myeclipse下hibernate入门实例介绍

myeclipse下hibernate初步实例

说明:本例采用myeclipse+sqlserver2000

hibernate版本为3.0.

数据库驱动为:jtds-1.0.2。

1。配置myeclipse环境(eclipse-SDK- 3.1.1+myeclipse4.1.1GA_E3.1)。

2.配置好sqlserver2000数据库:建立数据库:goto . 表 test_products

CREATE TABLE [dbo].[test_products] ([id] [int] IDENTITY (1, 1) NOT NULL ,[aotoid] [char] (50) COLLATE Chinese_PRC_CI_AS NULL ,[username] [char] (50) COLLATE Chinese_PRC_CI_AS NULL ,[price] [int] NULL ,[amount] [int] NULL)id为自动编号。

3。新建项目–myeclipse–Web Project 。本例为: prodcast

4. 右单击prodcast,加入myeclipse的hibernate.并在此工程 中建立数据连结。

建立完成后,在src下自动生成hibernate.cfg.xml,内容为:

sajdbc:jtds:sqlserver://192.168.1.8 8:1433;DatabaseName=goto  org.hibernate.dialect.SQLServerDialect&l t;/property>hcsysnet.sourceforge.jtds.jdb c.Driver

5。建立:Product.java:

package test.hibernate;import java.io.Serializable;public class Product implements Serializable {private static final long serialVersionUID = 3858043967100350732L;private Integer id;private String aotoid;private String username;private Integer price;private Integer amount;public Integer getAmount() {return amount;}public void setAmount(Integer amount) {this.amount = amount;}public String getAotoid() {return aotoid;}public void setAotoid(String aotoid) {this.aotoid = aotoid;}public Integer getPrice() {return price;}public void setPrice(Integer price) {this.price = price;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}}

6.建立InsertProduct.java

package test.hibernate;import org.hibernate.SessionFacTory;import org.hibernate.Transaction;import org.hibernate.cfg.*;import org.hibernate.classic.Session;public class InsertProduct {public static void main(String[] args) {SessionFacTory sf = new Configuration().configure().buildSessionFacTory();Session session = sf.openSession();Transaction tx = session.beginTransaction();Product p = new Product();p.setAotoid("1");p.setUsername("zhang");p.setAmount(new Integer(10));p.setPrice(new Integer(10));System.out.println(p+"_______________1");try{session.save(p);tx.commit();session.close();System.out.println(p+"_______________2");}catch(Exception ex){ex.printStackTrace();}}}

7.在test.hibernate包下建立:Product.hbm.xml.

8.打开hibernate.cfg.xml. 加入:

形成完整的config:

sajdbc:jtds:sqlserver://192.168.1.8 8:1433;DatabaseName=gotoorg.hibernate.dialect.SQLServerDialect&l t;/property>hcsysnet.sourceforge.jtds.jdb c.Driver

9.运行InsertProduct.java就可以看到数据库goto表 test_products中增加了一条记录。
