Nhibernate教程2(2)

3. 创建.Net类和与其对应的XML文件

 

(1)       单表的情况

 

单表的情况就是指该表没有和其他表有关联的情况。这样情况下,可以用软件来辅助产生类和对应的XML文件。在这里,仍然采用手写的方式来生成这两个文件。对于课程表,需要写的类和XML如下所示:

 


类文件(Course.cs

 

using System;

 

namespace NHibernateTest{

 

         public class Course{

 

                   public Course(){}

 

                   private int courseId;

 

                   private string courseName;

 

           private DateTime dateCreated;

 

                   public int CourseId{

 

                            get { return courseId; }

 

                            set { courseId = value; }

 

                   }

 

                   public string CourseName{

 

                            get { return courseName; }

 

                            set { courseName = value; }

 

                   }

 

                   public DateTime DateCreated{

 

                            get { return dateCreated; }

 

                            set { dateCreated = value; }

 

                   }                

 

         }

 

}

 

XML文件(Course.hbm.xml

 

<?xml version="1.0" encoding="utf-8" ?>

 

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">

 

         <class name="NHibernateTest.Course, NHibernateTest" table="Course">

 

                   <id name="CourseId" column="CourseId" type="Int32">

 

                            <generator class="native" />

 

                   </id>

 

                   <property name="CourseName" column= "CourseName" type="string" length="40"/>                 

 

                   <property name="DateCreated" type="DateTime" length="8"/>

 

         </class>

 

</hibernate-mapping>
