loadtest.java

实现一些hibernate底层的东西

package com.bjsxt.hibernate;

import junit.framework.TestCase;

import org.hibernate.LockMode;
import org.hibernate.Session;

public class LoadTest extends TestCase {
	
	public void testLoad1(){
		Session session = null;
		try{
			session = HibernateUtils.getSession();
			session.beginTransaction();
			Inventor inv = ( Inventor )session.load( Inventor.class, 1 , LockMode.UPGRADE );
			System.out.println( inv.getItemName() );
			System.out.println( inv.getQuantity() );
			System.out.println( inv.getQuantity() - 200 );
			session.update( inv );
			
			session.getTransaction().commit();
		}catch( Exception e ){
			e.printStackTrace();
			session.getTransaction().rollback();
		}finally{
			HibernateUtils.closeSession(session);
		}
	}
	
	public void testLoad2(){
		Session session = null;
		try{
			session = HibernateUtils.getSession();
			session.beginTransaction();
			Inventor inv = ( Inventor )session.load( Inventor.class, 1 , LockMode.UPGRADE );
			System.out.println( inv.getItemName() );
			System.out.println( inv.getQuantity() );
			System.out.println( inv.getQuantity() - 200 );
			session.update( inv );
			
			session.getTransaction().commit();
		}catch( Exception e ){
			e.printStackTrace();
			session.getTransaction().rollback();
		}finally{
			HibernateUtils.closeSession(session);
		}
	}
}
