Unable to perform unmarshalling at line number 0 and column 0 in RESOURCE hibernate.cfg.xml. Message: null

java 代码：
package org.ljh.apps;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.ljh.entity.User;

public class AppTest {
public static void main(String[] args) {
AppTest app = new AppTest();
app.testAdd();
}
public void testAdd() {
//加载配置文件
//创建SessionFactory对象
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
//使用SessionFactory创建Session对象
Session session =sessionFactory.getCurrentSession();
//开启事务
Transaction tx =session.beginTransaction();
//CRUD
User user = new User();
user.setUsername("胡汉三");
user.setPassword("123456");
user.setAddress("回来了");
//调用Session的方法实现CRUD
session.save(user);
//提交事务
tx.commit();
//关闭资源
session.close();
}
}
