    写在前面

    一年前刚来这家公司,发现项目中使用的ORM是Nhibernate,这个之前确实没接触过,EF多少在项目中用过,想着既然都是ORM,应该语法上都差不多。当时也就是硬着头皮上的,刚开始也只能通过模仿别人的代码,再加上自己的理解,一些增删改查的方法,确实也被自己给搞出来了,现在回头想想,在项目中,用到的那些方法基本上就一个样,很少有变化。除非有些业务逻辑非常强的,自己搞不定,问一下同事,还是可以解决的。到现在使用Nhibernate也很长时间,中间多少也查过一些资料,从网上下的nhibernate文档.docx,但是每次想去找的时候,总的在电脑上去找,比较麻烦,就干脆记录在博客中了,当时就是有哪些不明白的,可以很方便的从里面查,比如参数是什么含义。也总结了一些,在使用过程遇到的问题。

    现在项目告一段落,坐等为客户去部署了,也就有那么点空闲时间,那就要系统的学习一下了。

    发现在写这篇文章的时候,说了自己的一些学习方式,发现越写越多,就单独成篇了,也就有了这篇文章——如何高效的利用博客园?

    上篇文章,也算是nhibernate学习的开篇吧。

    搭建项目

    项目结构和映射文件

     

    项目结构说明

    采用传统三层架构

    Wolfy.Shop.Domain:数据实体和数据库映射文件。也有人叫做领域层。

    Wolfy.Shop.Data:数据层,存放数据库的操作及Nhibernate辅助类。引用Iesi.Collections.dll,NHibernate.dll和类库Wolfy.Shop.Domain

    Wolfy.Shop.Business:业务逻辑类。引用类库项目Wolfy.Shop.Domain,Wolfy.Shop.Data

    Wolfy.Shop.WebSite:测试项目。需引用Iesi.Collections.dll,NHibernate.dll和类库项目Wolfy.Shop.Domain,Wolfy.Shop.Business

    Nhibernate最新版本为4.0.1.GA,下载地址:http://nhforge.org/

    解压NHibernate-4.0.1.GA-bin.zip压缩包,内容如下:

    其中Confiuration_Templates文件夹内包括:

    这些xml内为数据库连接配置文件模版,通过上图也可以发现nhibernate支持的数据库种类还是很全的。主流的数据库已经都包括在内了。

    那么,咱们打开MSSQL.cfg的文件看一下

     1 <?xml version="1.0" encoding="utf-8"?>
     2 <!-- 
     3 This template was written to work with NHibernate.Test.
     4 Copy the template to your NHibernate.Test project folder and rename it in hibernate.cfg.xml and change it 
     5 for your own use before compile tests in VisualStudio.
     6 -->
     7 <!-- This is the System.Data.dll provider for SQL Server -->
     8 <hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >
     9     <session-factory name="NHibernate.Test">
    10         <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    11         <property name="connection.connection_string">
    12             Server=(local);initial catalog=nhibernate;Integrated Security=SSPI
    13         </property>
    14         <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
    15     </session-factory>
    16 </hibernate-configuration>

    通过上面的注释部分咱们可以得到一个信息,就是在项目中使用的话,需要将文件重命名为hibernate.cfg.xml.

    添加引用

    同样可以通过Nuget进行添加,如图:

    持久化类

    为客户实体创建持久化类

     1 namespace Wolfy.Shop.Domain.Entities
     2 {
     3     /// <summary>
     4     /// 描述:客户实体,数据库持久化类
     5     /// 创建人:wolfy
     6     /// 创建时间:2014-10-16
     7     /// </summary>
     8     public class Customer
     9     {
    10         /// <summary>
    11         /// 客户id
    12         /// </summary>
    13         public virtual Guid CustomerID { get; set; }
    14         /// <summary>
    15         /// 客户名字
    16         /// </summary>
    17         public virtual string CustomerName { get; set; }
    18         /// <summary>
    19         /// 客户地址
    20         /// </summary>
    21         public virtual string CustomerAddress { get; set; }
    22     }
    23 }
    注意NHibernate默认使用代理功能,要求持久化类不是sealed的,而且其公共方法、属性和事件声明为virtual。在这里,类中的字段要设置为virtual,否则出现“

    “NHibernate.InvalidProxyTypeException”类型的异常在 Wolfy.Shop.Data.dll 中发生,但未在用户代码中进行处理

    其他信息: The following types may not be used as proxies:

    Wolfy.Shop.Domain.Entities.Customer: method get_CustomerID should be 'public/protected virtual' or 'protected internal virtual'

    Wolfy.Shop.Domain.Entities.Customer: method set_CustomerID should be 'public/protected virtual' or 'protected internal virtual'

    Wolfy.Shop.Domain.Entities.Customer: method get_CustomerName should be 'public/protected virtual' or 'protected internal virtual'

    Wolfy.Shop.Domain.Entities.Customer: method set_CustomerName should be 'public/protected virtual' or 'protected internal virtual'

    ”异常。

    编写映射文件

    编写NHibernate配置文件智能提示的功能。只要在下载的NHibernate里找到configuration.xsd和nhibernate-mapping.xsd两个文件并复制到vs安装目录下,如C:Program  FilesMicrosoft Visual Studio 9.0XmlSchemas目录即可。

    此时,你在nhibernate的配置文件中就有智能提示功能了。

    nhibernate如何知道持久化类和数据库表的对应关系的呢?这就要通过映射文件来完成这个任务了,映射文件包含了对象/关系映射所需的元数据。元数据包含持久化类的声明和属性到数据库的映射。映射文件告诉nhibernate它应该访问数据库里面的哪个表及使用表里面的哪些字段。

    那么我们编写Customer持久化类的映射文件,注意映射文件以.hbm.xml结尾。如Customer.hbm.xml

     1 <?xml version="1.0" encoding="utf-8" ?>
     2 <!--assembly:程序集,namespace:命名空间-->
     3 <hibernate-mapping  xmlns="urn:nhibernate-mapping-2.2" assembly="Wolfy.Shop.Domain"  namespace="Wolfy.Shop.Domain.Entities">
     4   <class name="Wolfy.Shop.Domain.Entities.Customer,Wolfy.Shop.Domain" table="TB_Customer">
     5     <!--主键-->
     6     <id name="CustomerID" type="Guid" unsaved-value="null">
     7       <column name="CustomerID" sql-type="uniqueidentifier" not-null="true" unique="true"/>
     8       <generator class="assigned"></generator>
     9     </id>
    10     <property name="CustomerName" type="String">
    11       <column name="CustomerName" sql-type="nvarchar"  not-null="false"/>
    12     </property>
    13      <property name="CustomerAddress" type="String">
    14       <column name="CustomerAddress" sql-type="nvarchar"  not-null="false"/>
    15     </property>
    16    
    17   </class>
    18 </hibernate-mapping>

    这些东西该怎么记?记住根节点hibernate,并且映射文件中要有主键id和property节点就可以了,其他的依赖vs的智能提示,就可以了。
    这里需要养成一个习惯,就写好映射文件,需要修改它的属性

    否则会出现,如下错误,而这个错误也是使用nhibernate最常见,所以养成一个好习惯,能提高你的开发效率:

    辅助类

    在使用之前,需要通过ISessionFactory获得ISession,ISessionFactory的详细介绍可以参考文档[NHibernate]ISessionFactory配置 ,ISessionFactory是线程安全的,而ISession是非线程安全的。很多线程可以同时访问ISessionFactory,所以ISession要通过ISessionFactory打开,在所有的工作完成后,需要关闭。ISessionFactory通常是个线程安全的全局对象,只需要被实例化一次(可以使用单例模式)。这里编写一个简单的辅助类NHibernateHelper,用于创建ISessionFactory和配置ISessionFactory,并打开一个新的ISession的方法。代码如下:

     1 using NHibernate;
     2 using NHibernate.Cfg;
     3 using System;
     4 using System.Collections.Generic;
     5 using System.Linq;
     6 using System.Text;
     7 using System.Threading.Tasks;
     8 
     9 namespace Wolfy.Shop.Data
    10 {
    11     /// <summary>
    12     /// 描述:nhibernate辅助类
    13     /// 创建人:wolfy
    14     /// 创建时间:2014-10-16
    15     /// </summary>
    16     public class NHibernateHelper
    17     {
    18         private ISessionFactory _sessionFactory;
    19         public NHibernateHelper()
    20         {
    21             //创建ISessionFactory
    22             _sessionFactory = GetSessionFactory();
    23         }
    24         /// <summary>
    25         /// 创建ISessionFactory
    26         /// </summary>
    27         /// <returns></returns>
    28         public ISessionFactory GetSessionFactory()
    29         {
    30             //配置ISessionFactory
    31             return (new Configuration()).Configure().BuildSessionFactory();
    32         }
    33         /// <summary>
    34         /// 打开ISession
    35         /// </summary>
    36         /// <returns></returns>
    37         public ISession GetSession()
    38         {
    39             return _sessionFactory.OpenSession();
    40         }
    41     }
    42 
    43 }
    View Code

    这里需引入命名空间:NHibernate和NHibernate.Cfg。

    数据库设计与连接配置

    nhibernate配置,也就是数据库配置:

    这里使用的是SQL Server2012,所以我们使用MSSQL.cfg.xml文件,重命名为hibernate.cfg.xml.

    注意需根据自己数据库的实例名修改,并添加mapping节点,其他的设置,可根据需要进行添加。这里采用最简单的一种方式,关于nhibernate的配置参数,可参考文档中的说明。

     1  1 <?xml version="1.0" encoding="utf-8" ?>
     2  2 <hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >
     3  3   <session-factory>
     4  4     <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
     5  5     <property name="connection.connection_string">
     6  6       server=.;database=shop;uid=sa;pwd=sa
     7  7     </property>
     8  8     <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
     9  9     <mapping  assembly="Wolfy.Shop.Domain"/>
    10 10   </session-factory>
    11 11 </hibernate-configuration>

    修改后,将hibernate.cfg.xml拷入Wolfy.Shop.WebSite项目,并修改其属性:

    否则会出现如下异常:

    界面

    通过SQL Server Profiler查看生成的sql语句

    通过监控到的sql语句,也可以看到使用nhibernate插入数据时,数据库中是通过存储过程进行插入数据的。

    总结

    本文简单介绍了使用nhibernate的一些配置,给我的感觉是,在使用时只要配置正确,其他的增删改查什么的也就没什么难的了。在配置nhibernate的时候,有些细节需要注意。比如映射文件和nhibernate的配置文件的属性需要进行修改。
