首先介绍下我的开发环境是vs2010旗舰版,nhibernate采用的是3.0版本。
一、在mvc4项目中装载配置nhibernate的第一种方式是采用【hibernate.xml】的方式:首先看图
使用这种方式配置nhibernate的话,需要将hibernate.xml【属性】改为始终复制到输入目录或作为嵌入资源使用。
当然要使用nhibernate的化,需要在项目中引入hibernate.dll.
接下来我们来看下,在代码中如何来装载我们对nhibernate的配置:
public class NhibernateHelper { private ISessionFactory _sessionFactory; private static ISession _session = null; public NhibernateHelper() { _sessionFactory = GetSessionFactory(); } public ISessionFactory GetSessionFactory() { //加载文件的方式 Configuration cfg = new Configuration().Configure(AppDomain.CurrentDomain.BaseDirectory+"/hibernate.cfg.xml"); //Configuration cfg = new Configuration(); //cfg.AddAssembly(Assembly.GetExecutingAssembly()); HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();//NHProf工具 cfg.AddAssembly("BusinessDemo");//BusinessDemo指的是包含数据表的dll类库如:user.hbm.xml //cfg.AddAssembly(typeof(User).Assembly); //cfg.AddAssembly(typeof(Order).Assembly); return cfg.BuildSessionFactory(); } public ISession GetSession() { if (_session != null && _session.IsOpen) return _session; else { _session = _sessionFactory.OpenSession(); return _session; } } }
然后我们在mvc4 Controller里边就可以这样来做下测试:
public class CustomerController : Controller{ public ISession session { get { return new NhibernateHelper().GetSession(); } } public ActionResult Index() { Customer customer = this.session.Load<Customer>(2); var result = new Result(); using (ITransaction tx = this.session.BeginTransaction()) { try { this.session.Delete(customer); this.session.Flush(); tx.Commit(); result.success = true; result.msg = "删除成功!"; } catch (HibernateException) { tx.Rollback(); result.success = true; result.msg = "删除失败!"; } } return Json(result, JsonRequestBehavior.AllowGet); } }
二、接下来我们来看如何在么mvc项目中如何在web.config中配置nhibernate信息:直接上代码
<configSections> <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" requirePermission="false"/> </configSections> <connectionStrings> </connectionStrings> <appSettings> <add key="webpages:Version" value="2.0.0.0" /> <add key="PreserveLoginUrl" value="true" /> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> </appSettings> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider, NHibernate</property> <property name="connection.connection_string">Database=test;Data Source=localhost;User Id=root;Password=root</property> <property name="dialect">NHibernate.Dialect.MySQL5Dialect</property> <property name="connection.driver_class">NHibernate.Driver.MySqlDataDriver</property> <property name="proxyfactory.factory_class">NHibernate.Bytecode.DefaultProxyFactoryFactory,NHibernate</property> </session-factory> </hibernate-configuration>
注: <property name="dialect"> 、<property name="connection.driver_class">这两个属性一定要和链接的数据库保持一致,这里边我采用的是mysql数据库。
然后我们直接来看如何来装载它:
public class NhibernateHelper { private ISessionFactory _sessionFactory; private static ISession _session = null; public NhibernateHelper() { _sessionFactory = GetSessionFactory(); } public ISessionFactory GetSessionFactory() { //加载文件的方式 //Configuration cfg = new Configuration().Configure(AppDomain.CurrentDomain.BaseDirectory+"/hibernate.cfg.xml"); Configuration cfg = new Configuration(); cfg.AddAssembly(Assembly.GetExecutingAssembly()); HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();//NHProf工具 //cfg.AddAssembly("BusinessDemo"); //cfg.AddAssembly(typeof(User).Assembly); //cfg.AddAssembly(typeof(Order).Assembly); return cfg.BuildSessionFactory(); } public ISession GetSession() { if (_session != null && _session.IsOpen) return _session; else { _session = _sessionFactory.OpenSession(); return _session; } } }
