Hibernate系列（一）：简单的数据插入

第一步，我们需要写一个POJO类：User.java

package cn.itcast.hibernate.domain;

import java.util.Date;

public class User {
	private int id;
	private String name;
	private Date birthday;
	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 Date getBirthday() {
		return birthday;
	}
	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}
	
	
}

<?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="cn.itcast.hibernate.domain">

	<class name="User" table="tb_User">
		<id name="id">
			<generator class="native"/> 
		</id>
		<property name="name" />
		<property name="birthday" />
	</class>
	
</hibernate-mapping>

<?xml version='1.0' encoding='utf-8'?> 
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
	<session-factory>
		<property name="connection.driver_class">
			com.mysql.jdbc.Driver

			org.hibernate.dialect.MySQLDialect
		</property>
		<mapping resource="cn/itcast/hibernate/domain/User.hbm.xml" />
	</session-factory>
</hibernate-configuration>

package cn.itcast.hibernate;

import java.util.Date;

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

import cn.itcast.hibernate.domain.User;

public class Base {
	public static void main(String[] args) {
		Configuration cfg = new Configuration(); //生成一个Configuration对象
		cfg.configure(); //调用configure()方法加载映射文件
		SessionFactory sf = cfg.buildSessionFactory(); //产生一个SessionFactory
	
		Session s = sf.openSession(); //开启session
		Transaction tx = s.beginTransaction(); //开启事务
		
		User user = new User();
		user.setBirthday(new Date());
		user.setName("name");
		
		s.save(user); //把user对象保存在session中
		tx.commit(); //提交事务
		s.close(); //关闭session
		System.out.println("end");
	}

}
