白广元写的java web整合开发完全自学手册的源代码

package hibernate3;

import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

import hibernate3.object.Person;

public class FirstHibernate {
	
	
	public static void main(String[] args) {
		// Configuration 負責管理 Hibernate配置訊息
		Configuration config = new Configuration().configure();

		// 根据config建立SessionFactory
		// SessionFactory将用于建立Session
		SessionFactory sessionFactory = config.buildSessionFactory();

		// 将持久化的物件
		Person person = new Person();
		person.setId(55);
		person.setName("neo");
		person.setAge(13);
		// 开启Session，相当于开启JDBC的Connection
		Session session = sessionFactory.openSession();
		// Transaction表示一组对DB的交易
		Transaction tx = session.beginTransaction();

		System.out.println("新增人员成功!");

		// 读取主键（id）为1的人员信息
		Person p = (Person) session.get(Person.class, 31);
		System.out.println(p);
		session.update(person);
        session.flush();
	    tx.commit();
		session.close();
		sessionFactory.close();
