1、新建Web Project工程

2、导入所需jar包

3、Student.java

package com.itmyhome;

import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="T_STUDENT")
public class Student extends BizEntity{
	private String name;
	private String score;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getScore() {
		return score;
	}
	public void setScore(String score) {
		this.score = score;
	}
	
}

Teacher.java

package com.itmyhome;

import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="T_TEACHER")
public class Teacher extends BizEntity{
	private String name;
	private String title;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	
}

BizEntity.java

package com.itmyhome;

import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import org.hibernate.annotations.GenericGenerator;

public class BizEntity {
	private String id;

	@Id @GeneratedValue(strategy=GenerationType.AUTO,generator="bizGenerator")
	@GenericGenerator(strategy = "uuid", name = "bizGenerator")
	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	

	
}

BizEntity.java是所有实体类的父类，id自动生成策略为uuid

4、hibernate.hbm.xml

<?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>
		<property name="dialect">org.hibernate.dialect.OracleDialect</property>
		<property name="connection.url">jdbc:oracle:thin:@172.16.1.4:1521:orcl</property>
		<property name="connection.username">username</property>
		<property name="connection.password">123</property>
		<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
		<property name="current_session_context_class">thred</property>
		
		<property name="show_sql">true</property>
		<property name="format_sql">true</property>
		<property name="hbm2ddl.auto">true</property>

</hibernate-mapping>

5、Test.java测试

package com.itmyhome;

import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;

public class Test {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		//new SchemaExport(new AnnotationConfiguration().configure()).create(true, true);

                  Teacher t = new Teacher();
                  t.setName("张三");
  
                  Configuration cfg = new AnnotationConfiguration();
                  SessionFactory factory =cfg.configure().buildSessionFactory();
                  Session session = factory.openSession();
                  session.beginTransaction();
                  session.save(t);
                  session.getTransaction().commit();
	}
}

SchemaExport自动生成数据表

运行程序：
