利用Netbeans5.5生成功能来开发Hibernate3

步骤如下。

需要安装Netbeans5.5或以上版本。

1.使用Netbeans5.5生成EntityClass

2.给EntityClass的id字段注明生成方式，如：@GeneratedValue

3.使用AnnotationConfiguration

注）推荐proxool-0.9.0RC3 

import org.hibernate.Session;  
import org.hibernate.SessionFactory;  
import org.hibernate.Transaction;  
import org.hibernate.cfg.AnnotationConfiguration;  
import org.hibernate.cfg.Environment;  
 
import com.hb.pack_01.model.P01_Customer;  
 
 
public class BusinessService ...{  
 
    public static SessionFactory sessionFactory;  
 
    static ...{  
        try ...{  
            AnnotationConfiguration cfg = new AnnotationConfiguration();  
            cfg.configure("hibernate.cfg.xml");  
            cfg.setProperty(Environment.HBM2DDL_AUTO, "create-drop");  
            cfg.addPackage("com.hb.pack_01.model");  
            cfg.addAnnotatedClass(P01_Customer.class );  
            sessionFactory = cfg.buildSessionFactory();  
        } catch (Exception e) ...{  
            e.printStackTrace();  
        }  
    }  
      
    public void saveCustomer(P01_Customer customer) throws Exception ...{  
        Session session = sessionFactory.openSession();  
        Transaction tx = null;  
        try ...{  
            tx = session.beginTransaction();  
            session.save(customer);  
            tx.commit();  
        } catch (Exception e) ...{  
            if (tx != null) ...{  
                tx.rollback();  
            }  
            throw e;  
        } finally ...{  
            session.close();  
        }  
    }  
      
    public void test() throws Exception ...{  
 
        P01_Customer customer = new P01_Customer();  
        customer.setName("Laosan Zhang");  
        customer.setSex(''M'');  
        customer.setCustomerDescription("A good citizen!");  
        saveCustomer(customer);  
    }  
      
    public static void main(String[] args) throws Exception ...{  
          
        new BusinessService().test();  
        sessionFactory.close();  
    }  
}  

 Hibernate配置文件：

1. xml version=''1.0'' encoding=''utf-8''?> 
3.         "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  
4.         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> 
5.  
6. <hibernate-configuration> 
7.     <session-factory> 
8.          
9.         <property name="hibernate.connection.provider_class"> 
10.             org.hibernate.connection.ProxoolConnectionProvider  
11.         property> 
12.         <property name="hibernate.proxool.pool_alias">MSSQL2000POOLproperty> 
13.         <property name="hibernate.proxool.xml">Proxool.xmlproperty> 
14.          
15.         <property name="dialect">

26.  连接池配置文件：
