举个简单的样例说明：

1.Base.java

package cn.flymouse.hibernate;

import java.util.Date;

import org.hibernate.Query;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.Transaction;

import org.hibernate.cfg.Configuration;

import cn.flymouse.hibernate.domain.User;

public class Base {

	public static void main(String[] args) {

		//读取并解析配置文档hibernate.cfg.xml文件

		Configuration cfg = new Configuration().configure();

		//读取并解析映射文件，以Configuration创建SessionFactory

		SessionFactory sf = cfg.buidSessionFactory();

		//创建session

		Session session = sf.openSession();

		//开启事务

		Transaction tx = session.beginTransaction();

		//持久化操作

		User user = new User();

		user.setBirthday(new Date());

		user.setName("name");

		session.save(user);

		//提交事务

		tx.commit();

		//关闭Session

		session.close();

		//关闭SessionFactory

		sf.close();

	}

}

2.User.java

package cn.flymouse.hibernate.domain;

import java.util.Date;

public class User {

	private int id;

	private String name;

	private Date birthday;

	public int getId() {

		return id;

	}

	pubilc String getName(){

		return name;

	}

	public Date getBirthday() {

		return birthday;

	}

	public void setId(int id) {

		this.id = id;

	}

	public void setName(String name) {

		this.name = name;

	}

	public void setBirthday(Date birthday) {

		this.birthday = birthday;

	}

}

3.User的映射文件User.hbm.xml（跟User类放同个文件夹）：

<?

xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC

	"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

	"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="cn.flymouse.hibernate.domain">

	<class name="User">

		<id name="id">

			<generator class="native" />

		</id>

		<property name="name" unique="false"/>

		<property name="birthday" />

	</class>

</hibernate-mapping>

4.hibernate的配置文件hibernate.cfg.xml（放在类路径下，即src文件夹下）：

<!DOCTYPE hibernate-configuration PUBLIC

	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

	"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

	<session-factory>

		<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

		<property name="connection.url">jdbc:mysql:///test</property>

		<property name="connection.username">root</property>

		<property name="connection.password">123456</property>

		<!-- 方言，用于生成SQL语句 -->

		<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

		<!-- 自己主动建表 -->

		<property name="hbm2ddl.auto">create</property>

		<property name="show_sql">true</property>

		<mapping resource="cn/flymouse/hibernate/domain/User.hbm.xml"/>

	</session-factory>

</hibernate-configuration>
