急！初学Hibernate，弄了2天，找不到错误...

package cn.itcast.helloWorld;

public class User {
	private int id;
	private String name;
	
	public User(){}
	
	public User(int id,String name){
		this.id=id;
		this.name=name;
	}
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}

}

测试类：

package cn.itcast.helloWorld;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class App {
	public static void main(String args[]) {
		User user=new User(1,"张三");
		Configuration cfg=new Configuration();
		cfg.configure("hibernate.cfg.xml");
		SessionFactory sessionFactory=cfg.buildSessionFactory();
		Session session=sessionFactory.openSession();
		Transaction ts=session.beginTransaction();
		session.save(user);
		ts.commit();
		session.close();
	}
	

}
