NHibernate2.0小试

用到的表

Create table UserInfo

 (

    id int identity(1,1) not null primary key,

   userName varchar(50) not null,

   pwd varchar(50) not null,

  age int not null

)

DEMO项目结构:

DomainModel层

UserInfo.cs

using System;
namespace DomainModel
{
    public class UserInfo
    {

        public virtual int Id { get; set; }

        public virtual string UserName { set; get; }

        public virtual string Pwd { set; get; }

        public virtual int Age { set; get; }

    }
}

UserInfo.hbm.xml（设置生产操作为嵌入的资源）

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
   assembly="DomainModel" namespace="DomainModel">
  <class name ="DomainModel.UserInfo,DomainModel" table="UserInfo">
    <id name="Id" column="id" type="Int32">
      <generator class ="native"></generator>
    </id>
    <property name="UserName" column ="userName" type="String" length="50" not-null="true"/>
    <property name ="Pwd" column="pwd" type="String" length="50" not-null="true"/>
    <property name ="Age" column="age" type="Int32"  not-null="true"/>
  </class>
</hibernate-mapping>

DAL 层引入 

 Castle.Core.dll  

Castle.DynamicProxy2.dll 

 Iesi.Collections.dll   

 NHibernate.dll

NHibernateHelper.cs

using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
using NHibernate.Cfg;
namespace DAL
{
    public static class NHibernateHelper
    {
        private static readonly ISessionFactory sessionFactory;

        private static ISession session = null;

        static NHibernateHelper()
        {

            sessionFactory = new Configuration().Configure().BuildSessionFactory();
        }

        public static ISession GetCurrentSession()
        {
            if (session == null)
            {

                session = sessionFactory.OpenSession();
            }
            return session;
        }

        public static void CloseSessionFactory()
        {

            if (sessionFactory != null)
            {
                sessionFactory.Close();

            }

        }

    }
}

UserService.cs

using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
using DomainModel;
namespace DAL
{
    public class UserService
    { 

//根据ID  获得该用户
        public UserInfo GetUserInfoById(int id)
        {
            return NHibernateHelper.GetCurrentSession().Get<UserInfo>(id);
        }
    }
}

DALTest层

引入nunit.framework.dll

hibernate.cfg.xml(在该层的bin目录下)

<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory >
   <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
   <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
   <property name="connection.connection_string">Data Source=.\SQLEXPRESS;initial catalog=demodb;User Id=sa;Password=sa;</property>
   <property name="show_sql">true</property>
   <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
   <property name="use_outer_join">true</property>
   <mapping assembly="DomainModel" />
</session-factory>
</hibernate-configuration>

DALTest.cs(该类查看是否运行成功)

using System;
using System.Collections.Generic;
using System.Text;
using DomainModel;
using NUnit.Framework;
using DAL;

namespace DALTest
{
    [TestFixture]
   public class DALTestCase
    {
        public UserService userService = null;
        [SetUp]
        public void SetUp()
        {
            userService = new UserService();
        }

        [Test]
        public void TestMethod()
        { 

               //数据库中ID为1的用户名为zhang
            var userInfo = userService.GetUserInfoById(1);
            Assert.AreEqual(userInfo.UserName, "zhang");
        }
    }
}

控制台输出：

------ Test started: Assembly: DALTest.dll ------

NHibernate: SELECT userinfo0_.id as id0_0_, userinfo0_.userName as userName0_0_, userinfo0_.pwd as pwd0_0_, userinfo0_.age as age0_0_ FROM UserInfo userinfo0_ WHERE userinfo0_.id=@p0; @p0 = '1'

1 passed, 0 failed, 0 skipped, took 14.02 seconds (NUnit 2.4).

可以看出该断言成功  并且有sql语句打印出来 说明配置成功！
