test_h.java

用struts+hibernate实现案例

package hibernate;

import org.hibernate.*;
import org.hibernate.cfg.*;
import java.util.*;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.BasicConfigurator;
import org.apache.log4j.xml.*;


public class test_h {
	public List getData(String name){
		List list;

		Logger logger=Logger.getRootLogger();
		logger.error("config");
		//Configuration cfg=new Configuration();
		//logger.error("config1");
		//cfg.configure();
		//SessionFactory sf=cfg.buildSessionFactory();
		//Session session=sf.openSession();
		HibernateUtil.setSession();
		Session session=HibernateUtil.currentSession();
		
		logger.error("session");
		Query query=session.createQuery("from User u where u.name like :name");
		query.setString("name", "%"+name+"%");
		list=query.list();
		logger.error("list");
		return list;	
	}
	
	public void add(){
		Logger logger=Logger.getRootLogger();
		Configuration cfg=new Configuration();
		cfg.configure();
		SessionFactory sf=cfg.buildSessionFactory();
		Session se=sf.openSession();
		
		logger.error("se");
		
		Transaction tx=se.beginTransaction();
		
		User user=new User();
		user.setNo(10);
		user.setName("din");
		
		se.save(user);
		
		tx.commit();
		
		se.close();
		
		
	}
