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>
