hibernate中报SessionFactory为空

这是我的hibernate.cfg.xml文件的内容
<?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">

    <!-- 数据表的方言 -->

    <mapping resource="com/test/hibernate/Student.hbm.xml"/>

这是我映射的Student.hbm.xml文件的内容
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">


















这是我测试类的内容
package com.test.Junit;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import com.test.hibernate.Student;

public class TestHiber {
/**
* 获得关系映射对象文件
/
private SessionFactory sessionFactory=null;
/
*
类似于JDBC中的Connection
*/
private Session session;
/
*
* 获得事物对象
*/
private Transaction transaction;
private Configuration config;
@Before
public void init(){
//读取配置文档hibernate.cfg.xml文件
config = new Configuration().configure("hibernate.cfg.xml");
//创建服务注册对象
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().
applySettings(config.getProperties()).buildServiceRegistry();
//创建会话工厂对象
sessionFactory = config.buildSessionFactory(serviceRegistry);
//会话对象
session = sessionFactory.getCurrentSession();
//打开事物
transaction = session.beginTransaction();
}

@After
public void destory(){
    transaction.commit();//提交事务
    session.close();//关闭会话
    sessionFactory.close();//关闭会话工厂对象
}
@Test
public void test() {
    Student student = new Student(1, "Minions", "sex", 10);
    session.save(student);
}

}

看看你是不是jar冲突,导致的ClassNotFoundException 所以获取为空
