Hibernate Hello World

今天开始学习Hibernate3.3.2，虽然之前或多或少的接触到过一点Hibernate的知识，但是这又能说明什么问题呢？什么都不能说明，将自己调试的helloworld程序贴上来，希望和大家一起分享，共同进步。
数据库：mysql
sql语句：
create database hibernate;
use hibernate;
create table student(
id int primary key auto_increment,
name varchar(20),
age int
);

student.java

package com.model;

public class student {
	private int id;
	private int age;
	private String name;
	
	/**
	 * @return the id
	 */
	public int getId() {
		return id;
	}
	/**
	 * @param id the id to set
	 */
	public void setId(int id) {
		this.id = id;
	}
	/**
	 * @return the age
	 */
	public int getAge() {
		return age;
	}
	/**
	 * @param age the age to set
	 */
	public void setAge(int age) {
		this.age = age;
	}
	/**
	 * @return the name
	 */
	public String getName() {
		return name;
	}
	/**
	 * @param name the name to set
	 */
	public void setName(String name) {
		this.name = name;
	}
	
	
}

student.hbm.xml

<?xml version="1.0"?>

	<class name="com.model.student">

    </class>
	
</hibernate-mapping>

StudentTest.java

package com.model.test;


import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.classic.Session;

import com.model.student;

public class StudentTest {
	public static void main(String[] args){
		student stu = new student();
//		stu.setId(4);
		stu.setAge(10);
		stu.setName("li");
		
		Configuration conf = new Configuration();
		SessionFactory sf = conf.configure().buildSessionFactory();
		Session sess = sf.openSession();
		sess.beginTransaction();
		sess.save(stu);
		sess.getTransaction().commit();
		sess.close();
		sf.close();
		
	}
}

hibernate.cfg.xml存放于src根目录下
