生成一张表
User类

package com.anryn;
public class User {

	private int id ;
	private String useName ;
	
	private Date date ;

    public User() {
	}
	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getUseName() {
		return useName;
	}

	public void setUseName(String useName) {
		this.useName = useName;
	}

	public Date getDate() {
		return date;
	}

	public void setDate(Date date) {
		this.date = date;
	}
}

工具类：

package com.anryn;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            return new Configuration().configure().buildSessionFactory();
        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

User.hbm.xml配置文件：

<?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="com.anryn">
<class name="User" table="_User">
	<id name="id">
        <generator class="native"/>
    </id>
    <property name="useName"/>
    <property name="date"/>
</class>

</hibernate-mapping>

测试代码：

package com.anryn;
import java.util.Date;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class UserTest {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		User user = new User() ;
		
		user.setUseName("anryn") ;
		user.setDate(new Date()) ;
		
		//getSession
		SessionFactory sf = HibernateUtil.getSessionFactory() ;
		Session session = sf.getCurrentSession() ;
		
		session.beginTransaction() ;
		session.save(user) ;
		session.getTransaction().commit() ;
		
		sf.close() ;
	}
}
