hibernate的第一个程序

#建表语句
create database hibernate;
use hibernate;
create table user(
id int primary key,
name varchar(30) not null default '',
des varchar(100) not null default '')charset utf8;

　User.hbn.xml数据表字段与javaBean的属性对应关系

　　javaBean类 User.java

package com.henau.demo1;
 
public class User {
	private int id;
	private String name;
	private String des;
	public User(){}
	public User(int id,String name,String des){
		this.id=id;
		this.name=name;
		this.des=des;
	}
 
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getDes() {
		return des;
	}
	public void setDes(String des) {
		this.des = des;
	}
}

　操作类Demo1.java向数据库中插入数据

package com.henau.demo1;
 
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.classic.Session;
 
public class Demo1 {
	static Configuration config;
	static{
		config=new Configuration();
		config.configure();//加载配置文件
 
	}
	public static void main(String[] args) {
		SessionFactory sf=config.buildSessionFactory();
		Session ss=sf.openSession();
		Transaction tx=ss.beginTransaction();//开启事务
		//实例化javaBean对象
		User user=new User();
		user.setName("张三");
		user.setDes("好人");
		ss.save(user);
		tx.commit();//提交事务
		ss.close();
	}
