環境準備：jdk  eclipse   hibernate、mysql jar包

專案截圖：

Student是根據配置檔案建立表，Teacher是根據註解建立表

Student.java

package com.java1234.model;

public class Student {
	private long id;
	private String name;
	public long getId() {
		return id;
	}
	public void setId(long id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
}
 

Student.hbm.xml

<?xml version="1.0"?>

Teacher.java

package com.java1234.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

import org.hibernate.annotations.GenericGenerator;

@Entity
@Table(name="t_teacher")//對映表名

	private String name;
	
        //主鍵

	}
	@Override
	public String toString() {
		return "Teacher [id=" + id + ", name=" + name + "]";
	}
	
}
 

hibernate.cfg.xml      配置檔名稱寫死

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

</hibernate-configuration>

HibernateUtil.java

package com.java1234.util;

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

public class HibernateUtil {
	private static final SessionFactory sessionFactory = buildSessionFactory();
	
	private static SessionFactory buildSessionFactory() {
		Configuration configuration = new Configuration().configure();//底層預設載入配置src目錄下的hibernate.cfg.xml配置檔案，所以配置檔名稱寫死
		ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();//例項化服務登記
		SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);//獲取Session工廠
		return sessionFactory;
	}
	
	public static SessionFactory getSessionFactory() {
		return sessionFactory;
	}
}

測試類：執行測試類就自動建立了

package com.java1234.service;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

import com.java1234.model.Student;

public class StudentTest {
	private SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
	public static void main(String[] args) {
		Session session = sessionFactory.openSession();
		session.beginTransaction();//開啟事務
		
		/*Student s = new Student();
		s.setName("張三");*/
		
		
		session.getTransaction().commit();//提交事務
		session.close();//關閉session
		sessionFactory.close();
	}
	
}
