【基于Maven的Hibernate增删改查】-优快云博客

本文通过一个简单的例子展示了如何使用 Hibernate 框架实现基本的增删改查操作，并附带了完整的源代码及 SQL 输出。

1、Hibernate增删改查源码如下:

package cn.com.test.hibernatedemo;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;

import cn.com.vo.hibernatedemo.UserVO;

/**
 * Hello world!
 * 
 */
public class App {
	public static void main(String[] args) {
		System.out.println("Hello World!");
		UserVO vo = new UserVO(1, "gaojignosng", "11", 30);
		
		 saveUser(vo);
		
		 getUser(1);
		 
		 loadUser(1);
		
		 vo.setName("xxxxxxxxx");
		 updateUser(vo);
			
		 deleteUser(vo);
	}
	
	public static void saveUser(UserVO vo ){
		Session session = HibernateUtil.getSessionFactory().openSession();
		Transaction beginTransaction = session.beginTransaction();
		try {
			session.save(vo);
			beginTransaction.commit();
			System.out.println("------saveUser------"+vo);
		} catch (HibernateException e) {
			beginTransaction.rollback();
			e.printStackTrace();
		}
		session.close();
	}
	
	public static void getUser(int id){
		Session session = HibernateUtil.getSessionFactory().openSession();
		try {
			UserVO vo = (UserVO) session.get(UserVO.class, id);
			System.out.println("------getUser------"+vo);
		} catch (HibernateException e) {
			 
			e.printStackTrace();
		}
		session.close();
	}
	
	
	public static void loadUser(int id){
		Session session = HibernateUtil.getSessionFactory().openSession();
		try {
			UserVO vo = (UserVO) session.load(UserVO.class, id);
			System.out.println("------loadUser------"+vo);
		} catch (HibernateException e) {
			e.printStackTrace();
		}
		session.close();
	}
	
	public static void updateUser(UserVO vo){
		Session session = HibernateUtil.getSessionFactory().openSession();
		Transaction transaction = session.beginTransaction();
		try {
		  session.update(vo);
		  transaction.commit();
		  System.out.println("------updateUser------"+vo);
		} catch (HibernateException e) {
			transaction.rollback();
			e.printStackTrace();
		}
		session.close();
	}
	
	public static void deleteUser(UserVO vo){
		Session session = HibernateUtil.getSessionFactory().openSession();
		Transaction transaction = session.beginTransaction();
		try {
		  session.delete(vo);
		  transaction.commit();
		  System.out.println("------deleteUser------"+vo);
		} catch (HibernateException e) {
			transaction.rollback();
			e.printStackTrace();
		}
		session.close();
	}
}

2、SQL语句输出如下：
