hibernate helloworld(xml)

首先导入相关的hibernate 包和 mysql的包
 
接着设置映射类
public class Student { private int id; private String name;
 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 Student() {  super();  // TODO Auto-generated constructor stub }
 public Student(int id, String name) {  super();  this.id = id;  this.name = name; }
}
接着是映射文件hibernate.hbm.xml:

 <?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.qi.pojo">    <class name="Student">     <id name="id"></id>     <property name="name"></property>    </class></hibernate-mapping>

接着是配置文件hibernate.cfg.xml:

 <?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">
<!-- Generated by MyEclipse Hibernate Tools.                   --><hibernate-configuration>
    <session-factory>        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>        <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>        <property name="connection.username">root</property>        <property name="connection.password">root</property>        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>        <mapping resource="com/qi/pojo/hibernate.hbm.xml"/>    </session-factory>
</hibernate-configuration>

接着是text:

import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;
import com.qi.pojo.Student;
public class test1 {public static void main(String[] args) { System.out.println("begin"); Student student=new Student(1,"qi"); Configuration config=new Configuration(); config.configure(); SessionFactory factory=config.buildSessionFactory(); Session session=factory.openSession(); session.beginTransaction(); session.save(student); session.getTransaction().commit(); session.close();}}
