本文展示了Hibernate配置文件(hibernate.cfg.xml)及实体映射文件(Users.hbm.xml)的具体内容，并通过一个简单的Java测试类演示了如何使用这些配置。然而，在运行过程中遇到了XML读取错误，异常信息显示系统标识符缺少正确的引号。

hibernate.cfg.xml里面的代码
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

</hibernate-configuration>
Users.hbm.xml里面的代码
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

Tes.t.java里面的代码
package cn.jbit.test;

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

import cn.jbit.bean.Users;

public class Test {

/**
* @param args
*/
public static void main(String[] args)
{

/**
* @param args
*/

Configuration conf = new Configuration().configure();
SessionFactory sf =conf.buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();
Users users= new Users();

users.setName("zhangsan");
users.setPassword("12345");
users.setTelephone("123213");
users.setIsadmin("是");
users.setUsername("dfjdsj");
session.save(users);
tx.commit();
session.close();

}

}
