myeclipse创建hibernate工程

1.创建数据库：
from blog http://www.cnblogs.com/zhaocundang/p/9061959.html
使用navicat mysql IDE：
创建数据库 bookshop
创建表
CREATE TABLE books(id INT PRIMARY KEY auto_increment,Bookname VARCHAR(50),Bookprice VARCHAR(40));
ok 数据库部分整完。

打开myeclipse创建web工程：

finish

创建数据库连接db browser

如果没有的话，在other查找db browser

右键new

填信息

测试连接

finish

展开数据库，右键数据库表book,反向工程

finish

右键工程导入hibernate库

取消勾

整个工程：

创建个测试类：
插入数据

package test;

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

import pojo.Book;


public class mytest {

     static Configuration cfg = null;
     static SessionFactory sessionFactory = null;
     
    
    public static void insert(){
        
        cfg = new Configuration();
        cfg.configure();
        sessionFactory = cfg.buildSessionFactory();
        
        Configuration cfg = new Configuration();
        cfg.configure();
 
        SessionFactory sessionFactory = cfg.buildSessionFactory();
     
     
        Session session = sessionFactory.openSession();
 
        Transaction tx = session.beginTransaction();
 
         Book book = new Book();
          
         book.setBookname("语文");
         book.setBookprice("18元");
          
        //调用session的方法实现添加
        session.save(book);
        
//      第六步 提交事务
        tx.commit();

//      第七步 关闭资源
        session.close();
        sessionFactory.close();
        
    }
    
    public static void main(String[] args){
 
        insert();
    
    }

 
}

更新数据

package test;

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

import pojo.Book;


public class update {

     static Configuration cfg = null;
     static SessionFactory sessionFactory = null;
     
    
    public static void update(){
        
        cfg = new Configuration();
        cfg.configure();
        sessionFactory = cfg.buildSessionFactory();
        
        Configuration cfg = new Configuration();
        cfg.configure();
 
        SessionFactory sessionFactory = cfg.buildSessionFactory();
     
     
        Session session = sessionFactory.openSession();
        Transaction tx= session.beginTransaction();
        
        //修改第一条数据
         Book book =(Book)session.get(Book.class, new Integer(1));
          
         book.setBookname("语文");
         book.setBookprice("20元");
          
        //保存一下
        session.save(book);
        
//      第六步 提交事务
        tx.commit();

//      第七步 关闭资源
        session.close();
        sessionFactory.close();
        
    }
    
    public static void main(String[] args){
 
        update();
    
    }

 
}

删除数据

package test;

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

import pojo.Book;


public class delete {

     static Configuration cfg = null;
     static SessionFactory sessionFactory = null;
     
    
    public static void delete(){
        
        cfg = new Configuration();
        cfg.configure();
        sessionFactory = cfg.buildSessionFactory();
        
        Configuration cfg = new Configuration();
        cfg.configure();
 
        SessionFactory sessionFactory = cfg.buildSessionFactory();
     
     
        Session session = sessionFactory.openSession();
 
        Transaction tx = session.beginTransaction();
 
        //删除第三条数据
         Book book =(Book)session.get(Book.class, new Integer(3));
          
         session.delete(book);
          
        
//      第六步 提交事务
        tx.commit();

//      第七步 关闭资源
        session.close();
        sessionFactory.close();
        
    }
    
    public static void main(String[] args){
 
        delete();
    
    }

 
}

查询数据

package test;

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

import pojo.Book;


public class select {

     static Configuration cfg = null;
     static SessionFactory sessionFactory = null;
     
    
    public static void select(){
        
        cfg = new Configuration();
        cfg.configure();
        sessionFactory = cfg.buildSessionFactory();
        
        Configuration cfg = new Configuration();
        cfg.configure();
 
        SessionFactory sessionFactory = cfg.buildSessionFactory();
     
     
        Session session = sessionFactory.openSession();
 
        Transaction tx = session.beginTransaction();
 
         Book book =(Book)session.get(Book.class, new Integer(1));
        System.out.println("书的ID是:"+book.getId()+"\n"+"书名是:"+book.getBookname()+"\n"+"价格是:"+book.getBookprice());
         
//      第六步 提交事务
        tx.commit();

//      第七步 关闭资源
        session.close();
        sessionFactory.close();
        
    }
    
    public static void main(String[] args){
 
        select();
    
    }

 
}
