Hibernate是怎么工作的——Hibernate的工作流程

举个简单的例子说明：

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();
	}
}

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;
	}
}
