Guid.NewGuid(),32                                     Name = "张三",33                                     Age = 2234                                 };35 36             var id = studentDao.Save(student);37 38             Assert.NotNull(id);39         }40 41         [Test]42         public void Update()43         {44             int expected = 0;45             var student = studentDao.GetAll().FirstOrDefault();46             47             Assert.NotNull(student);48 49             student.Age = 43;50             expected = student.Age;51 52             studentDao.Update(student);53 54             Assert.AreEqual(expected,student.Age);55         }56 57         [Test]58         public void Delete()59         {60             var student = studentDao.GetAll().FirstOrDefault();61             var id = student.Id;62             Assert.NotNull(student);63 64             studentDao.Delete(student);65             Assert.Null(studentDao.Get(id));66         }67 68         [Test]69         public void Get()70         {71             var student = studentDao.GetAll().FirstOrDefault();72             Assert.NotNull(student);73 74             student=studentDao.Get(student.Id);75             Assert.NotNull(student);76         }77 78         [Test]79         public void GetAll()80         {81             var student = studentDao.GetAll().Count;82             Assert.NotNull(student>0);83         }84     }85 }

 

测试结果如下：
