Question

我是ORM工具的新手。我试着学习NHibernate。我的代码块在下面。

这是员工的映射：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" auto-import="true"
assembly="NHiberanate" namespace="NHiberanate.Models">
  <class name="Employee" table="tblEmployee" dynamic-update="true" >
    <cache usage="read-write"/>
    <id name="Id" column="Id" type="int">
      <generator class="native" />
    </id>
    <property name="FirstName" />
    <property name="LastName" />
    <property name="Designation" />
  </class>
</hibernate-mapping>

和nhibernate配置：

<?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">
      Server=(local);database=MyTestDB;Integrated Security=SSPI;
    </property>
    <property name="dialect">
      NHibernate.Dialect.MsSql2012Dialect
    </property>
  </session-factory>
</hibernate-configuration>

我的会话课程：

using NHibernate;
using NHibernate.Cfg;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace NHiberanate.Models.NHibernate
{
    public class OpenNHibertnateSession
    {
        public static ISession OpenSession()
        {
            var configuration = new Configuration();
            var configurationPath = HttpContext.Current.Server.MapPath
            (@"~\Models\Nhibernate\nhibernate.configuration.xml");
            configuration.Configure(configurationPath);
            var employeeConfigurationFile = HttpContext.Current.Server.MapPath
            (@"~\Models\Nhibernate\Employee.mapping.xml");
            configuration.AddFile(employeeConfigurationFile);
            ISessionFactory sessionFactory = configuration.BuildSessionFactory();
            return sessionFactory.OpenSession();
        }
    }
}

和我的模特：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace NHiberanate.Models
{
    public class Employee
    {
        public virtual int? Id { get; set; }
        public virtual string FirstName { get; set; }
        public virtual string LastName { get; set; }
        public virtual string Designation { get; set; }
    }
}

在会话类中，此行有一个错误configuration.AddFile(employeeConfigurationFile);。它说＆＃34;无法编译映射文件＆＃34;。哪里弄错了？
