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>
