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();

}

}
