第一炮：重叙hibernate入门示例-www.hibernate.org.cn中有一例子，但是感觉不是很清楚，主要是给初级兄弟看

三.hibernate.cfg.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration
    PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

<hibernate-configuration>
 <session-factory>
  <!-- local connection properties -->
  <property name="hibernate.connection.url">
   jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=test;SelectMethod=cursor
  </property>
  <property name="hibernate.connection.driver_class">
   com.microsoft.jdbc.sqlserver.SQLServerDriver
  </property>
  <property name="hibernate.connection.username">sa</property>
  <property name="hibernate.connection.password">scroll</property>
  <!-- property name="hibernate.connection.pool_size"></property -->
  <!-- dialect for Microsoft SQL Server -->
  <property name="dialect">
   net.sf.hibernate.dialect.SQLServerDialect
  </property>
  <property name="hibernate.show_sql">true</property>
  <property name="hibernate.use_outer_join">true</property>
  <!--
   property name="hibernate.transaction.factory_class">net.sf.hibernate.transaction.JTATransactionFactory</property>
   <property name="jta.UserTransaction">java:comp/UserTransaction</property
  //-->
  <mapping resource="com/tjlog/po/Person.hbm" /> 
  <mapping resource="com/tjlog/po/Author.hbm" />
 </session-factory>
</hibernate-configuration>
注意：我把  <!--   property name="hibernate.transaction.factory_class">net.sf.hibernate.transaction.JTATransactionFactory</property>
   <property name="jta.UserTransaction">java:comp/UserTransaction</property  //--> 注释了，因为我是直接使用JDBC的，如果不注释就报错！

四.person.hbm
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
 "-//Hibernate/Hibernate Mapping DTD//EN"
 "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

<hibernate-mapping package="com.tjlog.po">
 <class
  name="Person"
  table="PERSON"
 >
  <id
   name="Id"
   type="java.lang.Integer"
   column="Person_Id"
  >
      <generator class="identity" />
   
  </id>

  <property
   name="Email"
   column="Email"
   type="string"
   not-null="false"
   length="100"
  />
  <property
   name="Name"
   column="Name"
   type="string"
   not-null="false"
   length="100"
   
  />

 </class>
</hibernate-mapping>

五.author.hbm
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
 "-//Hibernate/Hibernate Mapping DTD//EN"
 "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

<hibernate-mapping package="com.tjlog.po">
 <class name="Author" table="AUTHOR">
  <id
   column="Author_Id"
   name="Id"
   type="java.lang.Integer"
  >
   <generator class="identity" />
  </id>
  <property
   column="Alias"
   length="100"
   name="Alias"
   not-null="false"
   type="string"
   />
  <many-to-one
   cascade="all"
   class="com.tjlog.po.Person"
   column="Person_Id"
   name="person"
   not-null="true"
   outer-join="auto"
   />
 </class>
</hibernate-mapping>

六.测试类 CommonExample （其实可以使用 HibernateUtil.java  的，仅测试，如果需要在实际使用，则就需要DAO封装）
/*
 * 创建日期 2005-1-24
 *
 */
package com.tjlog.example;

/**
 * @author Administrator
 * @CorpRight DongYiPing
 */
import net.sf.hibernate.*;
import net.sf.hibernate.cfg.*;
import java.util.*;

import com.tjlog.po.*;

public class CommonExample
{
 public CommonExample()
 {}
 public static void main(String[] args)
 
 {
  List list; 
  
    try {
     Configuration cfg = new Configuration().configure();
     SessionFactory sessions = cfg.buildSessionFactory();
     Session session = sessions.openSession();
     Transaction tx = session.beginTransaction();
    
     Person person = new Person();
       
  person.setName("DongYiPing");
  person.setEmail([email protected]);
       
  Author author = new Author();

  author.setAlias("pingping");
  author.setPerson(author);

    
    session.saveOrUpdate(person);
   
     tx.commit();
    session.close();
   } catch (Exception e) {
    System.out.println(e);
   }
 }
}
